Problems solved by technology

However, its normal working temperature requires -10°C-40°C to work normally, and the lowest temperature in winter in Northeast China is around -35°C, which leads to the failure of electronic components to work normally during work, often black screen and failure to start
There are many types of instrument boxes and tool boxes in the current market, and the effects of various products are quite different, and there is no special incubator for this type of equipment, which brings great troubles to on-site operations

Abstract

The invention discloses an insulation box for a transformer DC resistance tester. The insulation box comprises a box body formed by hinging a box base and a box cover; a heating plate, an intelligenttemperature controller and an electric leakage protection power supply plug, wherein the intelligent temperature controller and the electric leakage protection power supply plug are arranged at adaptive positions in the box cover. The transformer DC resistance tester is arranged in the box base, and at least one heating plate is arranged at the adaptation position of the side wall adjacent to thetransformer DC resistance tester. The electric leakage protection power supply plug, the intelligent temperature controller and the heating plate are connected in series through a wire. According to the requirement for the running environment temperature of the instrument, the temperature adjusting is carried out, the heat preservation in the box can be carried out, the temperature adjusting speedis high, the size is small, and the carrying is convenient, and time and labor are saved. The trouble brought to the work due to the environment is thoroughly solved. A lot of purchasing instrument funds are effectively reduced for enterprises, and good economic and social benefits are achieved.

Description

technical field [0001] The invention relates to an incubator, in particular to a transformer DC resistance tester incubator suitable for use in power systems, petroleum, chemical industry, metallurgy and other industries. Background technique [0002] At present, the transformer DC resistance tester is a new type of instrument designed with modern electronic technology. The instrument integrates a high-stability constant-current power supply and a test part, and the entire test process is completed by a single-chip microcomputer. The instrument has the characteristics of easy operation, wide measurement range, stable and accurate test data, perfect back EMF protection function and strong anti-interference ability. It is suitable for DC resistance testing of distribution transformers and large power transformers, and is widely used by power companies. However, its normal working temperature requires -10°C-40°C to work normally, and the lowest temperature in winter in Northeas...
