Problems solved by technology
In order to reduce the loss of national economy and people's life and property caused by electrical fire accidents, the previous method is to rely on the tripping of circuit breakers or fuses for prevention and control. Problems such as large impact of changes and poor reliability make it difficult to play an effective role in practical applications
The existing electrical fire supplementary prevention and control technology for residual current detection is based on the aggregated amplitude characteristics of residual current for electrical fire detection, and it is difficult to accurately distinguish between evenly distributed residual current (normal operation) and spot heat accumulation residual current (fault ), therefore, there are often false negatives and false negatives

Embodiment Construction
[0008] Such as figure 1 As shown, the multi-circuit fire detection device of the present invention includes an electric circuit A and a fire controller XF. The electric circuit A has six circuits, and the incoming and outgoing terminals of the six electric circuits A are sequentially connected with circuit breakers HD and remaining Both the current detector TC and the residual current detector TC are connected to the fire controller XF by wires.
[0009] Wherein, the residual current detector TC is a HV20020-XF-TC residual current detector, and the fire controller XF is a HV2002D-02 fire controller.
[0010] The present invention utilizes a fire controller, which can continuously and accurately detect the residual current of six circuits at the same time, and then realize the electrical fire caused by faults such as short circuit, overload, three-phase unbalance, and grounding in the six circuits. effective containment and isolation.

The invention relates to a multi-loop fire detection device which comprises at least two electrical circuits A and is characterized in that the device also comprises a fire controller XF. A circuit breaker HD and a residual current detector TC are connected between the wire inlet ends and wire outlet ends of the electrical circuits A. The residual current detector TC is connected to the fire controller XF by using a conductive wire. The multi-loop fire detection device has the advantage of good reliability. By using the detection device, the electric fire detection can be carried out, and missed report and wrong report conditions can be avoided. The device is suitable for detecting the electric fire caused by short circuit, overload, three-phase unbalance, ground and other faults in a low voltage power supply system.
Description
technical field [0001] The invention relates to a detector. Specifically, it is a multi-circuit fire detection device used to detect electrical fires caused by faults such as short circuit, overload, three-phase unbalance, and grounding. Suitable for low voltage power supply system. Background technique [0002] It is well known in the power system that electrical fire accidents often occur in low-voltage power supply systems due to faults such as short-circuit, overload, three-phase imbalance, and grounding, which pose a great threat to the national economy and people's lives and property. In order to reduce the loss of national economy and people's life and property caused by electrical fire accidents, the previous method is to rely on the tripping of circuit breakers or fuses for prevention and control. Problems such as large impact of changes and poor reliability make it difficult to play an effective role in practical applications. The existing electrical fire supple...
