Problems solved by technology
[0003] In some cases, the voltage of the line increases suddenly and exceeds the rated voltage of the electrical equipment. If the power cannot be cut off in time, the electrical equipment will be damaged.
[0004] In the electrical equipment in the prior art, the power line is usually connected to the power supply line in the line. When the voltage unexpectedly increases significantly, the connection between the power line and the power supply line cannot be disconnected in time, which may easily cause damage to the electrical equipment. bring loss to people

The invention discloses a self-disconnecting emergency protection device for electrical equipment, which belongs to the technical field of electrical equipment. Through the setting of overvoltage strain rods, when the line voltage suddenly increases greatly, the overvoltage strain rods can be used in the external electric field. Automatic extension under the action, thereby driving the separation of the left connecting plug and the right connecting plug, and then automatically disconnecting the connection between the power supply line and the power supply line to prevent damage to electrical equipment, and through the setting of the instantaneous hard anti-coupling ball, the left connecting plug , When the right connecting plug is separated, it can drive the instantaneous hard anti-coupling ball to produce irreversible deformation, so that when the overvoltage strain rod recovers, it cannot drive the left connecting plug and the right connecting plug to re-insert, which can further prevent electrical equipment from being damaged. , Second, it can win sufficient maintenance time for maintenance personnel, and there is a split ball group, which can provide an additional driving force to accelerate the separation between the left connecting plug and the right connecting plug, and further improve the protection effect.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, and more specifically relates to a self-disconnecting emergency protection device for electrical equipment. Background technique [0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. The important role played by electricity in our life and production cannot be ignored. It brings us great convenience and becomes an important energy source in our production and life. The most critical element in a power plant for the proper operation and delivery of electricity is the electrical equipment. [0003] In some cases, the voltage of the line increases suddenly and exceeds the rated voltage of the electrical equipment. If the power-off treatment cannot be performed in time, the electrical equipment will be damaged. [0004] In the electrical equipment in the prior art, the power line is usually c...
