Abstract
The utility model discloses a natural air cooling 15kV indoor high voltage vacuum generator circuit breaker. An operating mechanism is fixedly connected with an upper outgoing line end and a lower outgoing line end through insulating supporting pieces, and is connected with a moving contact of a vacuum arc extinction chamber through an insulating tension pole, and the upper outgoing line end and the lower outgoing line end respectively comprise a conductive element and a cooling fin assembled together. According to the circuit breaker, the conductive area is enlarged, the conductive resistance is reduced, the heat productivity of the circuit breaker during a running process is reduced, the surface cooling area is enlarged, and the atmospheric condition is improved; and simultaneously, the cooling fins are not participated in positioning and cooperation, so that the production cost is saved, and the product quality is improved.
Description
Technical field
The utility model relates to a kind of indoor high-voltage vacuum generator circuit breaker.
Background technology
Existing generator circuit breaker product, when operating current is above by 4000A, primary conductive part is because of there being the resistance existence, can produce a large amount of heats, primary conductive spare temperature is raise, because heating increases, heat radiation is slow, the air blast cooling mode that must adopt forced draft fan, air exhauster to combine, because of limited by the air blast cooling component reliability, the circuit breaker temperature rise phenomenon that exceeds standard often takes place in the product running, the safe operation of generator contactor equipment is brought hidden danger.。Circuit breaker is the copper material casting processing with big electric current support now, has complex structure, and difficulty of processing is very big, and casting accuracy is low, and percent defective, the high problem of cost are subjected to structural limitations support area of dissipation can not reach natural air cooled heat radiation requirement simultaneously.
Summary of the invention
For solving the problems referred to above that prior art exists, the utility model provides a kind of natural air cooled 15kV indoor high-voltage vacuum generator circuit breaker, and its technical scheme of taking is:
This circuit breaker comprises operating mechanism, insulated support, vacuum interrupter, insulated tension pole, goes up leading-out terminal and lower wire end, operating mechanism is fixedlyed connected with lower wire end with last leading-out terminal respectively by insulated support, operating mechanism is by the moving contact of insulated tension pole connection vacuum interrupter, and last leading-out terminal and lower wire end are made up of electric-conductor that is bolted together and fin respectively.
The upper and lower leading-out terminal of this circuit breaker has adopted the structural design of brand-new split mounting type, the current-carrying part of upper and lower leading-out terminal and radiator portion are separated design, the remaining space that can make full use of vacuum circuit-breaker has carried out adding macrostructure, both sides all are designed to the fin form, so that give full play to the function of its heat radiation, above improvement had both increased conductive area, reduced conductive resistance, reduce the caloric value in the circuit breaker running, increased the surface radiating area again, improved ventilation condition.Radiator portion is not participated in the location and is cooperated simultaneously, has both saved production cost, again the product quality of Ti Gaoing.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, last leading-out terminal 5 and lower wire end 6 are made up of electric-conductor 7 that is bolted together and fin 8 respectively, operating mechanism 1 is fixedlyed connected with the electric-conductor 7 of last leading-out terminal 5 and lower wire end 6 respectively by insulated support 2, and operating mechanism 1 connects the moving contact of vacuum interrupter 3 by insulated tension pole 4.The thick silver-plated flat copper coin of the double-deck 20mm of outlet side electric-conductor 7 usefulness, do not participate in the strutting piece 2 of conduction and use aluminum component, fin 8 is all used aluminum casting, and strutting piece 7 and electric-conductor 8 are bolted together, fin 8 can be installed at last, gives full play to the function of its heat radiation.
Operating mechanism 1 drives insulated tension pole 4 motions, drives the moving contact motion of vacuum interrupter 3, makes contacting of moving contact and fixed contact, and vacuum circuit-breaker is finished combined floodgate.Operating mechanism 1 drives the motion of insulated tension pole 4 reversings of motion, drives the moving contact motion of vacuum interrupter 3, makes separating of moving contact and fixed contact, and vacuum circuit-breaker is finished separating brake.
