Description
Technical field
The present invention relates to the controlling electric energy field of electric power system, particularly relate to a kind of high-pressure reactive compensation device.
Background technology
The couple capacitors temperature of high-pressure reactive compensation device is more responsive, the operating ambient temperature of capacitor generally with 40 DEG C for the upper limit, can cause shorten the useful life of capacitor when temperature is too high, and capacitor body temperature is too high, also can cause tank of power capacitor pressure increase, often cause tank wall external drum, cause leakage of oil to cause fire or blast.Cross section nargin simultaneously due to the branch bar selection being electrically connected capacitor and high-voltage switch gear is inadequate; Branch bar is oxidized for a long time under outdoor or indoor environment, and resistivity raises; Connect the bolt looseness of busbar, micro-the quivering of busbar causes sparking, particularly connect the reasons such as the bolt looseness of the terminal place bus of capacitor and also easily cause branch bar temperature too high, and the too high capacitor device that also easily causes of branch bar temperature is on fire from explosion.Therefore the temperature of capacitor and branch bar is detected, early warning and control and then to protect this high-pressure reactive compensation device safe operation, eliminate safety hazards be urgent problem.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of high-pressure reactive compensation device.Use this high-pressure reactive compensation device in time to the capacitor of this high-pressure reactive compensation device and the temperature of branch bar detects, early warning and control, can protect this high-pressure reactive compensation device safe operation, eliminate safety hazards.
The technical scheme that the present invention solves the problems of the technologies described above is: a kind of high-pressure reactive compensation device, comprise capacitor and high-voltage switch gear, described capacitor and high-voltage switch gear are electrically connected by branch bar, it is characterized in that: also comprise a capacitor temperature and detect and temperature signal transmission and reception apparatus, described capacitor temperature detects and temperature signal transmission and reception apparatus comprises the temperature detect switch (TDS) inlayed capacitor body both sides and the capacitor temperature logging accepting to send capacitor temperature signal, and this temperature detect switch (TDS) hardwire mode is connected to capacitor temperature logging; Also comprise a branch bar temperature detection and temperature signal transmission and reception apparatus, described branch bar temperature detection and temperature signal transmission and reception apparatus comprise the wireless temperature measurement transmitter module be arranged on branch bar, gather the branch bar temperature polling instrument of the wireless temperature receiver module of branch bar temperature and display branch bar temperature; Also comprise one accept the capacitor temperature signal of capacitor temperature logging transmission and accept capacitor bank protection unit and a voltage and reactive power compensation general controller of the branch bar temperature signal that branch bar temperature polling instrument sends; The switching circuit breaker of described capacitor bank protection unit and voltage and reactive power compensation general controller energy control capacitor and can also alarm signal be sent.
During use, when set point higher than temperature detect switch (TDS) of the capacitor body temperature of this high-pressure reactive compensation device, the dry contact of temperature switch closes, dry contact closed temperature signal reaches capacitor temperature logging, capacitance temperature logging sends early warning signal, and the relay of capacitor temperature logging sends temperature signal to capacitor protection unit and idle compensating control unit simultaneously; Equally, when wireless temperature receiver module collects set point higher than temperature detect switch (TDS) of branch bar temperature signal that the wireless temperature measurement transmitter module be arranged on branch bar sends, the relay of the branch bar temperature polling instrument of display branch bar temperature sends temperature signal to capacitor protection unit and idle compensating control unit; Capacitor bank protection unit and voltage and reactive power compensation general controller send alarm signal and give an order and the switching circuit breaker of capacitor is cut off.
The invention has the beneficial effects as follows: detect and temperature signal transmission and reception apparatus and branch bar temperature detection and temperature signal transmission and reception apparatus, because this high-pressure reactive compensation device also has a capacitor bank protection unit and a voltage and reactive power compensation general controller because this high-pressure reactive compensation device has capacitor temperature.Can in time to the capacitor of this high-pressure reactive compensation device and the temperature of branch bar detects, early warning and control; when set point higher than temperature detect switch (TDS) of capacitor body temperature and branch bar temperature; capacitor bank protection unit and voltage and reactive power compensation general controller send alarm signal and give an order and the switching circuit breaker of capacitor is cut off; thus avoid because of capacitor body and branch bar overheated and cause capacitor to burst, cause the phenomenon of capacitor panel breaking out of fire to occur.Protect this high-pressure reactive compensation device safe operation, eliminate safety hazards.
