Product Description
Medium voltage dc motor soft starter
Introduction
Wanlida Medium voltage soft starter is applicable to startup of various types of heavy-duty motors ranging from 3 kV to 11 kV, capable of restricting the starting current of heavy-duty motors to 1.5 ~ 4 times their rated current and of effectively controlling the electric grid fluctuation and mechanical wear occurring at startup of heavy-duty motors.
Applications
High-voltage magnetic-control soft starters are applicable to all heavy-duty motors applied in factories and mines.
For example:
Electric power: induced draft fans, fan blowers, desulfurization booster fans, mill fans, and boiler feed pumps etc.
Metallurgical industry: dedusting blowers, exhaust fans, water circulating pumps, and blast furnace blowers etc.
Petrochemical industry: water circulating pumps, compressors and exhaust fans etc.
High performance price ratio
Conservation of electric network volume
Primary switch equipment, transformers and cable shockproof current etc. may create an allowance saving of 50%.
The capital expenditure for power distribution room may be saved by 60%.
Purchase cost of starting equipment may be saved by 70%.
Equipment overhaul/maintenance expenses may be saved by 80%.
Principle
A high-voltage solid-state magnetic control soft starter is composed of inlet wires, switch and medium-voltage controlled reactor, motor and its load. A fail-safe secondary control system is composed of controller, three-phase full wave rectifier and high/low-voltage dual isolators.
In the system of high-voltage solid-state magnetic control soft starter, closed-loop current control is achieved by acquiring primary loop current to adjust the low-voltage control coil so as to change the reactance value of high tension loop of the reactor, such that the motor may be started up smoothly.
Operating principle of controllable reactors
Cores may be expressed by magnetic field lines, and the core status is implemented by the operating points on the magnetic field lines. During actual operation, if the variance in control current is relatively slow while the track far away from the operating points extends through to the zones that are far away from the origin of coordinates. That is exactly the actual operation characteristics of controlled reactor controlled reactor that acts as action element of high-voltage motor soft starter. Actual ideal curves B and H are shown in Fig. 2, in which, basic electromagnetic properties of the core are reserved. The high-voltage winding of each phase contains 2 series-connected coil assemblies, and the induced voltage on the ac winding is proportional to dB Σ/dt. B∑ is the sum of 2 corresponding cores, and it is as shown in Fig. 3 when the magnetic potential of control coil yields Hkwith reverse polarities on the 2 cores. Variance in Hkis relatively slow. In Fig. 3, Hk and Hacare respectively the curves corresponding to the current of control winding and high -voltage working winding. The control winding implements its control over the current of the high-voltage winding just by controlling the heterodromous zones indicated in Fig. 3.
