Emergency opening/closing operation mechanism of high-voltage switch equipment

Abstract

The invention relates to an emergency opening / closing operation mechanism of high-voltage switch equipment, comprising an opening button, a control button and a closing button on a supporting plate, wherein the control button is connected with a dialing plate; an upper revolving supporting plate is hinged with the supporting plate; an upper revolving shaft is provided with a torsional spring; an upper push rod sleeved with a spring is arranged on an upper end plate of the upper revolving supporting plate and an upper clapboard; when the upper push rod and the opening button are in the same axis, two ends of the upper push rod correspond to the opening button and an opening switch on a breaker panel respectively; a lower revolving supporting plate is hinged with the supporting plate; a lower revolving shaft is provided with a torsional spring; a lower stop pin fixed on the lower revolving shaft corresponds to a lower dialing plate of the dialing plate; a lower push rod sleeved with a spring is arranged on a lower end plate of the lower revolving supporting plate and a lower clapboard; and when the lower push rod and the closing button are in the same axis, two ends of the lower push rod correspond to the closing button and a closing switch on the breaker panel respectively. The emergency opening / closing operation mechanism has a reasonable structure, can completely solve the problem of wrongly touching the opening / closing buttons, and can improve the operation safety.

Description

technical field [0001] The invention relates to an emergency opening and closing operating mechanism of a high-voltage switchgear, and belongs to the technical field of a removable switchgear. Background technique [0002] The high-voltage switchgear is usually composed of a control room, a circuit breaker room, a busbar room and a cable room. A group of static contact seats as a static contact device are fixed in the chamber of the circuit breaker room. The contacts are connected with the external high-voltage power supply circuit. When the circuit breaker chassis trolley is pushed into the circuit breaker room, the upper and lower contacts of the circuit breaker handcart are respectively engaged with the static contacts of the incoming and outgoing lines, and the circuit connection is realized after the circuit breaker is closed. After the circuit breaker manually operates the handcart propulsion mechanism to push the circuit breaker handcart from the test position to the...

Problems solved by technology

But above-mentioned emergency opening and closing mechanism is to be equipped with closing operating lever and opening operating lever respectively on an operating lever support, when rotating runner, operating lever support has only two positions, and a position is closing operating lever and opening operating lever. The opening operating lever rotates with the operating lever bracket and is parallel to the cabinet door. Although the closing button or opening button can be operated, since the closing button or opening button cannot control the closing operating lever and opening operating lever, the circuit breaker cannot be realized. Emergency opening and closing operation of the device; when the operating lever bracket is perpendicular to the cabinet door, the closing button and the opening button correspond to the closing operating lever and the opening operating lever and the cabinet door bracket at the same time, so the closing button or the opening button can be operated The opening button can control the closing operating lever or the opening operating lever, and because it can control the closing operating lever and the opening operating lever at the same time, there will still be accidental button presses, so there are potential accidents
