An alarm system for high and low voltage power equipment

Abstract

The invention discloses an alarm system for high and low voltage power equipment, which belongs to the technical field of fire alarming for power equipment, and comprises a high and low voltage power cabinet. The left and right sides of the high and low voltage power cabinet are provided with vents, and the two vents are The interior of the cabinet is fixedly equipped with dust-proof nets, and the left and right sides of the interior of the high and low voltage power cabinet are slidingly connected with support plates. In this invention, the smoke is detected by the smoke alarm, and the fire alarm transmits fire information to the outside. The two vents are closed, so that the device can exhaust the inside of the high and low voltage power cabinet through the exhaust fan, and then quickly remove the open fire inside the device, and the fire extinguishing dry powder can be sprayed in the elastic airbag, so as to achieve the purpose of rapid fire extinguishing, so that the device can be quickly extinguished. The fire extinguishing effect is better, so that when a fire occurs in a short circuit, the fire can be quickly extinguished.

Description

technical field [0001] The invention relates to the technical field of fire alarming for electric equipment, and more specifically, relates to an alarm system for high and low voltage electric equipment. Background technique [0002] As the name implies, the high and low voltage power distribution cabinet is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high-voltage switchgear, and then step down the low-voltage side through transformers. It leads to the low-voltage power distribution cabinet, the low-voltage power distribution cabinet and then to the power distribution boards, control boxes, and switch boxes. Inside are protective devices such as switches, circuit breakers, fuses, buttons, indicators, meters, and wires. A device that is assembled into a power distribution device that meets the design function requirements. [0003] With the...

AI Technical Summary

Problems solved by technology

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide an alarm system for high and low voltage power equipment, which has a better fire extinguishing effect, so that when a fire occurs in a short circuit, the fire can be quickly extinguished, increasing the safety of the device. And the device has an alarm effect, the staff can quickly deal with the aftermath, and avoid the occurrence of secondary fires. It solves the problem that a fire may occur after a short circuit occurs in the electrical equipment. Strong short circuit, it is not suitable to use conventional methods for fire extinguishing, resulting in relatively average self-rescue ability of power equipment, unable to quickly and timely extinguish fire of power equipment, and the warning and alarm effect of the device is relatively not good enough
