Detailed Description
According to an embodiment of the invention, an intelligent power distribution room is provided, which comprises a processor, an alarm module and a signal collector;
the signal collector is electrically connected with the processor and is used for measuring the instantaneous signal of the three-phase current of the capacitor at the head end of the distribution room in real time;
the alarm module is electrically connected with the processor and used for sending alarm information;
and the processor is used for calculating the current unbalance degree of the capacitor, controlling the alarm module to send alarm information if the calculated value exceeds a set threshold value, and not sending the alarm information if the calculated value does not exceed the set threshold value.
Preferably, the capacitor current is not balanced
The alarm module comprises an audible and visual alarm arranged in the power distribution room, and further comprises an information transmitter used for transmitting alarm information to workers. Thus, the change of the capacitor current can be predicted in advance, and the occurrence of the capacitor fault can be controlled to a large extent. The connection of each series of capacitance elements in the low-voltage parallel compensation capacitor is delta connection, three electrodes are led out, when the internal elements are broken down by current, the change of voltage caused by circulation current is formed, and an intelligent ammeter and a voltmeter are arranged on each capacitance cabinet. Even if the operating capacitor has excessive overcurrent exceeding the maximum allowable, the on-duty operation and maintenance electrician has a processing time of 2 hours, if the capacitor is quitted from operation within 1 hour, the capacitor is not damaged, which is the processing before the fault, and the capacitor can be continuously put into operation after the fault is relieved.
In at least one embodiment, the information transmitter transmits the alarm information to the staff through short messages or telephone calls or mails or instant messaging software communication modes. The short message mail or instant communication software communication mode can preset the sending content, the content includes the abnormal address, state, time and other factors, and the telephone can also adopt the science university communication flying voice module to broadcast the content telephone to the staff.
In at least one embodiment, the system further comprises a human-computer interaction module for an operator to realize instruction operation and information reading.
In at least one embodiment, the set threshold is 10-20%, specifically, the set threshold may be 10%, 11%, 12%, 15%, 18%, 20%, etc., and the set threshold is 15% in this embodiment.
The invention has better early warning effect on the fault detection of the capacitor and can effectively avoid the fault risk of the capacitor.
The variation in capacitor voltage during operation is typically caused by excessive current flow and current breakdown of the capacitive element. When one phase of the three-phase wiring of the capacitor is in virtual connection, one-phase fuse is fused, an internal angle connection element is broken down and the like, the capacitor can run in a phase-lacking mode, and in order to ensure that reactive power is unchanged, currents of other two phases are increased, namely 'one phase is low and two phases are high'. According to Q ═ 0.24I2Rt it is known that the heat is proportional to the square of the current, which causes the capacitor to generate a large amount of heat over a certain time. This phase-deficient operation is the main cause of the capacitor explosion.
