Description

Electric tracing power supply box with fault indicator lamp and electric tracing power supply device Technical Field The utility model relates to the technical field of electric tracing systems, in particular to an electric tracing power supply box with a fault indicator lamp and an electric tracing power supply device. Background The electric tracing system is widely applied to the antifreezing heat preservation of equipment such as pipelines, storage tanks and the like. The conventional electric tracing power supply box generally only comprises a circuit breaker and a power interface, and when the circuit breaker is tripped due to overload, short circuit or electric leakage, an operator needs to manually check the state of the circuit breaker, and cannot quickly locate faults, so that the maintenance efficiency is low. The prior art lacks an integrated, visual fault indication scheme. Disclosure of utility model The utility model provides an electric tracing power supply box with a fault indicator lamp and an electric tracing power supply device, aiming at solving one or more of the technical problems in the prior art. The technical scheme includes that the electric tracing power supply box with the fault indicator comprises a box body, a box cover and the fault indicator, wherein the box cover can be buckled on the open end of the box body in an adaptive mode, the fault indicator is embedded on the side wall of the box body, a plurality of wiring terminals are fixed on the inner side face of the bottom wall of the box body, and a live wire and a zero wire of the fault indicator are respectively connected with two different wiring terminals.
