Abstract

The present invention relates to the technical field of soft starters and more particularly to a slip ring motor soft starter. The slip ring motor soft starter comprises a soft starter case body, a top end of the soft starter case body is provided with an upper pin, a bottom end of the soft starter case body is provided with a lower pin, a turnover door is set on one side of the soft starter casebody, the turnover door is rotatingly connected to the soft starter case body through a hinge, and an inner side of the soft starter case body is provided with a first partition plate. According to the slip ring motor soft starter, an infrared light bulb and a hot air blower are set, the set infrared light bulb and hot air blower can generate heat for drying moisture, when the soft starter is stopped, the moisture inside the soft starter is dried quickly through the heat radiation generated by the infrared light bulb and the hot air flow generated by the hot air blower, the heat generated by the infrared light bulb is concentrated and stable, the hot air flow generated by the hot air blower has strong fluidity, the drying efficiency is improved, and an electricity leakage or short circuitaccident caused by heavy moisture is avoided.

Description

technical field [0001] The invention belongs to the technical field of soft starters, and in particular relates to a slip ring motor soft starter. Background technique [0002] Slip ring motors are also called three-phase wound rotor AC asynchronous motors. This type of motor is usually used for driving in mechanical equipment that requires high rotational torque. The soft starter is a motor that integrates soft start and soft stop. , light-load energy-saving and a variety of protection functions in one novel motor control device, its main composition is a three-phase parallel thyristor connected in series between the power supply and the controlled motor and its electronic control circuit, through the soft starter can control The slip ring motor plays a protective role. [0003] However, the soft starters currently on the market are not effective. When used in a humid environment, due to the heavy humidity, it is easy to cause leakage or short circuit accidents, which affe...
