Reference numeral:
The VC-power supply; The DL-circuit breaker; The K-air switch;
The S-voice guard; The G-flash alarm.
Embodiment
With reference to figure 1, the schematic diagram of the high-tension switch cabinet tripping alarm system that Fig. 1 provides for the utility model embodiment.
High-tension switch cabinet tripping alarm system as shown in Figure 1, that present embodiment provides comprises power supply VC, circuit breaker DL and alarm.The main contacts that circuit breaker DL comprises auxiliary contact and is used for being connected with high-tension line; Main contacts can link with auxiliary contact switch, and main contacts and the auxiliary contact switch of circuit breaker DL oppositely link, and that is to say; If the main contacts of circuit breaker DL is a normally closed interlock; Then auxiliary contact are normally open contact, and when main contacts transferred off-state to by closure state, auxiliary contact then transferred closure state to by off-state.
Power supply VC is connected with auxiliary contact one end of circuit breaker DL, and alarm is connected with the other end of the auxiliary contact of circuit breaker DL, and auxiliary contact and the circuit between the alarm of circuit breaker DL are in series with air switch K.This air switch K is a normally closed switch; When the alarm circuit operate as normal, be in closure state; When the maintenance circuit, air switch K is broken off to break off alarm circuit, prevent that misoperation from producing false alarm, makes the convenient and swift of high-tension switch cabinet tripping alarm system maintenance.
This high-tension switch cabinet tripping alarm system can be provided with a circuit breaker DL, and the main contacts of circuit breaker DL can be connected with a high-tension line; Certainly, a plurality of circuit breaker DL can be set also, the main contacts of each circuit breaker DL is connected with a high-tension line.
In practical application, the high-tension switch cabinet tripping alarm system that present embodiment provides can be applied to the electric substation of coal mining enterprise particularly, such as 110KV electric substation, also can be applied to the electric substation of other types.Circuit breaker DL can be the circuit breaker DL of a plurality of parallel connections, and auxiliary contact one end of each circuit breaker DL is connected with the input of alarm, and the other end of the auxiliary contact of each circuit breaker DL is connected with power supply 1.
Circuit breaker DL can be one or more circuit breakers.Power supply VC is DC power supply or AC power, can confirm the type of power supply VC according to the operating voltage of alarm.
Alarm can be voice guard S and/or flash alarm G, and particularly, alarm can be voice guard S, also can be flash alarm G, can certainly use voice guard S and flash alarm G simultaneously.In addition, alarm can have display screen, and display screen can show the numbering of dead electricity circuit, makes that the monitor staff is faster, confirm high pressure dead electricity circuit easily.
In practical application, the main contacts of circuit breaker DL is connected with the high-tension line of 110KV electric substation, an end of the auxiliary contact of circuit breaker DL is connected with power supply VC, and the other end of the auxiliary contact of circuit breaker DL is connected with alarm.When the high-tension line normal power supply, the main contacts of circuit breaker DL is closed, and high-tension line is a path, is coal mining enterprise's power supply.
When one or more high-tension lines broke down, the main contacts of the circuit breaker DL on each high-tension line was opened automatically, the high-tension line dead electricity; This moment, auxiliary contact and the main contacts of circuit breaker DL linked, and auxiliary contact are closed, the circuit of energized VC and alarm; Alarm gets the electrician and does, sound alarm or warning blinker, perhaps sound simultaneously alarm and warning blinker; And according to the monitor signal of each circuit breaker monitoring circuit; Judge and show the high-tension switch cabinet numbering of trip breaker,, in time repair high-tension line to warn monitor staff's high-tension line generation dead electricity fault immediately.
The high-tension switch cabinet tripping alarm system that present embodiment provides, the main contacts of circuit breaker DL and auxiliary contact interlock are when the high-tension line dead electricity; The main contacts of circuit breaker DL breaks off; The auxiliary contact of circuit breaker DL are closed, make power supply VC be communicated with the circuit of alarm, and alarm can in time provide the dead electricity alarm; The monitor staff can judge the dead electricity situation of high-tension line quickly and easily, reduces the time of fault recovery.
What should explain at last is: above each embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to aforementioned each embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, perhaps to wherein part or all technical characteristic are equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
