Description

Technical Field

[0001] The utility model belongs to the technical field of power equipment, and more specifically, relates to an outdoor high-voltage circuit breaker. Background Art

[0002] Outdoor high-voltage circuit breakers, especially outdoor high-voltage vacuum circuit breakers, are crucial equipment in power systems. Their structural principle is mainly based on vacuum arc extinguishing technology. Existing outdoor high-voltage circuit breakers are generally composed of a vacuum interrupter, a contact system, a spring mechanism, a mechanical transmission system, etc. When the circuit needs to be closed, the worker operates the handle to close the circuit, the spring mechanism releases the stored energy, and the mechanical transmission system makes the moving contact and the static contact contact and fit tightly together to form a conductive path. Once the circuit needs to be disconnected, the mechanical transmission system is controlled by a relay to achieve opening.

[0003] The existing application number is: CN202321369709.X. This utility model discloses an outdoor high-voltage circuit breaker, which relates to the technical field of circuit breakers, including a device body and a protective mechanism. The device body includes a fixed base, the top of which is mounted a circuit breaker body, and the top of which is mounted three terminals. The protective mechanism includes a fixed plate, one side of which is provided with a movable plate, and an inner wall of one side of the fixed plate is provided with a connecting groove, and the inner wall of the connecting groove is provided with a sealing gasket. The utility model allows the protective mechanism to be stably sleeved on the outer side of the circuit breaker terminal through the connection between the clamping groove and the clamping ring. The connection between the fastening bolts and the fixing holes and the mounting holes tightly connects the fixed plate and the movable plate, thereby preventing the protective mechanism from falling off the circuit breaker and allowing staff to easily replace and install the protective mechanism. The sealing gasket can be used to seal the gap between the connecting plate and the connecting groove.

[0004] Based on the above, when opening a high-voltage circuit breaker, a worker is generally required to manually turn the handle. However, since the insulation layer of the circuit breaker is exposed to the outside world for a long time, once the insulation layer is damaged, it is easy for the high-voltage current to pass through the handle when the worker turns the handle and injure the worker, which poses a certain safety hazard.
