Abstract

The invention provides an insulation performance testing device, a thermal insulation performance testing method and an application thereof, which relates to the technical field of insulation performance testing. The thermal insulation performance testing device comprises a heating temperature control device, a heater, a heat transfer plate, a cover plate, a first thermocouple, a second thermocouple, and a temperature recorder. The heating temperature control device and the heater are mainly used for controlling the temperature of the hot surface of the heat insulating sample during the insulation testing. The heat transfer plate is provided with through holes, the heat provided by the heater can passes through the heat transfer plate to form an uneven heat distribution, thereby simulatinga non-uniform temperature field. The insulation performance testing device has a simple structure and convenient operation and is able to simulate the non-uniform temperature field under different conditions according to the actual test requirements, which can meet the test requirements of various non-uniform temperature fields. The insulation performance testing device, insulation performance testing method and application also provides a method for testing thermal insulation performance, the insulation performance test can be realized by the insulation performance test device. The method issimple, reliable, and has high maturity, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of heat insulation performance testing, in particular to a heat insulation performance testing device, a heat insulation performance testing method and an application thereof. Background technique [0002] Nowadays, thermal conductivity is usually used to evaluate the thermal insulation performance of thermal insulation materials. Thermal conductivity is usually used to characterize the thermal insulation performance of a single, homogeneous material. For multi-layer composite thermal insulation materials or insulation composed of multi-layer composite thermal insulation materials For hot products, the thermal conductivity cannot directly represent the effect of heat insulation. [0003] And with the continuous development and progress of various types of equipment, the thermal environment of various types of equipment in the equipment is becoming more and more severe, and the power system, transmission syst...
