HZAOC RCJ-25B Insulator Thermal Shock Testing Machine

RCJ-25B

Insulator thermal shock testing machine

Applications

The insulator thermal shock testing machine is mainly used for the determination of the ability of the insulator to withstand a certain temperature shock in a short period of time, to provide a rapid temperature change environment for the porcelain insulator for high-Voltage lines, and to test the physical environment destructive test equipment for the damage of the insulator caused by sudden rain on the surface of the high temperature environment in summer.

Operating Principle

The high temperature area is automatically compared with the low temperature area, the specified temperature of the insulator thermal shock is automatically adjusted, the Tester is heated and maintained according to the temperature rate according to the specified temperature, and the bottom plate of the high temperature area is automatically opened after the specified time, and the sample is automatically sent to the cold water area with a special mechanical mechanism, and the valve plate in the cold water area is opened and the water vapor is actively discharged, and the sample is cooled. The test specimen is inserted and removed by means of an automatic pneumatic device.

Cabinet structure

1. The structure of the Test Chamber: the overall combination of structural form, divided into upper and lower structural formula and left and right structural formula, the box occupies a small area, compact structure and beautiful appearance, and the refrigeration unit is placed in an independent unit box, so as to reduce the impact of vibration and noise on the Test Chamber during the operation of the refrigeration unit, and at the same time facilitate the installation and maintenance of the unit, and the electrical control panel is placed on the right plate of the Test Chamber for easy operation

2. Outer wall material of the box: cold-rolled steel plate, electrostatic spraying treatment on the surface;

3. Inner wall material of the box: stainless steel plate (SUS304);

4. Thermal insulation materials: high-temperature fire-resistant rigid polyurethane foam or high-temperature fireproof microfiber glass insulation cotton;

5. Test chamber door: equipped with double silica gel sealing and sealing strip heating device, with self-limiting temperature heating belt, to prevent condensation and frost during the test;

Cooling system

The cooling system of this equipment ensures that the water can be kept at room temperature under the operation of high temperature air, and the temperature does not exceed 2K, and the water temperature does not exceed 50 °C under any circumstances.

Heating system

1. The heater adopts porcelain frame nickel-chromium wire electric heater, which has low thermal inertia and long life. The controllable pulse duty cycle PID signal is output by the instrument, which is controlled by a solid-state relay, and the control is stable and reliable.

Control system

1. AOC control device: the man-machine interface adopts color large-screen LCD touch display, and the control interface adopts full Chinese display, which can set test parameters, curves, total running time, total running time, heater working status and time, etc. The compilation of the control program adopts the human-machine dialogue mode, the interface is friendly, and the automatic operation function of the refrigerator can be realized only by setting the temperature.
