Abstract
The utility model relates to a tripping protection device of a transformer room net door, which comprises a transformer room, a net door and an outer door, wherein the net door and the outer door are used for opening the transformer room. A travel switch is arranged on the net door. One end of the travel switch is connected with a power supply, and the other end thereof is electrically connected with a shunt coil of a breaker arranged in a high-voltage chamber. Compared with the prior art, as the travel switch protection is added on the net door, the protection on human bodies is added, and the safety is enhanced; the structure is simple, and the cost is low.
Description
Technical field
The utility model relates to a kind of transformer room net door trip protection device.
Background technology
Present box-type transformation station one has three chambers: low-pressure chamber, transformer room, hyperbaric chamber.But protective device is not set in the transformer room, all can personnel's personal safety be worked the mischief when the misoperation when the maintainer overhauls or others open the transformer room.
The utility model content
The utility model technical issues that need to address are, provide a kind of transformer room net door trip protection device to reach the purpose of tripping transformer station high-pressure section when opening the net door when the misoperation.
In order to solve the problems of the technologies described above the technical solution of the utility model be; a kind of transformer room net door trip protection device; comprise the transformer room; open the net door and the external door of transformer room; on the described net door travel switch is installed; one end of described travel switch is connected with power supply, and the other end is electrically connected with the circuit breaker shunt opening coil that is arranged on the hyperbaric chamber.
On the described external door key switch is installed, travel switch is electrically connected with circuit breaker shunt opening coil by key switch.
The utility model has compared with prior art increased the travel switch protection on the net door, increased the protection to human body, has improved fail safe, and simple in structure, and cost is lower.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details;
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model schematic diagram;
In Fig. 1,1, the transformer room, 2, the net door, 3, external door, 4, travel switch, 5, key switch, 6, circuit breaker shunt opening coil.
Embodiment
Shown in Fig. 1-2; a kind of transformer room net door trip protection device; comprise transformer room 1; open the net door 2 and the external door 3 of transformer room 1; on the described net door 2 travel switch 4 is installed; one end of described travel switch 4 is connected with power supply, and the other end is electrically connected with the circuit breaker shunt opening coil 6 that is arranged on the hyperbaric chamber.On the described external door 3 key switch 5 is installed, travel switch 4 is electrically connected with circuit breaker shunt opening coil 6 by key switch 5.Often open net door 2 shutoff stroke switches 4 contacts, and net door 2 opening travel switches 4 contacts are normally closed.
When not using key to open external door 3, key switch 5 is in on-state all the time, and when key switch 5 was connected, when net door 2 was closed, travel switch 4 disconnected, and circuit breaker shunt opening coil 6 must not be electric, and high-voltage switch gear normally moves.Connect when key switch, net door 2 and open, travel switch 4 closures, circuit breaker shunt opening coil 6 gets electric, high-voltage switch gear dropout tripping operation.
When the staff overhauls, use key that key switch 5 is disconnected, no matter stroke quick closing valve 4 disconnects or connects, and circuit breaker separate winding 6 is invocation point not, and the high-voltage switch gear operate as normal makes things convenient for the maintainer to overhaul.
