Abstract
The utility model relates to a fast switching capacitor box, which comprises a casing, a reactive power automatic compensation controller module, a current transformer module, a voltage transformer module and a plurality of capacitor compensation return circuits. One ends of the current transformer module and the voltage transformer module are connected with a bus, and the other ends of the current transformer module and the voltage transformer module are connected with an input end of the reactive power automatic compensation controller module. A control end of the reactive power automatic compensation controller module is connected with control ends of a plurality of silicon-controlled switch modules, one end of each silicon-controlled switch module is connected with the bus through an automatic switch and a knife switch, and the other end of each silicon-controlled switch module is connected with one capacitor compensation return circuit. The silicon-controlled switch modules have the advantages of contactless control, fast reaction speed, long service life and good reliability and do not generate sparks, so that switching on and off of the capacitor compensation return circuits can be finished fast.
Description
Technical field
The utility model belongs to the capacitor compensation cabinet technical field, especially a kind of quick switching capacitance cabinet.
Background technology
Capacitor box is the reactive power compensating apparatus of using always; Its structure is: comprise housing, reactive power self-compensating controlling device module, current transformer module, voltage transformer module, relay module and a plurality of capacitance compensations loop; One end connection bus of current transformer module and voltage transformer module; Current transformer module is connected the input of reactive power self-compensating controlling device module with the other end of voltage transformer module; The control end of reactive power self-compensating controlling device module connects an end of relay module, and the other end of relay module connects the A.C. contactor module in a plurality of capacitance compensations loop respectively.The action of reactive power automatic compensation control module control relay module realizes the input and the excision in capacitance compensation loop thus.Because the reaction speed of relay module is slower, so its inapplicable as these frequent startings of electric welding machine, the load use that stops.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of simple in structure, quick switching capacitance cabinet that production efficiency is high is provided.
The technical scheme that the utility model is taked is:
A kind of quick switching capacitance cabinet; Comprise housing, reactive power self-compensating controlling device module, current transformer module, voltage transformer module and a plurality of capacitance compensations loop; One end connection bus of current transformer module and voltage transformer module; Current transformer module is connected the input of reactive power self-compensating controlling device module with the other end of voltage transformer module; It is characterized in that: the control end of reactive power self-compensating controlling device module connects the control end of a plurality of reverse-blocking tetrode thyristor modules; All through an automatic switch and a knife switch connection bus, the other end of each reverse-blocking tetrode thyristor module all connects a capacitance compensation loop to one end of each reverse-blocking tetrode thyristor module.
And, series reactor module between said reverse-blocking tetrode thyristor module and the capacitance compensation loop.
And, lightning arrester connected in parallel module between said each knife switch and the automatic switch.
The advantage and the good effect of the utility model are:
In the utility model; The control end of reactive power self-compensating controlling device module connects the control end of a plurality of reverse-blocking tetrode thyristor modules; Because the reverse-blocking tetrode thyristor module has contactless control, reaction speed is fast, the life-span is long, the advantage of good reliability; Do not have spark and produce, the input in capacitance compensation loop and excision are accomplished rapidly, guaranteed compensation like the reactive power of these frequent startings of electric welding machine, the load that stops.
