Description

Technical Field

[0001] The invention belongs to the field of environmental protection gas ring network cabinets with a chain function, in particular to an environmental protection gas ring network cabinet with a chain function. Background Art

[0002] A gas-insulated ring main unit (GIRMU) is a type of high-voltage switchgear used in power distribution systems. It utilizes gas insulation technology, using SF6 gas as the insulating medium, and arc extinguishing technology to achieve compact design and reliable operation of high-voltage equipment. A GIRMU primarily consists of a gas-insulated switchgear, transformer, circuit breaker, load switch, and measuring instruments. It effectively isolates high-voltage equipment from the external environment, providing enhanced safety and reliability. GIRMUs have replaced traditional high-voltage distribution cabinets and are widely used in power equipment.

[0003] Because power distribution cabinets are typically connected to external power lines with high voltages, maintenance operations require disconnecting switches (such as load switches and isolating switches) to cut off power. Failure to do so can be dangerous. To prevent accidental switch operation, a self-locking mechanism is used to lock the electrical components within the ring main cabinet, preventing misoperation and ensuring the safety of construction personnel.

[0004] Traditional interlocking devices can only interlock a row of switches, or all switches, and cannot freely adjust the number of switches that need to be interlocked, making it inconvenient for staff to make flexible adjustments.

[0005] Therefore, we have made improvements to this and proposed an environmentally friendly gas ring network cabinet with interlocking function. Summary of the Invention

[0006] In order to make up for the shortcomings of the existing technology, the problem that the traditional interlocking device can only interlock one row of switches, or interlock all switches, and cannot freely adjust the number of switches that need to be interlocked is solved.

[0012] Furthermore, a spring is provided between the locking block and the fixed plate, and the spring is sleeved on the connecting rod. A circular hole with a radius equal to that of the connecting rod is provided at the center of the locking ring, and a plurality of first sliding grooves are provided in the circular hole of the locking ring. A plurality of second sliding grooves are provided on both sides of the first sliding groove, and the sliding pin is slidably connected to the second sliding groove.

[0013] During operation, the spring is arranged so that the spring forces the locking plug to be close to the switch through elastic force. The sliding pin is slidably connected to the second chute so that the sliding pin can slide in the second chute.

[0014] Furthermore, a plurality of guide blocks are fixedly provided on the top and bottom of the fixed plate, a plurality of first guide grooves are provided on the top and bottom of the second movable plate, a plurality of second guide grooves are provided on the top and bottom of the first movable plate, the guide blocks are slidingly connected to the first guide grooves and the second guide grooves, and two locking pins are symmetrically fixed on one side of the second movable plate close to the fixed plate.

[0015] During operation, the guide block is slidably connected with the first guide groove and the second guide groove, so that the guide block can slide in the first guide groove and the second guide groove.

[0016] Furthermore, the locking pin passes through the outer wall of the fixed plate and extends to the outside, and a number of locking blocks are fixed on both sides of the inner cavity surface of the first movable plate.
