Abstract
The utility model discloses a loaded switch, namely, a reactive random compensation loaded switch. The utility model is composed of a loaded switch with a reactive compensation device. The utility model has the characteristics of obvious power saving effect and complete safety device.
Description
The utility model relates to a kind of on-load switch, promptly controls the idle random back-off on-load switch of inductive load (motor).
Have in the technology at oneself, the effect of used on-load switch only is the startup of control load and stops, and does not produce power savings; Used reactive power compensator is everlasting and is equipped with in the large-scale control cubicle, promotes the use of to be restricted.
The utility model purpose is to provide a kind of being convenient to promote the use of at above-mentioned deficiency, the significant idle random back-off on-load switch of power savings.
Technical solution of the present utility model is achieved in that idle random back-off on-load switch is made of on-load switch (or A.C. contactor) and the reactive power compensator that has on it.When switch was installed, just the triple line that reactive power compensator is drawn was connected on respectively under the power supply triple line in the line circuit with switch, accomplished to install synchronously with switch, synchronous switching, automatically to the timely reactive power compensation of load.
Advantage of the present utility model and good effect are: 1. be convenient to promote the use of carrying out reactive power compensation with electric loading.Reactive power compensator and switch united two into one install and use,, make in the reactive power compensator Live wires road and extensively promoted the use of as long as just can carry out reactive power compensation on the spot at any time to inductive load with switch.2. use, easy for installation.Reactive power compensator and switch are installed synchronously, synchronous switching, and volume is little, in light weight need not to set up, and uses, installs very convenient.3. improve power factor and reach more than 95%, on average economize on electricity 20%, transformer increase-volume 30-35% reduces line loss, extension lead and electromechanical equipment useful life.4. installation is complete.In put electric installation.Limit the coil excess temperature device that shoves, make the reactive power compensation safe operation reliable.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structure diagram;
Fig. 2 is the utility model circuit theory diagrams.
Referring to Fig. 1, the utility model is made of the reactive power compensator under switch 1 (A.C. contactor) and its base frame 2.
Referring to Fig. 2, switch 1 is connected in the three-phase circuit, and reactive power compensator 2 is connected on A, B, C 3 points in the three-phase circuit that switch rolls off the production line.Reactive power compensator 2 control circuits by capacitor 3, be connected the over-temperature protection device 4 at capacitor 3 two ends and the discharge resistance 5 that is connected across between the capacitor 3 three-phase line ends constitutes.Over-temperature protection device is used to prevent the capacitor overload.Discharge resistance 5 put to safe voltage (below 36 volts) voltage after equipment has a power failure in one minute.
Claims (2)
1. an idle random back-off on-load switch comprises switch (1), it is characterized in that switch (1) has reactive power compensator (2).
2. according to the described idle random back-off on-load switch of claim 1, it is characterized in that described reactive power compensator (2) by non-polar condenser (3), be connected the over-temperature protection device (4) at capacitor (3) two ends and the discharge resistance (5) that is connected across between capacitor (3) the three-phase line end constitutes.
