Abstract
The utility model discloses a 2500A fixing-sealing terminal post, which comprises a terminal post epoxy resin shell body, a vacuum arc extinguish chamber and an upper contact arm, wherein the vacuum arc extinguish chamber is arranged in the epoxy resin shell body, and the upper contact arm is embedded in the epoxy resin shell body. The 2500A fixing-sealing terminal post is characterized in that the rear end surface of the upper contact arm and an upper arc-shaped outer wall of the upper contact wall are provided with radiating fins, wherein the radiating fins are cast with a radiating fin epoxy resin insulating shell body, and the radiating fin epoxy resin insulating shell body and the terminal post epoxy resin shell body are an integrated structure which is formed through once casting. A heat dissipation channel is arranged in the terminal post epoxy resin shell body. The 2500A fixing-sealing terminal post has the advantages that the heat dissipation is excellent, the cooling speed is rapid, the work operation is steady, and the safety performance is high.
Description
Technical field
The utility model relates to a kind of switch cubicle accessory, specifically relates to a kind of great-current fixed sealed pole.
Background technology
High-pressure vacuum breaker has been widely used in the switch cubicle, the vacuum circuit-breaker major loop mainly is made up of conduction major loop and operating mechanism, the conduction major loop develops into pole fixed sealing type structure from unenclosed construction at present, this structure is vacuum not to be had arc chamber and insulating cylinder is integrated into an overall structure, and by embedded technology vacuum is not had arc chamber and be cast in the epoxy resin, make the naked leakage conductance electricity of vacuum interrupter parts to external insulation.But produce a large amount of heats for high current vacuum circuit breaker with pole galvanic circle in running, destroy insulation system, reduce the useful life of circuit breaker, even cause the galvanic circle to be opened circuit, security incident occurs.
The utility model content
The purpose of this utility model provides a kind of perfect heat-dissipating, the pole that usage safety performance is high.
The technical scheme that adopts is:
A kind of 2500A pole, comprise housing and be arranged on housing interior vacuum interrupter and last contact arm, housing is the epoxy resins insulation housing, last contact arm is inner to be connected with the quiet end of vacuum extinction, its technical essential is: upward be connected with fin on half outer wall of contact arm, this fin seals admittedly with epoxy resin, and with the epoxy resins insulation shell body of last contact arm be one-time formed overall structure.
In housing, offer heat dissipation channel.
The utility model has the advantages that heat radiation is good, cooling rate is fast, and it is stable to work, the security performance height.Because in the time of in the utility model is installed in switch cubicle, on the one hand when big electric current such as 2500A electric current enter pole by last contact arm, can produce a large amount of heats, the heat that last contact arm produces is shed by fin, and when the induced draft fan that is provided with in switch cubicle was on the other hand worked, cold air entered the heat dissipation channel in the pole, the heat that produces in the pole housing, the heats cold air, heated air is discharged from heat dissipation channel outlet, guarantees that vacuum interrupter works under the works fine environment.
