Title:
STARTER WITHOUT POWER CONSUMPTION OF MOTOR OF COMMERCIAL REFRIGERATION COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2016/119391
Kind Code:
A1
Abstract:
A starter without power consumption of a motor of a commercial refrigeration compressor, comprising a current transformer (L1), an inductor (L2), a two-way thyristor (T), a PTC element and a starting capacitor (C1). An end (1) of a primary coil of the current transformer (L1) and an end of the inductor (L2) are jointly connected to an alternating-current power supply; an end (3) of a secondary coil of the current transformer (L1) is connected to a G electrode of the two-way thyristor (T); the other end (2) of the primary coil and the other end (4) of the secondary coil of the current transformer (L1)are jointly connected to a leading-out end (M) of a primary winding of the motor; the other end of the inductor (L2) is connected to a T1 electrode of the two-way thyristor (T); a T2 electrode of the two-way thyristor (T) is connected to an end of the PTC element; the other end of the PTC element is connected to an end of the starting capacitor (C1); the other end of the starting capacitor (C1) is connected to a leading-out end (S) of an auxiliary winding of the motor. The starter has low power consumption, versatile applicability and good safety.
