firstly, a technician sets a temperature sensor (23) according to the upper temperature value limits of different elements, and the detection end of the temperature sensor (23) can monitor the temperature of a circuit breaker, a combination switch, a sectionalizer and other elements respectively;
secondly, when one temperature sensor (23) detects that the temperature of the front-end element is overhigh, the semiconductor electronic refrigerating sheet (24) and the heat dissipation fan (26) are started through the controller (20), and heat dissipation and cooling work is carried out on a single electric element in the area;
thirdly, the technical personnel adjust the extrusion springs on the two sides of the sliding block (7) according to the weight and the specification of the element cabinet (3), and move outside the threaded rod (6) through the limiting ring, so that the lengths of the first extrusion spring (27) and the second extrusion spring (28) can be adjusted respectively, and the longer the length is, the lower the elastic coefficient is, and the higher the elastic coefficient is otherwise;
step four, when the cabinet body is collided to cause the element cabinet to generate inertia movement, the sliding block (7) is extruded through the support arm (12), the first extrusion spring (27) is extruded in the moving process of the sliding block (7), and meanwhile, the second extrusion spring (28) is stretched to form buffer protection work;
and step five, when the flexible film pressure sensor (18) collides, the electrode on one side inside the flexible film pressure sensor is contacted with the electrode on the other side, the pressure value generated by extrusion is determined through the change of the capacitance value, the pressure value is output to the microprocessor (36), and the pressure value is converted and sent to the recorder through the microprocessor (36).
