Dustproof protective housing of fling-cut switch

Technical Field

The utility model relates to a fling-cut switch technical field specifically indicates a dustproof protective housing of fling-cut switch.

Background

The magnitude of the inrush current is related to the line impedance and the voltage difference between the capacitor and the power supply when the capacitor is switched on. In extreme cases, the inrush current can exceed 100 times the capacitor current rating. Such a large inrush current has a great influence on the lifetime of the capacitor and causes disturbances to the grid, so it is always desirable that the inrush current is as small as possible. In order to reduce the inrush current when the capacitor is put into use, a CJ19 series switching capacitor special contactor, namely a switching switch, is invented, the basic principle of the device is that a current limiting resistor is firstly connected into a circuit to precharge the capacitor, so that the voltage difference between a power supply and the capacitor is reduced, and then the current limiting resistor is short-circuited by a main contact. Such devices can typically reduce the inrush current to less than a factor of 5, but arcing when cutting off the capacitor is unavoidable, so the requirements on the contact are high to ensure adequate service life. However, in the using process, the fling-cut switch is often exposed outside, dust in the air can fall into the fling-cut switch in the using process to influence the use of the fling-cut switch, some existing protective cases cannot relatively seal the fling-cut switch, external dust is still possible to further pollute the fling-cut switch in the protective cases, and meanwhile some protective cases in the market cannot provide a good heat dissipation function for the fling-cut switch at present, and the maintenance is difficult.
