Abstract
The present invention relates to a kind of isolation switch device, include crust of the device, feature is: be provided with base in crust of the device, base is provided with stationary contact bridge, and stationary contact bridge is arranged with case.Meanwhile, casing base is provided with socket, and case top is provided with cover plate.Further, the side of cover plate is provided with contact supporting assembly, and the opposite side of cover plate is provided with locking part.Like this, case and contact supporting assembly form isolation module, allow the major loop of isolation module first connect, then auxiliary connection, and body power supply is connected, and electromagnet coil power, body major loop closes, and switch normally works.Thus, employing is auxiliary first to be disconnected, and guarantees that body power supply disconnects and electromagnet does not have electricity, so after guaranteeing that main body major loop disconnects, then disconnect the major loop of isolation module, to reach fail safe, and operation is quite convenient.
Description
Technical field
The present invention relates to a kind of switching device, particularly relate to a kind of isolation switch device.
Background technology
The function of circuit breaker, contactor, thermal relay well combines together by control and protective switching device (CPS); the work that each apportion appliance component protective feature of reasonable coordination, control characteristic coordinate; conventional motors can be replaced and control application, also can be widely used in the occasion such as automatic centralized control system and Fieldbus Based dcs.
Isolating switch is a kind of switchgear not having arc-control device, is mainly used to the circuit disconnecting zero load electric current, insulating power supply, has obvious cut-off point when gate-dividing state, to ensure the safety inspection of other electric equipments.Reliably normal duty electric current and short-circuit current can be passed through when "on" position.Because it does not have special arc-control device, load current and short circuit current can not be cut off.Therefore, isolating switch can only operate when circuit is disconnected by circuit breaker, forbids on-load operation, in order to avoid cause serious equipment and personal injury.
There is the risk of fail safe and the inconvenience of operability in traditional isolation module.Must first disconnecting body major loop, if do not disconnected, directly unpluging isolation module, can electric arc burn be caused.Very strict to operational norm and sequence requirement, careless slightly meeting leads to serious consequence.
Summary of the invention
Object of the present invention is exactly to solve the above-mentioned problems in the prior art, provides a kind of isolation switch device.
Object of the present invention is achieved through the following technical solutions:
A kind of isolation switch device, include crust of the device, wherein: in described crust of the device, be provided with base, described base is provided with stationary contact bridge, described stationary contact bridge is arranged with case, and described casing base is provided with socket, and described case top is provided with cover plate, the side of described cover plate is provided with contact supporting assembly, and the opposite side of described cover plate is provided with locking part.
Further, above-mentioned a kind of isolation switch device, wherein: described contact supporting assembly includes receiver, is provided with elastic parts in described receiver, described elastic parts top is provided with contact.
Further, above-mentioned a kind of isolation switch device, wherein: described elastic parts is spring.
Again further, above-mentioned a kind of isolation switch device, wherein: described housing sidewall is provided with slotted eye.
The advantage of technical solution of the present invention is mainly reflected in: case and contact supporting assembly form isolation module, allows the major loop of isolation module first connect, then auxiliary connection, and body power supply is connected, and electromagnet coil power, body major loop closes, and switch normally works.Thus, employing is auxiliary first to be disconnected, and guarantees that body power supply disconnects and electromagnet does not have electricity, so after guaranteeing that main body major loop disconnects, then disconnect the major loop of isolation module, to reach fail safe, and operation is quite convenient.
Accompanying drawing explanation
Object of the present invention, advantage and disadvantage, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below.These embodiments are only the prominent examples of application technical solution of the present invention, allly take equivalent replacement or equivalent transformation and the technical scheme that formed, all drop within the scope of protection of present invention.In the middle of these accompanying drawings,
Fig. 1 is the unitary construction schematic diagram of isolation switch device;
Fig. 2 is the operating diagram that contact flicks rear auxiliary disconnection;
Fig. 3 is the operating diagram that case mentions the disconnection of rear major loop;
Fig. 4 is the operating diagram that isolation switch device disconnects completely.
Embodiment
A kind of isolation switch device as shown in figures 1-4, includes crust of the device 1, and its unusual part is: be provided with base 2 in the crust of the device 1 that the present invention adopts.Specifically, base 2 is provided with stationary contact bridge 3.Further, stationary contact bridge 3 is arranged with case 4.Meanwhile, be provided with socket 5 bottom case 4, case 4 top is provided with cover plate 6.As shown in Figure 1, the side of cover plate 6 is provided with contact 9 supporting assembly, and the opposite side of cover plate 6 is provided with locking part 7.
With regard to the present invention one preferably execution mode, consider the effect that can realize postponing interlock, contact 9 supporting assembly that the present invention adopts includes receiver 8.Specifically, be provided with elastic parts in this receiver 8, and elastic parts top is provided with contact 9.Moreover consider upspringing smoothly of contact 9, elastic parts is spring 10.
In conjunction with actual service condition of the present invention: include disconnection process and process of closing.
Disconnection process: as shown in Figure 2, slips off locking part 7 to the right, mentions when cover plate 6(just pulls up and has slight feel), the contact 9 of first auxiliary contact 9 supporting assembly is first upspring, and realizes auxiliary disconnection.Meanwhile, along with auxiliary disconnection, now body power supply also disconnects thereupon, and electromagnet coil will not have electricity yet, and then guarantees body power-off.
Then, as shown in Figure 3, continue to mention cover plate 6, when the stroke of cover plate 6 and case 4 reaches terminal, socket 5 is upwards raised together along with case 4, and the major loop of isolation module disconnects then.Further, the cover plate 6 of mentioning can be inserted into case 4, case 4 sidewall grooved hole, and specialize in the position that locking part 7 inserts, so far whole disconnection process completes, and the position relationship of all parts as shown in Figure 4.
To close process: the open union that moves right latch fitting 7, by lower cover 6, socket 5 first contacts with stationary contact bridge 3 in the process.Afterwards, continue to press lower cover 6, with auxiliary contact 9 supporting assembly by earth.Then, be moved to the left locking part 7, block case 4, it can not be mentioned.
Now realize auxiliary function of closing, body power supply is energized, and electromagnet coil power then, body major loop closes, and switch normally works.
Can be found out by above-mentioned character express, after adopting the present invention, case and contact supporting assembly form isolation module, allow the major loop of isolation module first connect, then auxiliary connection, body power supply is connected, electromagnet coil power, body major loop closes, and switch normally works.Thus, employing is auxiliary first to be disconnected, and guarantees that body power supply disconnects and electromagnet does not have electricity, so after guaranteeing that main body major loop disconnects, then disconnect the major loop of isolation module, to reach fail safe, and operation is quite convenient.
