Outdoor primary and secondary fusion isolation knife built-in intelligent post switch

Abstract

The invention discloses an outdoor primary and secondary fusion isolation knife built-in intelligent post switch, which comprises an aluminum alloy base and an aluminum alloy housing matched with thealuminum alloy base, The aluminum alloy housing is fastened on the aluminum alloy base to form an outer enclosure box, a plurality of isolation knife main circuit driving structures are arranged in the outer enclosure box, 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 inner end of the outer enclosure is provided with a hollow chamber, A power operating mechanism is installed in the hollow chamber, The power operation mechanism comprises a front panel and a rear panel, a component mounting chamber is formed between the front panel and the rear panel, and an isolation power mechanism for controlling the separation knife to separate and close, a circuit breaker power mechanism for controlling the circuit breaker to be on and off, and a circuit breaker closing energy storage mechanism for circuit breaker to be on and off for energy storage are installed in the component mounting chamber; The whole power operation mechanism can provide power source to the circuit breaker and the isolating knife separately or simultaneously.

Description

technical field [0001] The invention belongs to the technical field of on-pole switches, in particular to an outdoor smart on-pole switch with a built-in primary and secondary fusion isolation knife. 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, compat...
