Looped network switch cabinet

Abstract

The invention discloses a looped network switch cabinet, and belongs to the field of high-voltage equipment, and the looped network switch cabinet can realize that when a circuit board is burnt out, a control base makes a response through the induction of a flame inductor, and then the control base drives an electric telescopic rod to press a push plate downwards, so that the push plate slides in a fixed frame and extrudes liquid carbon dioxide, the liquid carbon dioxide is injected into the injection pipeline through a connector, then the liquid carbon dioxide is guided by the spray head to extinguish the position where a circuit of the circuit board is burnt out, and after the spray head sprays out the liquid carbon dioxide to extinguish fire, the spray head can rotate to cover the circuit board, so that the fire extinguishing efficiency is higher; the burnt residual flames are not easy to affect other parts, then a flame sensor is used for sensing and timely feeding back to stop extrusion of the push plate, and in order to reduce the adding frequency of the liquid carbon dioxide in the fixing frame, the push plate extrudes a main balloon to release the liquid carbon dioxide in the main balloon into the fixing frame.

Description

technical field [0001] The invention relates to the field of high-voltage equipment, more specifically, to a ring network switch cabinet. Background technique [0002] The ring network cabinet is a group of high-voltage switchgear installed in the steel plate metal cabinet or made into an assembled spaced ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, low price, and With the advantages of improving power supply parameters and performance and power supply security, it is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. [0003] In the prior art, when the ring main switchgear is in operation, the circuit in it may be burned due to the internal operation overload, and when a fault occurs, it is generally monitored through remote control and an alarm is sent to notify the mainten...
