Abstract
The utility model relates to a heavy-current embedded pole for an indoor high-voltage vacuum circuit breaker. The heavy-current embedded pole comprises an epoxy resin insulating casing, a vacuum arc-extinguishing chamber and an upper contact arm, wherein the vacuum air-extinguishing chamber and the upper contact arm are both packaged in the epoxy resin insulating casing, and the rear end of the upper contact arm is connected with a fixed end of the vacuum arc-extinguishing chamber. The heavy-current embedded pole is characterized in that a conductive clip with a radiating fin is mounted at a movable end of the vacuum arc-extinguishing chamber (3), a contact arm radiating fin is mounted at the rear end of the upper contact arm, the upper contact arm is a hollow contact arm, and a vent passage is arranged in the epoxy resin insulating casing. Heat can be dissipated by the contact arm radiating fin as soon as possible. When the heavy-current embedded pole used as an accessory is sleeved in a switch cabinet, cold air enters the pole under action of an induced draft fan in the switch cabinet, and heat from the radiating fin on the conductive clip and the contact radiating fin can be dissipated out of the pole quickly via the vent passage, so that the service life of the embedded pole is prolonged and safety thereof is increased.
Description
Technical field
The utility model relates to a kind of accessory of high voltage electric power equip ment, particularly relates to the great-current fixed sealed pole of 4000A that a kind of high-pressure vacuum breaker is used.
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 is at the above-mentioned problems in the prior art, provides a kind of indoor high-voltage vacuum circuit breaker with excellent heat dispersion performance great-current fixed sealed pole.
The technical scheme that adopts is:
The great-current fixed sealed pole of a kind of indoor high-voltage vacuum circuit breaker, comprise the epoxy resins insulation housing and be encapsulated in epoxy resins insulation housing interior vacuum interrupter and last contact arm, the rear end of last contact arm is connected with the quiet end of vacuum interrupter, it is characterized in that described vacuum interrupter moved end is equiped with flange-cooled conductive clip, is equiped with the contact arm fin in last contact arm rear end;
Above-mentioned last contact arm is hollow contact arm;
In the above-mentioned epoxy resins insulation housing, offer air duct.
Be provided with air duct in the pole, when great-current fixed sealed pole of the present utility model is set in switch cubicle as accessory, under the effect of the induced draft fan in switch cubicle, cold air enters in the pole, discharge the heat that the fin on the conductive clip and contact fin distribute outside the pole rapidly through heat dissipation channel, in addition owing to adopt the hollow contact arm of going up, the heat that big electric current produces during through last contact arm, a part sheds by the contact arm fin, another part is discharged through the heat dissipation channel of hollow contact arm, by above-mentioned good radiator structure under above-mentioned induced draft fan effect, radiating and cooling is effective, thereby has improved the useful life and the security performance of pole.
