Description

Transformer case fault monitoring device Technical Field The utility model relates to the technical field of transformer boxes, in particular to a transformer box fault monitoring device. Background The transformer box is a box body of a place for converting, concentrating and distributing voltage and current of electric energy in the electric power system, and in the use process of the transformer box, in order to ensure the stability of the electric power system and prevent equipment faults, fault monitoring is often required to be carried out on the transformer box. At present, when fault monitoring is carried out on a transformer box, a current transformer, a voltage transformer, a protection relay and a leakage protector are mainly adopted for monitoring protection, however, the following defects exist in the actual use process of the monitoring protection equipment: Although the current transformer, the voltage transformer, the protective relay and the leakage protector can monitor the current and the voltage in the power transformation box, the current transformer, the voltage transformer, the protective relay and the leakage protector can perform power-off protection only after the current or the voltage in the power transformation box exceeds a safety value, so that the monitoring equipment can always monitor and protect after the electric elements in the power transformation box are damaged, and the fault of the power transformation box cannot be monitored and prevented; the cable or the electrical switch in the transformer box is easy to age and wear in the long-time use process, when the cable or the electrical switch ages and wears, the phenomenon of local abnormal overheating occurs, if the cable or the electrical switch is not timely replaced and maintained, the conditions of short circuit, electric leakage and the like can occur, and safety accidents such as fire disaster and the like can also occur when the cable or the electrical switch is serious, and the existing fault monitoring equipment cannot monitor the aging and the wear of the cable or the electrical switch; Therefore, there is an urgent need for a fault monitoring device for a transformer substation that can overcome the above-described drawbacks.
