Starting resistor and switch device integrated with starting resistor

Abstract

The invention provides a starting resistor and a switch device integrated with the starting resistor, the starting resistor comprises a plurality of resistor modules connected in series, each resistor module comprises a grounding sealing cylinder, an inner cavity of each grounding sealing cylinder is an insulating gas filling cavity, and a resistor is installed in each grounding sealing cylinder; the grounding sealing cylinders of the plurality of resistor modules are in butt joint in sequence, the resistors in the adjacent grounding sealing cylinders are connected in series, the grounding sealing cylinders of the resistor modules at the two ends are provided with series connection cylinder openings, basin-type insulators are arranged at the series connection cylinder openings, and the resistors are in conductive connection with middle inserts of the basin-type insulators; the resistor is arranged in the grounding sealing cylinder, insulation between the resistor and the grounding sealing cylinder is ensured by the insulating gas filled in the grounding sealing cylinder, complete insulation of the grounding sealing cylinder is ensured, and the starting resistor is arranged on the ground; the size of the switch equipment is greatly reduced, the occupied area of a direct current field is reduced, the gravity center is lowered, and the anti-seismic performance is improved.
