The electric control cabinet can centrally install and control multiple electrical devices, realizing centralized management and control of the equipment. Power-off delay protection is a protection mechanism widely used in power systems. Its main purpose is to provide a period of delayed operation for auxiliary equipment or systems after the main equipment is shut down, so as to ensure the safe shutdown of the equipment or the smooth transition of the system.

[0003] When the main equipment stops, the auxiliary equipment needs to delay working for a period of time to ensure the safety of the equipment or complete necessary subsequent operations. The common power-off delay protection structure is generally fixedly installed somewhere in the electric control cabinet. It cannot be adjusted in position to cooperate with the auxiliary equipment for connection. It is necessary to stretch a long lead inside the electric control cabinet, which is prone to line entanglement. Therefore, an electric control cabinet with power-off delay protection function is needed to solve the above problem. Utility Model Content

[0011] Technical effects and advantages of this utility model:

[0012] (1) This device can limit the adjustment direction of the power-off delay component by setting a lifting guide plate, so that the power-off delay component can be adjusted in the vertical direction. The power-off delay component can be supported by the support component. When the position of the power-off delay component needs to be adjusted, the positioning nut can be removed, the positioning screw can be pulled out, and the position of the U-shaped guide plate can be adjusted to make the power-off delay component close to the auxiliary equipment to be connected. At this time, the support connecting plate is placed directly below the U-shaped guide plate, the positioning screw is inserted into the nearest positioning through hole, and passed through the connecting through hole, the positioning nut is tightened, and the support connecting plate is positioned. The power-off delay component supports, opens the flip connecting plate near the auxiliary equipment, connects the auxiliary equipment wires to the delay relay through the wire slot, and performs power-off extension protection through the power-off delay component. Through the above operation, the power-off delay component and the auxiliary equipment of the electric control cabinet can be connected without adjusting the position of the auxiliary equipment. The auxiliary equipment does not need to stretch long leads and is not easy to be entangled with other lines. This solves the common power-off delay protection structure that is generally fixedly installed somewhere in the electric control cabinet, and its orientation cannot be adjusted to cooperate with the auxiliary equipment for connection. It is necessary to stretch long leads inside the electric control cabinet, which is prone to line entanglement.

[0013] (2) This device can extend the power-off period of the auxiliary equipment by setting a power-off delay component, thereby protecting the internal equipment of the electric control cabinet. The delay relay can switch the power supply of the auxiliary equipment to the backup power supply through the power automatic switching switch after the power is off, and cut off the power after the set delay.
