Portable device for constant-temperature heating and heat preservation of instrument

Abstract

The invention relates to the technical field of electric power detection equipment, in particular to a portable device for constant-temperature heating and heat preservation of an instrument, which comprises a power supply module, an automatic temperature control heating module, a high-precision PID temperature control module, an alarm module, a temperature collection module, a heat preservation module, an over-temperature protection module, an air duct design and a portable draw-bar box. According to the automatic temperature control heating module, a PTC resistive heating component is adopted in the heating module, no open fire exists, the automatic temperature control characteristic is achieved, the heat output end of the circulation channel passes through the air channel, then directly enters the heat-preserved detection equipment and then enters the constant-temperature heat insulation chamber after being output through the air outlet of the detection equipment, so that the internal environment temperature of the case of the detection equipment can quickly meet the set temperature requirement, and the internal temperature of the instrument and the constant-temperature heat insulation chamber can be quickly balanced.

Description

technical field [0001] The invention relates to the technical field of electric power detection equipment, in particular to a portable device for constant temperature heating and heat preservation of the instrument. Background technique [0002] In recent years, my country's economy has developed rapidly, and the demand for electricity in various fields has risen sharply. Substations have gradually become an important trend in the development of my country's power grid. Substations have an important impact on the safe and stable operation of power systems. During the long-term operation of substations, power equipment It is easy to be affected by various factors and cause operation failures. In order to reduce operation failures, it is necessary to regularly or irregularly detect the operation of substation power equipment; [0003] Most of the existing testing work needs to be carried out outdoors. The ambient temperature of general equipment testing instruments is required ...
