The beneficial effects of the utility model: the utility model is by providing a kind of box-type substation with the transformer room door interlocked control, at transformer room door travel switch is set, trip(ping) circuit at high-voltage switch gear is interlocked, forbid the charged danger that enters the transformer room, guaranteed operating personnel's personal safety.
Description of drawings
Fig. 1 is the structural representation of existing box-type substation.
Fig. 2 is the circuit diagram of transformer room door interlocked control in the utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously the utility model is further described.
As depicted in figs. 1 and 2, this box-type substation with the transformer room door interlocked control comprises transformer room 100, transformer room 100 comprises transformer 130, the first transformer room door 110, the second transformer room door 120 and interlock, is provided with isolating and protecting grid 111 between transformer 130 and the first transformer room door 110; Transformer 130 is connected with high-voltage switch gear.
Described interlock comprises the first travel switch 1XL, the second travel switch 2XL and circuit breaker Q F: described the first travel switch 1XL is arranged on the isolating and protecting grid 111, and the second travel switch 2XL is arranged on the second transformer room door 120; The end of described the first travel switch 1XL connects power supply, and the other end connects high-voltage switch gear; The end of described the second travel switch 2XL connects power supply, and the other end connects high-voltage switch gear; The end of described circuit breaker Q F connects power supply, and the other end connects high-voltage switch gear.
In order better to warn prompting for operating personnel, between described the first travel switch 1XL and power supply, the second travel switch 2XL and power supply, be connected respectively a ruddiness warning lamp and buzzer warning device; Between circuit breaker Q F and power supply, be connected the green glow warning lamp.
Operation of the present utility model is as follows: when the first transformer room door 110 and the second transformer room door 120 were closed fully, the first travel switch 1XL and the second travel switch 2XL disconnected, and high-voltage switch gear just can close a floodgate, and the green glow warning lamp is connected; Any one is not closed fully in the isolating and protecting grid 111 of the first transformer room door 110 and the second transformer room door 120, then corresponding the first travel switch 1XL or the second travel switch 2XL are closed, the ruddiness warning lamp is connected, the buzzer warning device is connected, high-voltage switch gear has been connected circuit breaker QF once closing a floodgate, circuit breaker Q F automatic trip then can not be finished and send electricity, only have when the first travel switch 1XL and the second travel switch 2XL all disconnect, high-voltage switch gear could close a floodgate and send electricity.
When high-voltage switch gear closed a floodgate, transformer was to be in charged work, did not just allow to enter the transformer room; If when transformer is worked, need to enter the transformer room, open isolating and protecting grid 111, the first travel switch 1XL action closure, connected the circuit breaker Q F of high-voltage switch gear, the high-voltage switch gear tripping operation has disconnected the high voltage side of transformer power supply, so just can the charged danger that enters the transformer room of total ban.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection range of the utility model claims.
