Abstract
The utility model relates to an outdoor terminal box for a 10kV outdoor breaker, comprising a terminal box (1) and a binding post board (2). The outdoor terminal box is characterized in that: the terminal box (1) is internally provided with a 220v DC intermediate relay (3); one end of a stroke switch ST upon the binding post board (2) is serially connected with the a terminal of the DC intermediate relay (3); the b terminal of the DC intermediate relay (3) is connected with a 220V power supply upon the binding post board (2); the 07-1 open end of a closing loop upon the binding post board (2) is connected with the 1 terminal of the DC intermediate relay (3); and the 07-2 open end of the closing loop upon the binding post board (2) is connected with the 2 terminal of the DC intermediate relay (3). The outdoor terminal box of the utility model adds an intermediate relay based on the original control apparatus, thereby realizing the automation protection function of the breaker closing coil and avoiding the linkage damage to the closing coil resulting from the fault of the energy storage device. The security and reliability of the device is improved by improving the local automation control system of the device.
Description
Technical field
The utility model belongs to power transmission and transformation complex automatic system control device technical field, especially relates to the outdoor circuit breaker control device of a kind of 10kV.
Background technology
At present, the outdoor circuit breaker kind of the 10kV of transformer station is numerous and diverse and part circuit breaker operation year is of a specified duration, and defectives such as circuit breaker energy storage motor, operating mechanism fault or circuit loose contact take place frequently, causes normally energy storage of circuit breaker, and breaker closing is unsuccessful.And because the outdoor circuit breaker automatic control device design of 10kV is perfect inadequately; Circuit breaker is under the situation of normally energy storage; Power supply but continues to cause coil burnout to the closing coil energising, has aggravated the damaged condition of circuit breaker; Raise the greatly spoilage of circuit breaker has reduced power supply reliability.
Summary of the invention
In order to solve circuit breaker under the situation of not energy storage; Power supply but continues to switch on to closing coil; Cause the coil burnout problem, the utility model circuit breaker makes circuit breaker under the situation of not energy storage through adding a kind of control device; Control device cuts off the closing coil power supply automatically, effectively protects closing coil not to be damaged.The utility model solves the technical scheme that its technical problem adopted: according to the substation breakers situation, and design rectification again on the original basis of circuit breaker control device.The direct current auxiliary relay that the choose reasonable control device is required, the layout of arranging outdoor terminal box internal unit again.The outdoor terminal box of the outdoor circuit breaker of this 10kV; Comprise terminal box and connecting terminal block; It is characterized in that being provided with in the terminal box 220V direct current auxiliary relay; The end of travel switch ST on the connecting terminal block and a of direct current auxiliary relay end connect, the b of direct current auxiliary relay hold with connecting terminal block on-the 220V power supply links to each other; The open end of the 07-1 of closing circuit is connected with 1 end of direct current auxiliary relay on the connecting terminal block, and the open end of the 07-2 of closing circuit is connected with 2 ends of direct current auxiliary relay on the connecting terminal block.Wherein a, b terminals are the coil power terminals of auxiliary relay, and 1,2 terminals of auxiliary relay are relay normally open contact.When circuit breaker can not energy storage, the travel switch ST of tank circuit was failure to actuate and is in normally off.During the energy storage locking was closed a floodgate, travel switch ST was in normally open, and the direct current auxiliary relay is failure to actuate, and the 07-1 and the 07-2 of closing circuit are in off-state, had protected closing coil can not burn because of long-term energising.
The beneficial effect of the utility model is; In original control device, add an auxiliary relay; Realize the automation defencive function of breaker closing coil; Avoided causing the chain damage of closing coil, improved local automation's control system of equipment, improved fail safe, the reliability of equipment integral through improvement because of the energy storage device fault.
