Embodiment Construction
[0016] As shown in the figure, a heat monitoring device for a closed conductor joint includes a base 1 and a housing 2 which is mounted on the outside of the base. The lower part of the base 1 is fixedly connected to the monitoring equipment through screw connections. The block 3 is provided with a square groove in the middle, and the upper cover 4 is embedded in the square groove. The bottom plate of the slider 3 is connected with a briquetting block 14 with a smaller size. The guide groove through which the side plate passes, the slider 3 slides up and down along the side plate of the casing 2 through the guide groove, and the sliding action and guidance are accurate and reliable; Fixed, a compression spring 7 is set between the upper cover 4 and the bottom plate of the slider 3; the lower part of the shell 2 is fixedly connected to the base 1 by screws, the structure is stable, and will not be loosened due to equipment vibration and handling; the temperature-indicating wax s...

The closed conductor joint heating monitoring device of the present invention timely and effectively conducts the temperature rise of the conductor of the electric power equipment to the temperature-indicating wax sheet through the base. With the help of the characteristic that the temperature-indicating wax sheet is easy to melt after the temperature rises, the temperature-indicating wax sheet is melted into a melting wax liquid to provide The space change of the slider obtains the stroke of the slider moving downward, and releases the stored energy through the compressed spring to push the slider down to expose the upper cover to achieve the purpose of display and warning, and can be installed and replaced without dismantling the overall structure of the device The temperature-indicating wax sheet is easy to use and maintain, simple in structure, low in cost, can effectively monitor and warn the heat generation at the joint, and can be reused.
Description
technical field [0001] The invention relates to a heat monitoring device for a closed conductor joint, which is applied to power equipment in substations in the power industry. Background technique [0002] The high-voltage switchgear, capacitors, copper (aluminum) bars on both sides of the main transformer and cable terminals in the substation adopt various closed insulation protection measures to improve the safety factor and ensure the stable and reliable operation of the system. The contact resistance of electric equipment, long-term load and high current in the operation of power equipment is easy to generate heat at the conductor connection; and various protection measures will affect the temperature rise monitoring effect of the conductor connection, and cannot directly, effectively and accurately monitor and warn the conductor temperature rise. It is easy to cause safety hazards. Contents of the invention [0003] The technical problem to be solved by the present ...
