Problems solved by technology

[0002] In the battery pack running in the substation of the power system, it is easy for the battery to break away from the busbar. This fault will lead to the state of the backup power supply of the battery pack out of control, and the monitoring dead zone of the detection system. Such accidents have occurred frequently in recent years.
In the prior art, there is a detection device for the working state of the battery, but it is not mainly aimed at the detection of the main fuse of the battery and the open circuit state, and the detection of the state of the fuse becomes a detection blind spot

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing:

[0030] Such as figure 1 As shown, the battery pack main fuse blown and open circuit detection device includes a power parameter detection device and a control logic device, the control logic device is connected to the power parameter detection device; the power parameter detection device has a voltage detection device and a current detection device The four voltage detection interfaces of the voltage detection device are respectively connected to the detection points on both sides of the positive fuse and the negative fuse, and the current detection interface is connected to the loop current detection point to detect the voltage and voltage on both sides of the main fuse connecting the battery pack to the bus. The loop current of the battery pack; the control logic device judges whether the main fuse of the battery pack is blown and the open circuit of the battery pack occu...

Abstract

The invention relates to the technical field of storage battery, and more specifically, relates to a main fuse fusing and open-circuit detection method and apparatus for a storage battery pack. The main fuse fusing and open-circuit detection method and apparatus for a storage battery pack can monitor the storage battery state in a transformer station, and can quickly detect and determine the result and generate an alarm signal when the storage battery is separated from a bus, thus being convenient for maintenance for the staff, and guaranteeing safety of the standby power supply of the transformer station.

Description

technical field [0001] The present invention relates to the field of storage battery technology, and more specifically, to a method and device for detecting blown and open circuit of a main fuse of a storage battery pack. Background technique [0002] In the battery pack running in the substation of the power system, it is easy for the battery to break away from the busbar. This fault will lead to the state of the backup power supply of the battery pack out of control, and the monitoring dead zone of the detection system. Such accidents have occurred frequently in recent years. In the prior art, there is a detection device for the working state of the battery, but it is not mainly for the detection of the battery main fuse and the open circuit state, and the detection of the state of the fuse becomes a detection blind spot. Therefore, it is necessary to study the main fuse of the battery pack and the open circuit judgment method, and directly apply it to the stable and safe ...
