High-low voltage electric cabinet

Abstract

The invention discloses a high-low voltage electric cabinet, which comprises a cabinet body. An electric appliance cavity with a forward opening is formed in the cabinet body, four protection boxes arranged in a rectangular mode are arranged on the rear wall of the electric appliance cavity, and a temperature sensing device capable of sensing the temperature of the protection boxes and cooling the protection boxes is arranged above the protection boxes. A pop-up device for quickly popping up the protection box when an electric appliance in the protection box is on fire is arranged behind the protection box, a folding door device capable of being tightly closed is arranged in the falling channel, and a fire extinguishing device capable of pumping out air to extinguish fire is arranged in the fire extinguishing cavity. The high-low voltage electric cabinet is provided with a temperature sensing device, can regulate and control the temperature in the protection box, is provided with a pop-up device capable of quickly pushing the protection box with internal electric appliances on fire away from the cabinet body to fall into the fire extinguishing cavity, is further provided with a folding door device capable of isolating the fire extinguishing cavity from the electric appliance cavity, and is further provided with a fire extinguishing device capable of pumping away air in the fire extinguishing cavity.

Description

technical field [0001] The invention relates to the field of high and low voltage cabinets, in particular to a high and low voltage cabinet. Background technique [0002] The reliability and safety of power equipment is very important. As the final equipment of the power supply system, the high and low voltage cabinets are of great significance to the safe operation of the entire power supply system. During long-term use, the high and low voltage cabinets may Due to the aging of equipment and lines, short circuit between points, etc., the circuit or electrical components in the cabinet will catch fire, causing a fire accident and causing the paralysis of the power supply system. If the fire extinguishing treatment cannot be carried out in time, it will cause major economic losses Loss, more serious may cause casualties, is not conducive to people's use, and the fire is often because a single electrical component catches fire, because it cannot be quickly isolated, the entire...
