Abstract

The invention discloses a super-efficient double voltage motor factory test circuit. The super-efficient double voltage motor factory test circuit comprises a factory test table, a three-phase induction regulator, a breaker and an alternating current contactor, and is characterized in that the three-phase induction regulator is connected with the factory test table and a breaker (QS) in series, a wire outlet end of the three-phase induction regulator is connected with a connecting terminal of a motor and a wire inlet end of an alternating current contactor (KM1), and a wire outlet end of the alternating current contactor (KM1) is connected with the connecting terminal of the motor and a wire inlet end of an alternating current contactor (KM4); a wire inlet end of an alternating current contactor (KM2) is connected with the connecting terminal of the motor, the connecting terminal of the motor is switched in a wire inlet end of an alternating current contactor (KM3) through the wire inlet end of the alternating current contactor (KM2), a wire outlet end of the alternating current contactor (KM2) is connected with the connecting terminal of the motor, and the connecting terminal of the motor is switched in a wire outlet end of the alternating current contactor (KM3). According to the circuit design method adopted by the super-efficient double voltage motor factory test circuit, three kinds of voltage conditions can be simultaneously detected, test device wiring times are reduced, and work efficiency is improved.

Description

technical field [0001] The invention relates to a circuit, in particular to a factory test circuit for an ultra-high-efficiency double-voltage motor. Background technique [0002] Nima motor is an oil well motor used in the American market. The motor has 12 terminals and three different voltage connection methods. At present, one voltage and one connection method are generally used in the factory test of the motor. The three voltages are the same. It needs to be wired three times, which is neither safe nor convenient, and the efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a factory test circuit for an ultra-high-efficiency double-voltage motor, which can solve the problems of frequent wiring and low efficiency during the motor test. [0004] The problem to be solved by the present invention is achieved through the following technical scheme: a motor test circuit, including a factory test bench, a three-phase induct...
