Abstract
The invention discloses a heat dissipation device for a drawout breaker. The heat dissipation device is installed on a plurality of buses led out of the breaker. The buses are led out of the breaker horizontally or perpendicularly. The heat dissipation device comprises a plurality of cooling devices which are arranged on the buses respectively. Each cooling device comprises a cooling base and a plurality of cooling fins perpendicularly arranged on the cooling base at intervals, wherein an installation hole is formed in the cooling base, and the surface of each cooling fin is a polished surface. By means of the heat dissipation device, the heat dissipation surface area of the buses is enlarged; in this way, the heat dissipating temperature rise of the bus ends can be greatly dispersed through the cooling devices, and the technical requirement for lowering the temperature rise of the drawout breaker can be met; the heat dissipation device is simple in structure, convenient to install, safe and reliable.
Description
Technical field
The present invention relates to electric equipment field of radiating, particularly a kind of heat abstractor for drawout breaker.
Background technology
When drawout breaker works in the energized state, the conducting element of live part can generate heat under current vortex and the effect of conducting element electrical impedance, so increasing drawout breaker conducting element cooling surface area is one of key technology reducing drawout breaker temperature rise.In prior art, usually adopt the surface area increasing drawout breaker outlet bus to solve the technical problem of circuit breaker temperature rise, but the consumption of outlet bus copper certainly will be increased like this, the manufacturing cost of drawout breaker can be increased so widely.
Summary of the invention
The object of this invention is to provide a kind of heat abstractor for drawout breaker, increase bus cooling surface area, the heating temperature rise of such bus end is dispersed widely by radiator, reach the technical requirement reducing drawout breaker temperature rise, and structure is simple, easy for installation, and safe and reliable.
In order to realize above object, the present invention is achieved by the following technical solutions:
For a heat abstractor for drawout breaker, it is arranged on the some buses of extraction of circuit breaker, and described bus level or vertically draw from circuit breaker, be characterized in, this heat abstractor comprises several radiators, and it is separately positioned on bus.
Described radiator comprises radiating seat, interval vertical is arranged on some fin on radiating seat;
