Background
The relay protection pressing plate is also called a protection connecting plate or a tripping pressing plate, is a bridge and a link of a protection device in connection with external wiring, and is related to the function of protection and whether an action outlet can normally play a role. "power production, safe first", the safe operation of relay protection system is the most important safety guarantee of power system, and the safe operation of relevant equipment in the relay protection system is especially important. Because of the particularity of the relay protection device and other equipment, on a tripping circuit, a 'pressing plate' must be designed, which is an important guarantee means for ensuring the safe operation of the relay protection system, the relay protection pressing plate is a visually visible breaking point, so that an operator can conveniently judge a tripping circuit of the relay protection device and can be communicated with a tripping coil of a switch (breaker), great convenience is provided for maintenance and operation, but a breaking point which cannot be closed completely is added in a protection system of a transformer substation, and due to the particularity of the relay protection tripping pressing plate, two sides cannot be electrified simultaneously in a normal state (without a tripping command). The situations that the relay protection pressing plate is touched by mistake and is moved by mistake during the maintenance of the relay protection equipment are reduced, and the safety during the maintenance of the relay protection equipment is ensured to be the primary task of power production. The existing protective covers are more, but the position of the relay protection pressing plate is relatively fixed and is positioned in a narrow groove, so that the protective covers cannot be completely exposed along with the opening state, and the comprehensive operation is inconvenient.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model aims at providing a protection casing is bumped to relay protection clamp plate maloperation mistake proofing mistake.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a protection casing is bumped to relay protection clamp plate maloperation mistake proofing mistake, set up open-ended protection box and be located protection box gliding relay protection clamp plate fixed plate from top to bottom including the top, the middle part of relay protection clamp plate fixed plate makes progress the arch and forms the boss, the relay protection clamp plate fixed plate surface of boss both sides rotates through the pivot respectively and is fixed with the relative rotatory cover body of opening, and the top lateral wall of every rotatory cover body is fixed with the pull-out handle respectively, the relay protection clamp plate is fixed on the boss, the lower extreme terminal of relay protection clamp plate runs through relay protection clamp plate fixed plate respectively, and the electricity is connected with spiral wiring in relay protection clamp plate fixed plate below.
Furthermore, the top edge of each rotary cover body is respectively provided with a blocking edge protruding out of the rotary cover body, and when the two rotary cover bodies are completely positioned in the protection box, the blocking edges are tightly attached to the top opening edge of the protection box.
Furthermore, each rotating shaft is sleeved with a coil spring, one end of each coil spring is fixed in the relay protection pressing plate fixing plate, the other end of each coil spring is fixedly connected with the cover body, and when the two rotary cover bodies are completely positioned in the protection box, the coil springs are in a compressed state.
Furthermore, the involutory contact edges of the rotating cover body are respectively provided with rubber sealing strips which are clung together.
The utility model has simple structure, when the relay protection pressing plate is not operated, the rotary cover body is directly pushed into the protection box in a closed manner, which is equivalent to the relay protection pressing plate is taken in the protection box, and double-layer protection is formed in the rotary cover body and the protection box, thereby being more beneficial to preventing mistaken touch; when operating the relay protection clamp plate, pull out and open the rotatory cover body and can make the relay protection clamp plate expose externally, through the mode that rises to pull out with the relay protection clamp plate expose externally completely, the rotatory cover body is in the state of opening completely, is more convenient for operate the relay protection clamp plate.
