Abstract
The utility model discloses a vacuum arc extinguishing chamber capable of improving the external insulation level of the vacuum arc extinguishing chamber, which comprises a vacuum arc extinguishing chamber body. The utility model is characterized in that a room-temperature vulcanized silicone rubber coating is formed on the surface of the vacuum arc extinguishing chamber body. The utility model significantly improves the external insulation level of the vacuum arc extinguishing chamber, enhances the hydrophobicity and the dirt resistance of the vacuum arc extinguishing chamber, and reduces the influence of the external environmental factor on the external insulation level of the vacuum arc extinguishing chamber.
Description
Technical field
The utility model relates to a kind of vacuum interrupter that improves vacuum interrupter exterior insulation level.
Background technology
Vacuum interrupter, have another name called vacuum switch tube, it is the core component of mesohigh power switch, it mainly acts on: make behind the mesohigh circuitry cuts power supply blow-out rapidly and suppress electric current by the good insulating properties of vacuum in managing, avoid accident and unexpected the generation, be mainly used in the power transmission and distribution control system of electric power.The influence that the ceramic package of existing vacuum interrupter is subjected to factors such as wet weather, pollution level easily causes insulation resistance to reduce, and the reduction of exterior insulation level causes phenomenons such as flashover, puncture easily.
The utility model content
The technical problems to be solved in the utility model provides a kind of vacuum interrupter that reduces the raising vacuum interrupter exterior insulation level of extraneous factor influence.
The vacuum interrupter of the improved vacuum interrupter exterior insulation level that the utility model relates to comprises the vacuum interrupter body, and its special character is: be provided with the room temperature vulcanized silicone rubber coating at the vacuum interrupter body surface.
The vacuum interrupter of above-mentioned improved vacuum interrupter exterior insulation level, described room temperature vulcanized silicone rubber coating is the endless belt of width 〉=5mm.
The beneficial effects of the utility model are: by be provided with the room temperature vulcanized silicone rubber coating with good thermal endurance, hydrophobicity, electrical insulating property at the vacuum interrupter body surface, can improve the vacuum interrupter insulation resistance, have protection against the tide, anti-filthy advantage, reduced the influence of extraneous factor to its insulation property, and have excellent physical and mechanical performance, especially on tensile strength, specific elongation and tearing strength, be significantly improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A portion enlarged drawing among Fig. 1.
Among the figure: 1. vacuum interrupter body, 2. room temperature vulcanized silicone rubber coating.
Embodiment
