A built-in isolating knife structure for outdoor intelligent post switch

Abstract

The invention discloses a built-in isolating knife structure for an outdoor intelligent post switch, which comprises an aluminum alloy base and an aluminum alloy housing matched with the aluminum alloy base, The aluminum alloy housing is fastened on the aluminum alloy base to form the outer enclosure box, A plurality of isolate knife main circuit drive structure is arranged in parallel and in series in the outer enclosure box, A left outlet terminal is arranged at that left end of the driving structure of the isolate knife main circuit, a right outlet terminal is arranged at the right end of the driving structure of the isolating knife main circuit, a left voltage sensor and a right voltage sensor are arranged on the driving structure of the isolating knife main circuit, a left current sensor is arranged at the inner end of the left outlet terminal, and a right current sensor is arranged at the inner end of the right outlet terminal; The outer enclosure box and the insulation box are arranged in two layers, and the whole structure is box-type, with built-in isolation knife and voltage / current sensor; the main drive is linearized; the electric field strength is uniform; the arc extinguishing chamber adopts vacuum arc extinguishing chamber; and the insulation medium adopts environment-friendly gas insulation.

Description

technical field [0001] The invention belongs to the technical field of pole switches, in particular to a built-in isolation knife structure for an outdoor intelligent pole switch. Background technique [0002] At present, the outdoor pole-mounted switches are mainly ZW32, ZW20, and FZW28 types, of which ZW32 and ZW20 are outdoor pole-mounted circuit breakers with external isolating knife; FZW28 is an outdoor load switch with built-in isolating knife. The above-mentioned pole-mounted switch is a primary device in the distribution network, which directly acts on the transmission line. In order to make the distribution network work better, it needs to be equipped with monitoring equipment, control equipment, etc., and these devices are called secondary equipment. Although the combination of these primary devices and secondary devices can realize intelligent power distribution through modern technology, but the interface between devices does not match, compatibility, scalability...
