Abstract
The utility model discloses an indoor high-voltage vacuum circuit breaker totally enclosed solid insulating post with a radiator hood. Except electric connecting end faces of the upper terminal and the lower terminal, outer side surfaces of the upper terminal, the radiator hood, the lower terminal, a vacuum arc-extinguishing chamber coated with a buffer layer and a sealing cover are all coated with epoxy resin layers which enable all the parts to be connected integrally. Compared with the existing indoor high-voltage vacuum circuit breaker posts, the totally enclosed solid insulating post overcomes the shortage that high-voltage live parts of the radiator hoods are exposed. The indoor high-voltage vacuum circuit breaker post is high in insulation property, few in assembling and regulating processes and high in operation reliability, can effectively increase capacity of bearing external environment influence, is assorted and mounted on indoor vacuum circuit breakers of 6-40.5kV, and can be widely applied to high-voltage electric power distribution systems.
Description
Technical field
The utility model relates to electrical equipment technical field, the pole of band heat dissipating housing in especially a kind of indoor high-voltage vacuum circuit breaker.
Background technology
Indoor high-voltage vacuum circuit breaker band heat dissipating housing full-enclosed type solid insulation pole is mainly used on the indoor high-voltage vacuum circuit breaker of 6～40.5kV electric pressure.This indoor HVAC vacuum circuit breaker from last century so far, passed through the improvement of three generation products.The arc control device of first generation vacuum circuit-breaker partly are the open type mounting structure, as the main product ZN2812 type HVAC vacuum circuit breaker before domestic more than ten years, it is because vacuum interrupter and heat dissipating housing directly are open in the air, be subject to the influence of outside air, arc control device are subjected to percussion easily and damage.In order to change this situation, release second generation circuit breaker afterwards, as VS1, VD4 type HVAC vacuum circuit breaker etc., it has adopted the insulated barrel-type mounting structure, vacuum interrupter has been installed in the insulating cylinder, though can avoid some slight bumps, but owing to still adopt air insulation, heat dissipating housing also is to connect by the outside, and the junction also is to expose in air, is subject to the influence of airborne filth, condensation, moisture, dust etc.Present solid sealing type vacuum circuit breaker both domestic and external, VEP just like the Xiamen electric company of China, the 3AH2EP type HVAC vacuum circuit breaker of VD4P type HVAC vacuum circuit breaker of ABB AB and Siemens Company etc.) be third generation product, its phase post adopts the solid encapsulation technique of epoxy resin, admittedly be enclosed in vacuum interrupter in the epoxy resin, can reduce the vacuum extinction chamber enclosure and be subjected to external influence, but because its phase post top heat dissipating housing is a unenclosed construction, heat dissipating housing, high-voltage charged bodies such as arc control device still are exposed in the air, make the charged body insulation against ground of circuit breaker be subject to external environment (as height above sea level, atmospheric pressure and filth, air themperature, humidity, salt fog etc.) influence has reduced the ability that pole conforms.
The utility model content
Problem to be solved in the utility model provides a kind of good insulation preformance, accommodative ability of environment is strong, reliability is high pole.
In order to address the above problem, this indoor high-voltage vacuum circuit breaker pole includes terminals, be contained in the heat dissipating housing on the terminals, following terminals, be coated with the vacuum interrupter of resilient coating and be connected described vacuum interrupter and described down terminals between seal closure these and the identical part of existing indoor high-voltage vacuum circuit breaker pole technical characterictic, in addition, on described, outside the electrical connection end face of following terminals, the described terminals of going up, heat dissipating housing, following terminals, be coated with the vacuum interrupter of resilient coating and the lateral surface of seal closure and all be coated with epoxy resin layer, these parts are linked form an integral body by pouring technology.
In such scheme, described moulding by casting the bottom of described epoxy resin layer, can be one and be shaped to the hollow cylinder that has the shirt rim.
Adopted the indoor high-voltage vacuum circuit breaker pole of technique scheme to compare, had following beneficial effect with existing indoor high-voltage vacuum circuit breaker pole:
1. improved operational reliability.The one, increased the circuit breaker polar area of dissipation, improved the heat dispersion of circuit breaker polar; The 2nd, improved pole surface contamination resistance, guaranteed that the circuit breaker polar electric conductor avoids extraneous environmental impact as height above sea level, atmospheric pressure and filth, air themperature, humidity, salt fog etc., improved the circuit breaker polar electrical insulation properties; The 3rd, strengthened the outer creepage distance of arc control device.Therefore improved the product reliability of operation
2. reduce the circuit breaker assembling and adjusted link.

Fig. 2 is the left view of the utility model embodiment.
Fig. 3 is the cutaway view of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing example the utility model is described specifically:
Fig. 1, Fig. 2 and this indoor high-voltage vacuum circuit breaker pole shown in Figure 3, its heat dissipating housing 1, last terminals 2, be coated with the vacuum interrupter 3 of resilient coating, following terminals 4, be connected seal closure 5 these and the identical parts of existing indoor high-voltage vacuum circuit breaker pole between vacuum interrupter 3 and the following terminals 4, whole lateral surfaces except that the electrical connection end face of last terminals 2 and following terminals 4, all adopt APG technology pouring ladle to be covered with epoxy resin layer 6, it is as a whole that these parts are connected to, wherein the bottom of epoxy resin layer 6 is shaped to the hollow cylinder that has the shirt rim.This indoor high-voltage vacuum circuit breaker pole is fitted in the indoor vacuum circuit-breaker of 6～40.5kV, and its insulation property have the ability of very strong anti-ectocine, and can reduce the debugging work after the assembling.
Claims (2)
1. indoor high-voltage vacuum circuit breaker band heat dissipating housing full-enclosed type solid insulation pole, include terminals, be contained in the heat dissipating housing on the terminals, following terminals, be coated with the vacuum interrupter of resilient coating and be connected described vacuum interrupter and described seal closure between the terminals down, it is characterized in that: except the electrical connection end face of the described electrical connection end face of going up terminals and following terminals, the described terminals of going up, heat dissipating housing, following terminals, the lateral surface of vacuum interrupter and seal closure all is coated with epoxy resin layer, these parts is linked form an integral body.
