Abstract

The invention provides a transformer substation load switch cabinet with a locking alarm function. The transformer substation load switch cabinet comprises a power distribution cabinet body and a handcart load switch, the power distribution cabinet body is provided with a switch operation area, a voice broadcast device and a controller. A switch static contact is arranged in the switch operation area; the upper end of the switch operation area is provided with an upper baffle plate, and the upper baffle plate is provided with an upper in-place sensor. A lower baffle plate is arranged at the lower end of the switch operation area; a lower in-place sensor is mounted on the lower baffle plate; the handcart load switch is provided with an upper abutting plate and a lower abutting plate. The controller obtains an upper end induction in-place signal inducted by the upper in-place sensor and obtains a lower end induction in-place signal inducted by the lower in-place sensor, and voice broadcasting is carried out through the voice broadcaster to prompt an operator. And in-place switch connection of the transformer substation load switch cabinet is ensured. Influences on normal operation of the switch cabinet caused by improper connection are avoided, and risks and potential safety hazards brought to normal operation of a power system are avoided.

Description

technical field [0001] The invention relates to the technical field of substation maintenance, in particular to a trolley switch isolation baffle blocking alarm device. Background technique [0002] The substation switch adopts the trolley switch. When maintaining and repairing the switch, it is necessary to pull out the trolley switch for maintenance work. After the maintenance is completed, push the trolley switch into the switch cabinet. [0003] At present, when the trolley switch and the switch cabinet are closed, it is easy to cause the connection not to be in place, which affects the normal use of the switch, and also affects the normal operation of the switch cabinet, bringing risks and safety hazards to the normal operation of the power system. SUMMARY OF THE INVENTION [0004] The invention provides a substation load switch cabinet with a blocking alarm function that can improve the connection performance and ensure the stable operation of the power system, com...
