Abstract

The invention discloses an insulation and heat conduction sheath for measuring the temperature of a platinum resistor. Aluminum oxide ceramics or heat conduction plastic is selected as the base materials of the insulation and heat conduction sheath; a temperature measurement plane matched with a temperature measurement plane of a power cable connector is arranged on the lower portion of the front end of the insulation and heat conduction sheath; double-side heat conduction tape is arranged between the temperature measurement plane and the power cable connector; the lower portion of the rear end of the insulation and heat conduction sheath is of a semicircular structure to form a riding-type structure matched with an external insulation sheath of a power cable; a through hole, for making way, relative to a protrusion of the power cable connector is formed in the middle of the insulation and heat conduction sheath; belting limiting grooves relative to positions of a groove between the power cable connector and the external insulation sheath of the power cable and a groove between the power cable connector and a toggle clip of the power cable connector are arranged on the upper surface of the insulation and heat conduction sheath; an installment hole of a line for measuring the temperature of the platinum resistor is formed in the rear end of the insulation and heat conduction sheath, and an axial distance larger than 3mm is exists between a blind end of the installment hole and a terminal surface of the insulation sheath of the cable of the power cable connector. The insulation and heat conduction sheath is used for a power system, is installed on a cable connector of an electric switch cabinet, and is used for measuring the temperature of the cable connector.

Description

technical field [0001] The invention relates to an optional part for a multi-channel wireless temperature measuring sensor, in particular to a platinum resistance temperature measuring insulating heat conducting sheath. Background technique [0002] With the rapid development of production and the continuous improvement of people's living standards, the demand for electricity is also increasing, and the safe operation of electricity is particularly important. As a very important electrical equipment in the power system, the temperature verification of the switchgear is an important parameter for the normal operation of the equipment. Under the influence of various factors, the contact resistance will increase. When the current passes, the temperature will rise, which will cause the equipment to age and reduce the service life of the equipment. Seriously, it will cause overheating and damage to the cable joint, and even burn. If it is not handled in time, it will be very seri...
