Problems solved by technology

[0003] The existing intelligent medium-voltage switchgear includes a low-voltage instrument room, a bus room, a circuit breaker and a connector room, and a cable room. During use, the bus components in the bus room are arranged linearly, and the distance between the bus bars is small, which increases leakage SF6 gas is used for insulating and filling. SF6 is easy to decompose at high temperature to form toxic gas. During maintenance, it is easy to cause injury to the staff. At the same time, the insulation performance of the vacuum phase column in the circuit breaker room is poor. , in the case of electric leakage, the whole does not have the function of preventing false touch alarm, and the risk factor is relatively large

Abstract

The invention discloses an insulation protection device for an intelligent medium-voltage switch cabinet capable of preventing mistaken touch. A body shell comprises a low-voltage instrument chamber, a bus chamber, a circuit breaker and connector chamber, and a cable chamber. The device is characterized in that a bus assembly is cast on the inner wall of the bus chamber in an insulating manner; the bus chamber and the circuit breaker and connector chamber are filled with insulating gas used for insulation; an insulating gas filling device is arranged on the left side of the body shell; and an alarm module used for preventing mistaken touch and electric leakage alarm is arranged on the left side of the body shell. According to the invention, buses in the bus chamber are circularly arranged, so that the distance between the buses is increased, and the insulation performance is enhanced; nitrogen is adopted as the insulating gas and is recyclable while having an insulation effect, and the cost is reduced; insulating umbrella skirts and epoxy resin pouring shielding covers are arranged in vacuum phase columns, and the insulation performance is improved; and under the condition of electric leakage, a warning function is realized through the alarm module.

Description

technical field [0001] The invention relates to the technical field of intelligent medium-voltage switchgear, in particular to an insulating protection device for intelligent medium-voltage switchgear that can prevent false touches. Background technique [0002] Traditional medium-voltage switchgear is a complete set of electrical appliances with switches as the main body. It is mainly composed of several main parts such as circuit breakers, transformers, secondary control and protection circuits, instruments, and isolating switches. , the user does not care about the performance of the switchgear itself. [0003] The existing intelligent medium-voltage switchgear includes a low-voltage instrument room, a bus room, a circuit breaker and a connector room, and a cable room. During use, the bus components in the bus room are arranged linearly, and the distance between the bus bars is small, which increases leakage SF6 gas is used for insulating and filling. SF6 is easy to deco...
