Description
Technical Field
The utility model relates to a circuit breaker technical field, concretely relates to intelligent universal circuit breaker static contact assembly.
Background
At present, a universal circuit breaker is also called a frame type circuit breaker, and is a mechanical switch electrical appliance which can connect, bear and break current under normal circuit conditions, and can also connect, bear and break current for a certain time under specified abnormal circuit conditions. Conventional circuit breakers are used to distribute electrical energy and to protect lines and power equipment from overloads, undervoltages, short circuits, etc. The structure of current universal circuit breaker static contact assembly is components of a whole that can function independently overlap joint formula or vertical L type integral type structure, and components of a whole that can function independently overlap joint formula structure is because there is great contact resistance in the faying surface, and the circuit breaker temperature rise is not ideal, causes the circuit breaker to use unstable scheduling problem. The vertical L-shaped integrated structure avoids the heating problem caused by contact resistance, but because the vertical L-shaped structure is close to the arc striking plate, eddy current is easy to generate heat on the arc striking plate, and because of the action of electromagnetic force, the arc striking effect is influenced, thereby influencing the reliability of the circuit breaker.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, the convenient intelligent universal circuit breaker static contact assembly of assembly.
For realizing the above-mentioned purpose, the utility model discloses an intelligent universal circuit breaker static contact assembly, including electrically conductive piece, run-on plate, stationary contact, the one end of electrically conductive piece have the connecting portion of extending outside the circuit breaker bottom plate, the other end of electrically conductive piece fixed part of connection on the circuit breaker bottom plate has, stationary contact set up to serve at one of fixed part, the one end of run-on plate connect and serve at one of fixed part, the other end of run-on plate connect on the circuit breaker bottom plate, fixed part one side of run-on plate on be provided with first inclined plane, second inclined plane respectively, and the interval between first inclined plane and the run-on plate is greater than the interval between second inclined plane and the run-on plate.
The beneficial effect of above-mentioned structure is: the conducting piece is provided with a first inclined plane and a second inclined plane, and a larger space is formed between the arc striking plate and the conducting piece for heat dissipation. The eddy current heat generating effect of the arc striking plate is weakened, and the influence of the conductive piece on the electromagnetic force generated by the electric arc on the arc striking effect is weakened or avoided, so that the temperature rise of the circuit breaker is reduced, and the breaking capacity of the circuit breaker is improved. The upper end of the arc striking plate is connected to the circuit breaker bottom plate, the upper end of the arc striking plate is not contacted with the conductive piece, and a conductive loop cannot be formed, so that the arc striking plate cannot generate heat, the arc striking effect cannot be influenced, and the reliable operation and breaking of the circuit breaker are guaranteed. Therefore, the intelligent universal circuit breaker static contact has the advantages of simple structure, stable and reliable performance and convenient and fast assembly.
Particularly, the fixing part is provided with three fixing holes which are distributed in a triangular shape, and each fixing hole is internally provided with a screw connected with the floor of the circuit breaker. The conductive piece is fixed on the circuit breaker bottom plate through three screws which are arranged in a triangular shape, so that the installation stability of the conductive piece and the circuit breaker bottom plate is ensured.
