Abstract
A kind of motor local compensation energy saver, take the mode of local compensation, it is characterized in that: comprise compensatory control cabinet, the inside comprises circuit breaker, contactor, the nearly control device of Capacitor banks, power cable, drop into disconnecting link and circuit breaker, by control device starting contactor reactive power compensator by power cable with need the motor improving power factor in parallel, energy is mutually exchanged between two kinds of loads.Beneficial effect is: for single power consumption equipment, can reduce the starting current of motor; The power loss of distribution system can be reduced; Distribution transformer can be reduced, the reactive current of power distribution network; Improve the power factor of motor; The idle component obtained from electrical network reduces, and which saves electric energy, decreases electricity consumption and drops into.
Description
Technical field
The utility model is applied to that individual motors reactive loss is excessive, and power factor (PF) is on the low side, causes the single motor that energy loss is serious.Local compensation refers to and carries out reactive power compensation in single load-side.
Background technology
Motor belongs to inductive load power supply in running need provide corresponding reactive power to motor, and the reactive power that such motor produces just consumes a part of electric energy, and motor power (output) factor is low, and the idle of consumption will be more.In ac power supply system, most of power consumption equipment belongs to inductive load, needs to set up rotating magnetic field in running, and this part power does not participate in acting, forms reactive power, but it participates in the Energy transfer of power supply.In running, power supply need provide corresponding reactive power to power load, causes line loss to increase, and power delivery active power reduces, power consumption equipment power factor is lower, the reactive power of power delivery is more, and the loss of circuit is larger, and the carrying load ability of power supply is less simultaneously.
Summary of the invention
The purpose of this utility model is: provide a kind of motor local compensation energy saver.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of motor local compensation energy saver, take the mode of local compensation, its feature: comprise compensatory control cabinet, the inside comprises circuit breaker, contactor, the nearly control device of Capacitor banks, power cable, drop into disconnecting link and circuit breaker, by control device starting contactor reactive power compensator by power cable with need the motor improving power factor in parallel, energy is mutually exchanged between two kinds of loads.
The beneficial effects of the utility model are: for single power consumption equipment, can reduce the starting current of motor; The power loss of distribution system can be reduced; Distribution transformer can be reduced, the reactive current of power distribution network; Improve the power factor of motor; The idle component obtained from electrical network reduces, and which saves electric energy, decreases electricity consumption and drops into.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, disconnecting link.2, current transformer.3, circuit breaker.4, contactor.5, reactor.6, capacitor.7, motor
Embodiment
From accompanying drawing 1, the utility model comprises 1, disconnecting link.2, current transformer.3, circuit breaker.4, contactor.5, reactor.6, capacitor.7, motor.8, control device.
Drop into disconnecting link and circuit breaker, by control device starting contactor reactive power compensator by power cable with need the motor improving power factor in parallel, energy is mutually exchanged between two kinds of loads.Like this, the reactive power compensation that the reactive power required for inductive load can be exported by capacitive load.
