Abstract
The utility model relates to a heat conducting device for a vacuum circuit breaker, which is mainly used for the emission of a plurality of heat generated by the work of a moving and a static contacts of a vacuum circuit breaker with high-current, etc. The utility model is composed of a heat pipe (3) which is inserted into an axial center blind hole of a static conducting rod Conductive rod (4) and radiating fins (2) sheathed on the upper part of the heat pipe. The emission of the heat generated in the vacuum arc-extinguishing chamber is quick, timely in time and high-efficiency, so that the utility model can ensure the temperature-rise requirement of the moving conducting rod Conductive rod from a product with high-current capacity.
Description
The utility model belongs to the power switch parts, is mainly used in contact heat radiation in the vacuum interrupter of high current vacuum circuit breaker.
Vacuum circuit-breaker can produce main a large amount of heat between the dynamic and static contact in the vacuum interrupter when work.The upper and lower outlet that the big heat that produces between the existing dynamic and static contact of vacuum circuit-breaker mainly stretches out part outside the vacuum interrupter by dynamic and static contact and has radiator shape and a function is distributed.This for the product of general current capacity still can, but current capacity is reached product more than the 4000A, will make the temperature rise of moving conductive rod surpass national standard.If at this moment still adopt above-mentioned radiator structure, just has only the volume that strengthens the associated metal heat sink.And increase piece volumes is impossible sometimes; Even may, also will cause the increase of the entire product volume, weight and the consumptive material that are difficult to accept.
The design's purpose is exactly to distribute the problem that structure and efficient are not suitable for the high current capacity product needed for solving heat between the dynamic and static contact of switchgear such as existing vacuum circuit-breaker, provides a kind of and leads efficiently, heat dissipation design.
" the vacuum circuit-breaker heat-transfer device " that the design provides is a kind of brand-new structure: be made up of heat pipe in the axial centre blind hole that is inserted in static conductive rod and the fin that is enclosed within heat pipe top.
Wherein the insertion portion surface of heat pipe will be done closely to contact to greatest extent with the static conductive rod blind hole.The fin on heat pipe top can be radially radial arranging, and also can be axial stratiform and arranges.The shape of fin and quantity can make it be full of or exceed the former space in the outlet heat radiation frame of going up.
Operation principle of the present utility model is: utilize the heat pipe of being made up of easy gasifying liquid medium of copper pipe and copper pipe inside and capillary materials with high-efficiency heat conduction performance, the heat in the static conductive rod is conducted out, the fin on heat pipe distributes.
Obviously, utilize the efficient heat-conductive characteristic of heat pipe, this device has fast, in time, heat conduction advantage efficiently, can spread out of a large amount of heat that produces when dynamic and static contact contacts in the high current capacity product vacuum interrupter rapidly, very reduce the temperature rise of moving conductive rod effectively, even current capacity reaches 4000～6000A, the moving conductive rod temperature rise is also in the national standard allowed band.
Below in conjunction with description of drawings embodiment of the present utility model.
Fig. 1 is for having the vacuum circuit-breaker product figure of the utility model " vacuum circuit-breaker heat-transfer device ".
In Fig. 1,1 is last outlet (band radiator structure), and 2 is fin, and 3 is heat pipe, and 4 is static conductive rod, and 5 is vacuum interrupter, and 6 is the following outlet that links to each other with moving conductive rod.As seen from the figure, top has the axially heat pipe 3 of the radial fin of arranging 2, be inserted in its Lower Half in the axial centre blind hole of static conductive rod 4 and and do closely to contact with blind hole, utilize the excellent heat conductivity performance of heat pipe, can be rapidly, in time, efficiently heat is derived and is dissipated, like this, needn't increase dynamic/static contact, conducting rod and other associated components sizes, just can satisfy the heat radiation requirement of 4000A to 6000A high current capacity.
The utility model has been manufactured experimently out sample and test and on probation on vacuum circuit-breaker, shows that this device radiation effect is splendid, can satisfy the temperature rise requirement of the product moving conductive rod of 4000A to 6000A high current capacity fully.
