Abstract

The invention relates to a load fuse wire detecting device and a power system. The load fuse wire detecting device comprises a fuse wire state detecting module and an alarming module. The fuse wire state detecting module comprises a state detecting unit and an auxiliary power supply, the state detecting unit is used for detecting whether a corresponding fuse wire is disconnected or not, and the auxiliary power supply is used for guaranteeing the state detecting unit to work normally when the corresponding fuse wire is not disconnected. The alarming module is used for sending alarming signals according to the detecting result of the state detecting unit. The invention further relates to the power system. The fuse wire detecting device and the power system enable the compatibility of the fuse wire detecting device to be strong and improve the using efficiency of the power system through the arrangement of the state detecting unit and the auxiliary power supply.

Description

technical field [0001] The invention relates to the field of circuit detection, in particular to a load fuse detection device and a power supply system with strong compatibility and energy saving. Background technique [0002] Existing power systems are provided with corresponding load fuses to protect the power system and corresponding loads. In a general power supply system, a load fuse is connected in series between the negative pole of the load and the power supply, and a load fuse detection device is also provided in the power supply system to detect the state of the load fuse. The structural diagram of this power supply system and load fuse detection device is as follows: figure 1 and figure 2 as shown, figure 1 is a schematic structural diagram of an existing power supply system, figure 2 It is a structural schematic diagram of the first embodiment of the existing load fuse detection device. Among them, Bus+ is the positive pole of the power supply, Bus- is the...
