Description
Technical Field
[0001] The utility model relates to a spring tension detection device for switch detection, belonging to the technical field of switch detection spring tension detection. Background Art
[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. The main function of the switch cabinet is to open and close, control and protect the electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet mainly include circuit breakers, disconnectors, load switches, operating mechanisms, mutual inductors and various protection devices. According to the voltage level classification, AC1000V and below are usually called low-voltage switch cabinets, AC1000V and above are called high-voltage switch cabinets, and sometimes the voltage of AC10kV in the high-voltage cabinet is called medium-voltage cabinet. The main failure form of the switch cabinet is discharge burning, among which contact heating and burning is the main failure form. Contact heating is mainly caused by large contact resistance. Contact resistance is affected by factors such as contact finger pressure, contact area and contact material type, among which contact finger pressure is the main determining factor. The contact finger pressure is applied by the compression spring. When the power transmission load is low, the current is small and the temperature is low. When the load is peak in summer or winter, the current increases and the temperature rises. When the temperature rises or the compression spring ages, the tension will decrease, resulting in a decrease in contact finger pressure, further increase in contact resistance, further increase in temperature, worsening of the cycle, and ultimately burning of the contacts.
[0003] In the prior art, when performing tension testing on a compression spring, a tension testing instrument is required to measure and test its tension and elastic force to prevent the tension of the compression spring from affecting the functions of the switch cabinet and the switch button during actual use. However, the spring tension testing instruments on the market are difficult to perform tests of different pressures and tensions according to the different shapes of springs used inside the switch during the measurement process, and are difficult to adjust and install. Therefore, a spring tension testing device for switch testing that can be adjusted according to the switch type and spring type is designed. Utility Model Content
