Problems solved by technology

[0005] For this reason, the embodiment of the present invention provides an automatic detection and alarm monitoring power distribution cabinet and a line fault judgment method to solve the problem that in the prior art, it is easy to directly determine that the power distribution cabinet line is slightly unstable or abnormal. Faults, resulting in wrong judgments will increase the cost of maintenance and maintenance, and affect the normal operation of the power distribution cabinet

Embodiment 1

[0035] This embodiment provides a monitoring power distribution cabinet with automatic detection and alarm, which generally includes a collection unit arranged in the cabinet body for monitoring the power distribution cabinet line, and a monitoring unit for receiving the monitoring data obtained by the collection unit. A data control system, the control system is connected to the acquisition component by communication, the signal end of the control system is connected to a remote monitoring terminal through a wireless module, and the remote monitoring terminal is connected with a device for performing monitoring when the control system determines that it is abnormal. Alarm module for alarm.

[0036] In this implementation, the data collected by the acquisition component is mainly divided into two categories, one is mainly the data of the distribution cabinet line itself, generally the voltage data and current data of a certain point in the distribution cabinet line, and the oth...

Embodiment 2

[0049] Since the distribution line is composed of various components, the failure, abnormal phenomenon, or instability of each component will cause abnormal or unstable phenomena in the distribution line. However, electronic components and distribution lines have A certain self-recovery performance, especially when there is an unstable phenomenon, does not mean that a certain fault needs to be shut down for maintenance. In the prior art, the judgment of the fault is relatively one-sided. Generally, when there is an abnormal phenomenon in the distribution line, it is directly judged as a fault. , which leads to an increase in the probability of maintenance and overhaul work.

[0050] Such as figure 1 As shown, the present invention provides a line fault judgment method of a power distribution cabinet, comprising the following steps:

[0051] Step 100, at each collection point, use the sampling module to collect the three-phase electric energy data of fundamental wave, harmonic...

Abstract

The embodiment of the invention discloses a monitoring power distribution cabinet for automatically detecting and alarming. A control system processes received monitoring data acquired by an acquisition part according to clock trend, obtains a data sequence, and compares the data sequence with a historical data sequence, so that fault judgement is carried out; a line fault judgment method thereofis mainly as follows: acquired current and voltage of a line of the power distribution cabinet and the temperature of a key point are uniformly interpreted as current data and voltage data; furthermore, historical data, which is obtained before the power distribution cabinet comes into use, is used as the standard; whether real-time updated data of the line of the power distribution cabinet in thecurrent time period fails or not is judged; by means of the method, the self-recovery capability in a condition that the system itself has an instable phenomenon or an abnormal condition can be effectively considered; the system judgement error rate can be reduced; the judgement accuracy rate can be increased; and the overhaul and maintenance cost can be reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of monitoring power distribution cabinets, in particular to a monitoring power distribution cabinet with automatic detection and alarm and a method for judging line faults. Background technique [0002] The power distribution cabinet is one of the important power distribution equipment in the building. The safe and stable operation of the distribution cabinet is directly related to normal production and daily life. When the equipment in the power distribution cabinet is running, it will generate heat due to various reasons, such as surface oxidation, loose connection screws or other reasons that cause heat caused by excessive contact resistance. Usually these heats cannot be observed with the naked eye during operation, and as the temperature gets higher and higher, it will eventually lead to fire accidents. [0003] With the continuous advancement of science and technology, the i...
