High pressure intelligent synthesis starting cabinet

Abstract

The invention relates to a high-voltage intelligent integrated starting box, which belongs to the field of high-voltage switch box and starting box technology, mainly solves the prior problems due to the separation of high-voltage switch box and starting box such as non-ideal switching, starting and even operating of a motor, complex operation and unstable effect. The high-voltage intelligent integrated starting box is characterized in comprising a box body, a water resisting box, a polar plate box, an isolation switch, a high-voltage vacuum contactor, a current transformer and a lightning arrester, a transmission motor and a transmission mechanism therein provided, wherein the isolation switch, the high-voltage vacuum contactor, a current transformer, the lightning arrester, a light resistor and a short-circuit contactor are electrically connected with each other to form a main circuit; the starting box further includes a control circuit for controlling the high-voltage switch and a low-voltage liquid resistor; Two isolated chambers of high-voltage and low-voltage are arranged in the upper part of the box body; and the isolation switch is disposed in the high-voltage chamber. The invention has the advantages of good starting effect, stable and convenient operation and less space, and can be widely used in metallurgic industry, building materials, chemical engineering industry, electric industry, etc.

Description

technical field [0001] The invention belongs to the technical field of high-voltage switch cabinets and starting cabinets, and in particular relates to a high-voltage intelligent comprehensive starting cabinet for switching and starting control of high-voltage winding motors and cage motors. Background technique [0002] At present, the devices used for switching and starting high-voltage wound motors or cage motors are separate high-voltage switch cabinets and starter cabinets. The high-voltage switchgear is composed of a cabinet body, an isolation switch, a high-voltage vacuum contactor, a current transformer, an arrester and a high-voltage switch control circuit. Among them, the high-voltage switch control circuit consists of a main circuit and a current detection circuit, a voltage protection circuit, and an overcurrent protection circuit. , power supply indication circuit, vacuum contactor control circuit, closing indication circuit, opening indication circuit, overcurr...

AI Technical Summary

Problems solved by technology

Due to the separation of the high-voltage switchgear and the starting cabinet, when controlling the same motor, it is easy to cause unsatisfactory operation of the switch, start and even the motor, the operation is cumbersome, the effect is unstable, and it is especially easy to cause unfavorable factors such as impacting the power grid.

In addition, the use of two cabinets still has the disadvantages of taking up a lot of space and having one more set of cabinet materials.
