Abstract
The utility model discloses a discharge device for a capacitor, comprising an alternating current power supply, a circuit breaker, a time relay and a discharge circuit. The circuit breaker, time relay and discharge circuit connected in series through a wire are connected with the alternating current power supply. The utility model is convenient to operate, safe and reliable and can protect the capacitor.
Description
Technical field
The utility model belongs to power supply unit repair and maintenance instrument, especially relates to a kind of discharge device of a capacitor.
Background technology
Increase along with social power load; The capacity of transforming plant main transformer depressor also constantly increases in the electric power system; The increase of main transformer capacity, according to the regulation of electric power system, the power capacitor capacity in the reactive power compensator will satisfy the requirement of main transformer capacity 10%～15%; Therefore the power capacitor capacity of transformer station is also in continuous increase, to satisfy the requirement of system to reactive power compensation.
Power capacitor is in operation and carries reactive power to electric power system; When it is out of service owing to itself have the characteristics of store electrical energy; Lean on self with voltage transformer discharge; So that when moving next time, be unlikely to because the voltage stack causes capacitor by high electrical breakdown, therefore, stopping transport at capacitor must not be less than 10 minute to putting into operation the midfeather time once more.Because the current protection of capacitor is to lean on fuse protectedly, if fuse failure, capacitor is connected with the voltage transformer disconnection, can't self-discharge, and at this moment just need operating personnel to go to the scene and manually discharge.At present, discharging rod is mainly adopted in the discharge work of 10KV capacitor, and discharge operation is lack of standardization, and there is great potential safety hazard in personal safety.
Summary of the invention
For addressing the above problem, the purpose of the utility model provides a kind of easy to operate, safe and reliable discharge device of a capacitor.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of discharge device of a capacitor, it comprises DC power supply, circuit breaker, the time relay and discharge circuit, circuit breaker, the time relay and discharge circuit through after the lead series connection, are connected with DC power supply successively.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This discharge device of a capacitor, it links to each other with capacitor through discharge circuit, can realize the capacitor discharge, has reduced labor intensity of operating personnel, and is easy to operate, safe and reliable, reaches the purpose of capacitor for voltage protection.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Through accompanying drawing and embodiment the utility model is done further explain below.
As shown in Figure 1; This discharge device of a capacitor, it comprises DC power supply, circuit breaker, the time relay and discharge circuit, circuit breaker, the time relay and discharge circuit are successively through after the lead series connection; Be connected with DC power supply, DC power supply adopts the 220V DC power supply; Circuit breaker is assisted normally opened contact one termination dc power anode, and the other end links to each other with the coil of the time relay, and the normally opened contact of the time relay is connected with discharge circuit, and the output of discharge circuit links to each other with dc power cathode, power cathode ground connection.
When capacitor is discharged, the input of discharge circuit is connect the capacitor high-pressure side through lead; Make breaker closing, the auxiliary normally opened contact of circuit breaker is closed, and the coil of the time relay gets electric, trigger, and after time-delay a period of time, the normally opened contact of the time relay is closed, and discharging circuit conduction begins capacitor is carried out discharge work.
