Description

technical field [0001] The invention relates to the technical field of electric heating element deformation inspection, in particular to a detection and control system for electric heating element deformation. Background technique [0002] The electric heating element deformation inspection equipment is an important special tool for the replacement and maintenance of the electric heating element of the voltage stabilizer. It is used to check the surface damage of the electric heating element inside the voltage stabilizer. The electric heating element is installed at the lower part of the voltage stabilizer, which is prone to swelling and rupture after long-term use. Therefore, it is necessary to check the deformation of the electric heating element. Since the inside of the voltage stabilizer has certain radioactivity (not less than 50mSv / h), the current electric heating Component deformation inspection cannot reliably detect the deformation of the electric heating element un...

The electric heating element is installed at the lower part of the voltage stabilizer, which is prone to swelling and rupture after long-term use. Therefore, it is necessary to check the deformation of the electric heating element. Since the inside of the voltage stabilizer has certain radioactivity (not less than 50mSv / h), the current electric heating Component deformation inspection cannot reliably detect the deformation of the electric heating element under the condition of isolating radioactive contamination and ensuring the safety of the testing personnel, which has resulted in the urgent need for reliable testing of the electric heating element and the contradictory status quo to ensure the safety of the testing personnel
