Abstract
The utility model provides a high voltage vacuum contactor with a composite insulating arc blowout chamber. An insulating protecting sleeve with an umbrella skirt is arranged on an outer shell of the vacuum arc-extinguishing chamber; an adhesive layer is arranged between the outer shell and the protecting sleeve for connecting. Thereby, the insulating pressure resistant capability, dirt resistant capability and moisture resistant capability of a vacuum contactor are conspicuously increased; simultaneously, the damage of the arc-extinguishing chamber caused by external force can be advided. The utility model is suitable for somewhat adverse environments with much powder dust, high moist, mud, mine with a plurality of rain, oil field with a plurality of rain, etc.
Description
The utility model belongs to insulation protecting device, particularly a kind of high-pressure vacuum contactor with compound inslation arc control device.
Be used for controlling high-tension line, transformer, high-voltage motor.The unlatching of capacitor group, can realize the high-pressure vacuum contactor of far distance automatic controlling, the serviceability of its critical piece arc control device plays crucial effects in equipment, it not only will possess higher breaking capacity, higher dielectric voltage withstand level, also to possess dustproof moisture resistance, make in its suitable various environment and use.And its structure of the arc control device in original vacuum contactor is only to be provided with glass shell or alumina ceramic shell at arc control device internal structure skin, in use its defective is: the outer creepage distance of one is little, withstand voltage level is low, arc control device turnover line end is withstand voltage poor mostly, and withstand voltage level reduces especially greatly in many dirt wet environment; Its two easily generation collision cleft damage, causing arc control device to be scrapped can not use.
The purpose of this utility model provides a kind of high-pressure vacuum contactor with compound inslation arc control device, it has overcome above-mentioned defective effectively, makes the dielectric voltage withstand performance of contactor, and anti-soil is dirty, the wet ability of moisture resistance significantly improves, and has stopped the damage of external force to arc control device simultaneously.
The utility model is realized with following technical scheme for achieving the above object: a kind of high-pressure vacuum contactor with compound inslation arc control device, vacuum interrupter with glass or alumina ceramic shell, it is characterized in that: on its shell, be provided with insulating sheath with full skirt, and the adhesive layer that has one deck that it is connected between the two between shell and the protective jacket.
Above-mentioned insulating sheath is to be made by silicon rubber.
Characteristics of the present utility model are: adopt the utility model to change serviceability: one can improve breaking capacity, and breaking current is 16 times of volume electric current to the maximum, is higher than the index of standard GB 14808 (10 times); It two has improved the dielectric voltage withstand level, has strengthened along surperficial creep distance, makes that power-frequency voltage all is higher than 14,808 two times of phase voltage indexs the highest of standard GB between the arc control device fracture; The wet ability of the dirty moisture resistance of its three anti-soil significantly improves, and has stopped the damage of external force to arc control device simultaneously.
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
Accompanying drawing 1 structural representation of the present utility model.
Among the figure: 1 arc control device, 2 shells, 3 protective jackets, 4 adhesive layers.
As Fig. 1: on the glass of arc control device 1 or alumina ceramic shell 2, make silicon rubber insulation protective jacket 3 earlier with full skirt by sealant adhesive layer 4 bonding giving.
The utility model is particularly suitable for many dust, and is high moist, cement, and the mine, oil field and rainy water etc. are than using in the adverse circumstances.
