Description

Technical Field

[0001] The invention relates to the field of circuit breakers, and in particular to a contact deburring device for a high-voltage circuit breaker. Background Art

[0002] A circuit breaker is a switching device that can close, carry and disconnect current under normal circuit conditions and can close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overloads or short circuits and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to a combination of a fuse-type switch and an over-underheating relay, and generally no parts need to be changed after breaking the fault current.

[0003] The contacts of high-voltage circuit breakers are mainly used in the breaking components of high-voltage circuit breakers. As an important component of the circuit breaker, the main contact system undertakes the main task of conducting current. When the circuit breaker is closed, the main contact system ensures that the current can pass smoothly, thereby ensuring the normal operation of the power system, including conducting current, bearing the system rated current, short-time withstand and peak current, cooperating with the arc contact system, controlling the current transfer time and ensuring the system stability. The realization of these functions is of great significance to ensuring the normal operation of the power system and protecting power equipment from damage.

[0004] Based on the existing technology, in the production process of plum blossom contacts of high-voltage circuit breakers, it is necessary to clean the burrs on the edges of the contacts to ensure that the surface of the contacts is smooth, which is convenient for the subsequent surface silver plating of the contacts. At the same time, during the working process of the contacts, it is necessary to prevent the occurrence of discharge at the contact tip due to the presence of burrs. However, based on the contact deburring method in the existing technology, in the process of deburring the plum blossom contacts, most of them use abrasives to vibrate and tumble grind the contacts to remove the burrs. The burrs on the edges of the contacts are not completely removed, and manual grinding is required later, which has low practicality. Summary of the invention
