Abstract

The invention provides a heating structure capable of automatically increasing the insulation value of a motor, and relates to the field of motor detection and maintenance equipment. The heating structure comprises two switch power supplies, a temperature sensor, a display, a control circuit and a field effect transistor, which are arranged in the motor, wherein the two switch power supplies form a pulse width modulation circuit through connection of the field effect transistor and the control circuit, the pulse width modulation circuit is connected to the winding of the motor, the control circuit is further connected to the temperature sensor, the temperature sensor detects the instant temperature of the winding of the motor and transmits electric signals to the display, and the control circuit adjusts the input current according to the temperature detected by the temperature sensor. The motor insulation heater utilizes the principle of low voltage and heavy current to heat the winding of the motor, and the frequency conversion allows automatic adaptation of the inductance value of the motor. The insulation of the motor can be repaired without dismounting the motor. The motor is not dismounted, and only connecting a power line and turning on a power switch are needed. Heating temperature can be controlled automatically.

Description

technical field [0001] The invention relates to the field of motor detection and maintenance equipment, in particular to a heating structure that can automatically improve the insulation value of a motor. Background technique [0002] In the rainy season, due to the increase of moisture in the air, the insulation of the motor is easy to reduce, which will affect the electrical safety performance. The traditional method is to put the motor in an oven for a certain period of time or in a dry environment. This method is inconvenient to operate. The time is too long and other disadvantages. This heater is to increase the temperature of the winding by adding low-voltage and high-current direct current to the motor winding to drive away the moisture and increase the insulation. This heater has the characteristics of simple operation, safety, convenience and small size. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a heating...
