Embodiment Construction

[0015] A five-proof interlocking mechanism includes a cabinet body 16, an isolation operation shaft 17, a grounding operation shaft 18, a lower door grounding interlocking unit, an isolated load interlocking unit, and an isolated grounding interlocking unit. The lower door grounding interlocking unit includes a lower door interlocking connecting rod 10, a grounding baffle 6, an interlocking connector 9, a lower door interlocking half shaft 7, a lower door locking shaft 12, a crank arm 8, and a hanging door Arm board 11. The door hanging arm plate 11 is connected to the lower end of the lower door interlock connection pull rod 10, and the upper end of the lower door interlock connection pull rod 10 is connected to the interlock connector 9. Door interlock axle 7. The grounding baffle 6 is movably connected to the outside of the front end of the grounding operation shaft 18. When the door-hanging arm plate 11 is not hung on the door, the grounding baffle 6 is blocked in front o...

Abstract

The invention relates to a five-prevention interlocking mechanism, which comprises a lower door ground interlocking unit and a load isolation and ground isolation interlocking unit. The lower door ground interlocking unit consists of a door hanging arm plate, a lower door interlocking connection pull rod, an interlocking connector, a crank arm and a lower door interlocking shaft shaft, wherein the door hanging arm plate is connected with the lower end of the lower door interlocking connection pull rod, the upper end of the lower door interlocking connection pull rod is connected with the interlocking connector, the interlocking connector is connected with one end of the crank arm and the other end of the crank arm is connected with the lower door interlocking half shaft. A ground baffle which is arranged in the front of a ground operating shaft is locked or unlocked under the situation that a lower door is not hung or hung on the door hanging arm plate to control the opening / closing of a ground switch and the opened / locked state of the lower door. The load isolation and ground isolation interlocking unit consists of an isolation indicating wheel, a ground indicating wheel, a cam and a camshaft. After an isolating switch and the ground switch are closed, the ground baffle and an isolating baffle are respectively locked in the front of the ground operating shaft and an isolation operating shaft to prevent the ground switch and the isolating switch from being mistakenly operated. The five-prevention interlocking mechanism has the advantages of small size, convenience in installation, simplicity and convenience in operation and high safety and reliability.

Description

technical field [0001] The invention relates to a high-voltage electrical equipment door lock, in particular to a five-proof interlocking mechanism. Background technique [0002] The power system has always attached great importance to the safe operation of the system, but there will always be various accidents caused by electrical misoperation every year, causing unnecessary losses. In order to effectively prevent personal and major equipment accidents caused by misoperation of operating electrical equipment, my country put forward the requirements of "five preventions" for electrical equipment as early as 1990, and stipulated the management, operation, design and management of misoperation prevention devices in the form of laws and regulations. Principles of use. According to regulations, the design principle of the anti-misoperation device is: all high-voltage electrical equipment that may cause misoperation should be equipped with an anti-misoperation device. [0003] M...
