The invention discloses a voltage and current protector with overvoltage protection and a protection system, including an insulating plate and a protector, and 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. The voltage and current protector and protection system with overvoltage protection are fixedly connected to the bottom of the protector through the middle part of the top of the edge plate. The protector includes a current detection module and a voltage detection module, which can immediately monitor the surrounding work when overvoltage The personnel will give a warning, prompting that the protector has started overvoltage protection. At this time, the entire overvoltage protection process will be carried out under the supervision of workers, which avoids many accidents. When the emergency protection system cannot be used, it can be manually activated immediately. protection, which is beneficial to people's use, which solves the problem that the current existing voltage and current protectors with overvoltage protection cannot remind staff in time when overvoltage and other situations occur.
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 a predetermined maximum value. Equipment or household appliances have a rated voltage, and the voltage range is usually specified as 170V-240V. If this voltage is exceeded, the dielectric strength and withstand voltage of the electrical appliance will be exceeded, and the electrical appliance will heat up, break down, burn out or even catch fire. At present, due to the theft of zero line, aging equipment, technical failure, man-made failure, natural disaster, power outage and re-powering, etc., the voltage is unstable, the voltage is too high or too low, and a la...
