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. There is a square groove in the middle of the block 3, and the upper cover 4 is embedded in the square groove. The bottom plate of the slider 3 is connected with a pressure block 6 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 sheet is i...

The invention provides a heating monitoring device for a sealed conductor connector. The temperature rise of a conductor of electrical equipment is effectively conducted to a heat sensitive wax sheet in time through a base; with the help of the character that the heat sensitive wax sheet is easy to melt when the temperature rises, a route that a sliding block moves downwards is obtained by utilizing a space provided after the heat sensitive wax sheet melts into molten liquid wax; and an upper cover is exposed when the sliding block is pushed to move downwards via the release of stored energy of a compression spring, so that the purposes of displaying and warning can be realized. The heat sensitive wax sheet can be mounted and displaced without dismounting the whole structure of the device, so that the heat monitoring device is convenient to use and maintain, simple in structure and low in cost; and the heating of the connector can be effectively monitored and warned, and the heating monitoring device can be repeatedly used.
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] In order to improve the safety factor and ensure the stable and reliable operation of the high-voltage switchgear, capacitors, copper (aluminum) bars on both sides of the main transformer and cable terminals in the substation, various closed insulation protection measures are taken. 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 prese...
