Description

Substation equipment drainage wire connecting member

technical field

The utility model relates to a connection member for a current drainage wire of a power transformation equipment, which belongs to the field of power equipment tools. the

Background technique

Substation transformers, circuit breakers, voltage transformers, current transformers, metal oxide arresters, isolating switches and many other substation equipment are interconnected through drain wires. If the crimping connection of the drain wires is unreliable, it is easy to generate heat during operation. The heating causes the resistance of the current loop to increase, and the power loss increases during the power transmission process. At the same time, when the heating of the drain wire is serious, the operating temperature of the connected substation equipment will be too high, causing the internal insulating oil of the substation equipment to decompose, reducing the internal temperature of the substation equipment. Insulation performance, in severe cases, even causes short-circuit faults due to insufficient insulation performance of substation equipment, threatening the safe operation of substation equipment. the

Utility model content

In view of this, the purpose of the utility model is to provide a simple structure, easy to use, can effectively realize the reliable connection of the substation equipment drainage wire, ensure that the substation equipment does not heat up, reliable and safe operation of the substation equipment drainage wire connection member. the

The utility model is realized by adopting the following scheme: a connection member for the drainage wire of a substation equipment, which includes a connector, and a pair of bolt holes on the left and the right that go through the upper and lower sides of the connector are provided on the connector, and the bolt holes There are screws inside, the upper side of the connecting piece is provided with a pressing piece fixedly connected to the upper end of the screw, the lower side of the connecting piece is provided with a nut screwed on the lower end of the screw, and the pressing piece is provided with a horizontally penetrating pressing piece. The two ends of the connecting piece are provided with a crimping piece, and the front and rear ends of the crimping piece are provided with through holes, and the through holes are pierced with screws and connected with the corresponding threaded holes Screw fit. the

Further, both ends of the crimping piece are flat, and the middle part is an arc-shaped bulge, and the axis of the arc-shaped bulge is on the same line as the axis of the through hole. the

Compared with the prior art, the utility model has the following beneficial effects: the structure of the connection member of the drainage wire of the substation equipment is simple, convenient to use, and can effectively realize the reliable connection of the drainage wire of the substation equipment, and the connection resistance is small, so that the drainage of the substation equipment The line will not generate heat during operation, ensuring reliable and safe operation of substation equipment without heating, reducing power outage time and power supply load loss. the
