Abstract

The utility model relates to a power-saving reactive compensation control device for circuits, in particular to a reactive compensation control box, including a current transformer (2), a thermal relay (3), an AC contactor (6), a reactive compensate on controller (7), a temperature controller (9), a relay (10), a transformer (11), a small breaker switching capacitor contactor (17) and a capacitor (18). When the reactive compensation control box is in operation, the AC transformer, an air switch, the AC contactor and the thermal relay complete on-off control of the circuit; the reactive compensation controller can not only display real-time voltage, load current, power factor, temperature, harmonic wave percentage and capacitor input of the system, but also make power on-off control, accumulated calculation and reactive compensation of electric equipment with 0-150KVA capacity, thereby efficiently raising the power factor, reducing the loss of electric network and achieving the energy-saving purpose.

Description

The reactive power compensation control cabinet

Technical field:

The utility model relates to the reactive power compensation control device of circuit economize on electricity, especially: the reactive power compensation control cabinet.

Background technology: at present, in the reactive power compensation control device of circuit economize on electricity, except the function of reactive power compensation, the function that does not have other again, therefore in circuit uses, need the metering of other increase needs, from the equipment of functions such as motion tracking, demonstration, therefore improve the production cost of enterprise, increased equipment loss, be unfavorable for environmental protection again.

Summary of the invention:

Goal of the invention of the present utility model is: on the reactive power compensation basis of reactive power compensation control device, having increased power open and close control, electric energy metrical, idle automatic tracking and compensating is the idle compensating control of one, and this idle compensating control can real-time display system voltage, load current, power factor, temperature, percent harmonic, electric capacity input state etc.; To achieve these goals, the utility model is achieved in that the reactive power compensation control cabinet is by binding post, current transformer, thermal relay, insurance, air switch, A.C. contactor, idle compensating control, line bank, temperature controller, relay, transformer, start button, lightning arrester, indicator light, miniature circuit breaker, the three-phase four-wire system active watt-hour meter, switch-capacitor contactor and capacitor are formed, and it is characterized in that: binding post is installed in the front of the electric mounting panel in the reactive power compensation control cabinet, current transformer, thermal relay, insurance, air switch, A.C. contactor, idle compensating control, line bank, temperature controller, relay, transformer and start button; Wherein: current transformer, the thermal relay that is connected with binding post, air switch and A.C. contactor connect with lead; On idle compensating control, utilize lead to connect temperature controller, air switch, relay, transformer and start button respectively by line bank; Reverse side at electric mounting panel is installed miniature circuit breaker, three-phase four-wire system active watt-hour meter and switch-capacitor contactor; In reactive power compensation control cabinet interior lower end lightning arrester, indicator light and capacitor are installed; Wherein: being connected on the capacitor of switch-capacitor contactor and air switch has lightning arrester and indicator light; The three-phase four-wire system active watt-hour meter is connected on the binding post by current transformer.A.C. current instrument transformer, air switch, A.C. contactor and thermal relay are finished the switching control of circuit when using this reactive power compensation control cabinet; The three-phase four-wire system active watt-hour meter of current transformer is finished the meritorious electric quantity metering to power consumption equipment; The control transformer of connecting on the idle compensating control, temperature controller, insurance, thermal relay and capacitor are finished the reactive power compensation of power consumption equipment.This idle compensating control can real-time display system voltage, load current, power factor, temperature, percent harmonic, electric capacity input state etc.; This idle compensating control can be to capacity: the power consumption equipment of 0-150KVA carries out the control of power break-make, accumulation calculating, reactive power compensation, effectively improves power factor, minimizing grid loss, has reached the purpose of economize on electricity.
