The invention discloses a voltage and current protector with overvoltage protection and a protection system, comprising an insulating plate and a protector. One end of a hydraulic rod is fixedly connected with a positive electrical interface. The invention relates to the technical field of voltage and current protectors. According to the voltage and current protector with overvoltage protection and the protection system, the middle of the top of the insulating plate is fixedly connected with the bottom of the protector, and the protector includes a current detection module and a voltage detection module. When overvoltage occurs, surrounding workers can be warned immediately that the protector has started overvoltage protection. The whole process of overvoltage protection will be carried out under the monitoring of workers, and many accidents can be avoided. When the protection system cannot be used in case of emergency, manual protection can be performed immediately. The protector andthe protection system are easy for people to use. The problem that the existing voltage and current protector with overvoltage protection cannot remind the staff in time in case of overvoltage is solved.
Description
technical field [0001] The invention relates to the technical field of voltage and current protectors, in particular to a voltage and current protector with overvoltage protection and a protection system. Background technique [0002] Overvoltage protection refers to a protection method that disconnects the power supply or reduces the voltage of the controlled equipment when the voltage of the protected line exceeds the predetermined maximum value. Both equipment and household appliances have a rated voltage, and the voltage range is usually specified as 170V-240V. If the voltage exceeds this value, the insulation strength and withstand voltage value of the appliance will be exceeded, and the appliance will heat up, break down, burn out or even catch fire. At present, due to the theft of neutral wires, equipment aging, technical failures, human failures, natural disasters, power outages, and other reasons, the voltage is unstable, the voltage is too high or too low, and a la...
