Abstract
The utility model provides a high voltage vacuum contactor with separating units, which belongs to a high voltage contacting apparatus. The utility model is composed of a vacuum arc-extinguishing chamber, a regulating part, and an electromagnetic system, wherein, the vacuum arc-extinguishing chamber and the regulating part are installed in separating units which are formed by that DMC insulating materials are pressed; the electromagnetic system is connected in series with a holding coil which keeps attracting; the connection between the vacuum arc-extinguishing chamber and the electromagnetic system takes advantage of a bell crank with the ration of 1: 2; so each of the separating units can be fixed on the electromagnetic system; the number of the units is changed, and the utility model can be combined into 10KV high voltage vacuum contactors with various specifications, such as three pole, four pole, five pole, etc. The utility model has the advantages that the break of arcs is small, the utility model can prevent damp, the utility model can resist the high voltage, the consumption of energy is small, and the utility model is suitable for frequent operation under the condition of large loads.
Description
The utility model relates to a kind of high voltage connector, and it is widely used in controller switching equipment, on the industrial power-equipment.
Domestic high voltage connector is a kind of A.C. contactor of air type 10KV high pressure at present, and it is bigger that this contactor cut-offs electric arc, and coefficient of safety is little, and volume is big, can not satisfy user's requirement.Along with the straight empty contactor of another kind, get final product the generation of the vacuum contactor of multipole combination, it is big to have overcome volume, cut-off the bigger shortcoming of electric arc, but this vacuum contactor meeting moisture absorption, insulating properties reduces, can not bear the high pressure of 10KV, be not suitable for environment and badly reach the heavier occasion of load.
The purpose of this utility model is the vacuum contactor that a kind of high pressure resistant protection against the tide will be provided, and it can effectively prevent arcing phenomena, and can be under the condition of bigger load frequent operation.
The purpose of this utility model is achieved in that and adopts high-tension circuit and low-voltage circuit arrangement up and down, by vacuum interrupter, electromagnetic system, adjusting portion is grouped into, vacuum interrupter and adjusting portion are divided in an insulating cover, promptly in isolated location, again each isolated location is fixed on above the electromagnetic system, connection between electromagnetic system and the vacuum interrupter is to finish by means of 1: 2 bell crank lever, electromagnetic system is by two series coils, the iron stamen, armature is formed, energy consumption when being kept by hold-in winding restriction adhesive, electromagnetic system adopts the direct current making electromagnet.
The ripple porcelain tube that the arc control device shell adopts 95 porcelain insulating materials to make, contact material is selected Cu_W_WC for use.
Isolated location is made up of housing and chassis, and housing and chassis are made by the DMC insulating material.
Advantage of the present utility model: dielectric property height, anti-electric leakage, humidity resistance excellence, mechanical strength is good; It is little to consume energy, and does not have arcing phenomena, safe and reliable; Simple in structure, be easy to assembling.
Description of drawings;
Fig. 1 is the configuration diagram with high-pressure vacuum contactor of isolated location;
Fig. 2 is the high-pressure vacuum contactor 220V circuit theory diagrams with isolated location.
Below in conjunction with Fig. 1 _ 2 working condition of the present utility model is described:
The utility model mainly is made up of vacuum interrupter (5), electromagnetic system (10), adjusting part (8).Vacuum interrupter (5), adjusting part (8) are contained in a high voltage bearing insulating cover (11) jointly, promptly in isolated location, insulating cover (11) is made up of housing (14) and chassis (9), be connected be flexible coupling (7) between the moving guide rod (6) of vacuum interrupter (5) and lower wire end (1), constitute the path of main circuit.Insulation adjustment disk (2) couples together moving guide rod (6) and driving mechanism, and insulation against ground, by the embedded nut in chassis (9) chassis (9) is twisted with this isolated location and other isolated location to lump together again.Connection between vacuum interrupter (5) and the electromagnetic system (10) is that the bell crank lever (4) by means of 1: 2 is finished, and the bell crank lever of employing 12 connects, and the action arm of force is longer, helps satisfying the requirement of horizontal separating brake.Electromagnetic system adopts the direct current making electromagnet, electromagnet revolution square shaft (3) drives the vacuum interrupter moving contact and carries out deciliter action, the electromagnetic system combined floodgate initial stage applies full voltage, and closing a floodgate is over is kept by the hold-in winding that seals in (12) adhesive in pull-in winding, makes energy consumption drop to minimum point.This machine has rectifier bridge (13), can supply alternating current operation, like this, each isolated location is fixed on above the electromagnetic system (10),, just can forms the 10KV high-pressure vacuum contactor of plurality of specifications such as three utmost points, four utmost points, five utmost points as long as change the quantity of isolated location, this high voltage connector adopts the isolated location of novel DMC insulating material compacting, the good creepage distance of humidity resistance is big, has improved proof voltage and mechanical strength, for the miniaturization of this machine lays the foundation.
Claims (2)
1, the high-pressure vacuum contactor that has isolated location, by vacuum interrupter (5), electromagnetic system (10), adjusting part (8) are formed, it is characterized in that: vacuum interrupter (5), adjusting part (8) are contained in an insulating cover (11) by housing (14) and chassis (9) formation, be in the isolated location, again each isolated location is fixed on above the electromagnetic system (10), electromagnetic system adopts and to seal in hold-in winding (12) and carry out adhesive and keep, the connection between electromagnetic system and the vacuum interrupter by means of 1: 2 bell crank lever (4) finish.
2, the high-pressure vacuum contactor with isolated location according to claim 1 is characterized in that the housing (14) of insulating cover and chassis (9) are made by the DMC insulating material.
