Abstract
The utility model discloses an energy-saving motor reactive compensation starting cabinet, which relates to the technical field of motor starting. The energy-saving motor reactive compensation starting cabinet is composed of a circuit-breaking switch, a motor starting device and a capacitor compensation device. A three-phase power source line is connected with the circuit-breaking switch; the motor starting device and the capacitor compensation device are connected in parallel with the circuit-breaking switch; and at least more than one compensation branch and a reactive compensation controller are arranged inside the capacitor compensation device. The energy-saving motor reactive compensation starting cabinet of the utility model can assist in enhancing the stability of a power grid, and enables a motor to continuously work in a stable reactive state without proneness to damaging the lines in the power grid, thereby prolonging the service lives of the lines in the power grid and the motor.
Description
Technical field
The utility model relates to the electric motor starting technical field, relates in particular to a kind of energy-saving electric machine reactive power compensation and starts cabinet.
Background technology
Day by day perfect along with technology, quality to the electrical network electric energy, reduce line loss and become key project of China, the motor that has numerous numbers in the electrical network of China, motor are in operation and self can produce reactive loss and to the loss of circuit, electric current is larger during electric motor starting, electrical network is impacted, to drawing a large amount of reactive capabilities in the electrical network, more increase line loss simultaneously, so the compensation arrangement of motor starting device loading self is particularly important.
Summary of the invention
The utility model is intended to for the deficiency in the background technology, and a kind of energy-saving electric machine reactive power compensation that provides starts cabinet.
Energy-saving electric machine reactive power compensation of the present utility model starts cabinet, to be consisted of by disconnect, motor starting device and power capacitor reactive compensation installation, three-phase power line connects disconnect, motor starting device and power capacitor reactive compensation installation are connected in parallel on the disconnect, wherein are provided with the compensation branch road of one or more in the power capacitor reactive compensation installation and are provided with idle compensating control.
As further improvement of the utility model, described compensation branch road all is connected with three-phase electricity.
Energy-saving electric machine reactive power compensation of the present utility model starts cabinet, has strengthened the stability of electrical network, so that motor continuous firing under a stable idle state is not easy to the damage to power network line, has prolonged the life-span of power network line and motor.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with Fig. 1 the reactive power compensation of the utility model energy-saving electric machine is started cabinet, is described further:
Energy-saving electric machine reactive power compensation of the present utility model starts cabinet, to be consisted of by disconnect 1, motor starting device 2 and power capacitor reactive compensation installation 3, described three-phase power line connects disconnect 1, motor starting device 2 is connected in parallel on the disconnect 1 with power capacitor reactive compensation installation 3, wherein is provided with the compensation branch road 4 of one or more in the power capacitor reactive compensation installation 3 and is provided with idle compensating control 5.Described compensation branch road 4 all is connected with three-phase electricity, on each compensation branch road capacitor group, A.C. contactor and circuit breaker is arranged all.
Electric current is larger during electric motor starting, the needed circuit idle and that bring of motor damages, power capacitor reactive compensation installation 3 provides reactive power compensation to it, reduces the excessive damage to circuit of electric motor starting electric current, and electrical network useful life is provided, electric motor starting is complete, when entering normal operating conditions, reactive requirement weakens gradually, and 5 pairs of reactive power compensations of the idle compensating control in the power capacitor reactive compensation installation are controlled in real time, keep motor under a stable idle state, to work, power supply quality is provided.
