Abstract

The present invention provides a butterfly cover fixing device for transformer gas relay, which comprises a wire wheel central shaft, a wire wheel fixed on the wire wheel central shaft, a knob fixedly connected with the upper end of the wire wheel central shaft, a spring mounting base connected with the wire wheel central shaft through a bearing, two conical springs, two draw wires, two fixing pieces, a screw rod fixedly connected with the lower end of the wire wheel central shaft, a cylinder connected and cooperating with the screw thread of the screw rod and a push rod at the lower end of the screw rod. The two fixing pieces, the two conical springs and the wire wheel are on the same horizontal level. One end of each conical spring is fixedly connected to the spring mounting base while the other end is fixedly connected with the fixing pieces. One end of each draw line is fixedly arranged on the wire wheel while the other end is connected with the other end of each conical spring respectively. The cylinder and the spring mounting base are fixedly connected. The cylinder wall of the cylinder is provided with a hole that allows the push rod to extend beyond. According to the invention, the structure is stable. The device does not come off easily and is convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to the field of electric facilities, in particular to a butterfly cover fixing device for a transformer gas relay. Background technique [0002] Gas relay (also known as gas relay) is a protective device used in transformers, which is installed between the oil conservator and the oil tank of the transformer. When the insulation breakdown, short circuit between turns, the gas generated during the iron core failure or the oil leakage of the oil tank causes the oil level to be too low inside the transformer, the change of the gas volume in the gas relay will cause the change of the position of the float ball, thus touching the light gas The node sends out an alarm signal, and in serious cases sends out a trip signal to cut off the power supply of the transformer. The operation and maintenance personnel can judge whether there is a fault inside the transformer through the state of the gas relay and the oil level reading of the instru...
