Embodiment
[0019] refer to Figure 1-3 , a power cabinet line overheating and overcurrent protection device, including a control box 1, the inner top of the control box 1 is fixed with a wiring electromagnet 2, and the bottom of the wiring electromagnet 2 is connected with an adsorption plate 4 through a limit spring 3, and the adsorption plate 4 Because the metal plate is subjected to the magnetic force of the wiring electromagnet 2, the bottom of the adsorption plate 4 is fixed with a connecting rod 5, and the inner bottom of the control box 1 is provided with a power switch 6, which is composed of a power connection plate 61 and an overcurrent plate 62. Composed of the overheating plate 63, the connecting plate 61 is fixed to the bottom of the connecting rod 5, the connecting rod 5 is an insulating material, and the connecting plate 61 is electrically isolated from the adsorption plate 4, the overcurrent plate 62 and the overheating plate 63 are respectively connected with the control ...

The invention discloses an overheating and overcurrent protection device for a power cabinet line, which comprises a control box. A wiring electromagnet is fixed to the inner top of the control box. The bottom of the wiring electromagnet is connected with an adsorption plate through a limiting spring; a connecting rod is fixed to the bottom of the adsorption plate, a power connection switch is arranged at the inner bottom of the control box, the power connection switch is composed of a power connection plate, an overcurrent plate and an overheating plate, the power connection plate is fixed tothe bottom of the connecting rod, and the overcurrent plate and the overheating plate are slidably connected with the inner wall of the control box. The overheating and overcurrent protection devicehas the advantages that when the circuit is in an overcurrent state, the wiring electromagnet further attracts the adsorption plate to move, the power connection plate is moved and separated from theovercurrent plate and the overheating plate, so that the power connection switch is disconnected, the whole power connection circuit is disconnected, the circuit damage caused by overcurrent is effectively avoided, and the wiring electromagnet responds at the moment of current increase, so that the power failure is rapid, and the overcurrent damage is further reduced.
Description
technical field [0001] The invention relates to the technical field of power cabinets, in particular to an overheating and overcurrent protection device for circuits in a power cabinet. Background technique [0002] The power cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The power cabinet is used in the occasions where the load is relatively scattered and there are few circuits; In some cases, there are many internal components and complicated circuits; [0003] In order to protect the circuit, the inside of the power cabinet is generally equipped with an overheat protector and an overcurrent protector. The overheat protector is installed in the circuit. When the circuit is overheated, its internal circuit is disconnected, thereby disconnecting the entire circuit to prevent the circuit from overheating and malfunction. , the overcurrent protector is also ins...
