Special thermostat for online transformer oil detection chromatography columns

Abstract

The invention discloses a special thermostat for online transformer oil detection chromatography columns. The thermostat comprises a box, wherein the box is divided into an inner box body and an outer box body; a central processing unit, oil chromatography columns and a heating device are mounted in the inner box body; a terminal is arranged at the back of the outer box body, and a cooler is arranged on the top of the outer box body and connected with the inner box body; the oil chromatography columns are arranged on oil chromatography column bases, the oil chromatography column bases are connected with a supporting ring, and oil chromatography column supporting bases are arranged on the oil chromatography column bases and connected with the heating device; the heating device comprises a finned radiator, heating pieces, a heating device bottom table and high-temperature-resistant fans; the heating pieces are attached to the finned radiator, the high-temperature-resistant fans are arranged under the heating device bottom table, and each of the high-temperature-resistant fans, the finned radiator and the oil chromatography columns is equipped with a thermometer. The thermostat is reasonable in design, and the temperature is easy to control and no open flames are generated during use, so that the special thermostat is safer and more reliable to use, simpler in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of equipment for detecting oil chromatographic columns of power transformers, in particular to a special thermostat box for on-line detection of transformer oil chromatographic columns. Background technique [0002] At present, the effective detection and analysis of transformer oil in the power supply system generally adopts transformer detection oil chromatograph, and the oil chromatographic column in the constant temperature box is heated by conduction heating or heating wire. First, the conduction heating method of the oil chromatographic column is first to put the oil chromatographic column into the metal block, and then use the heating plate to heat the metal block, so that the heat of the metal block is transferred to the oil chromatographic column, and then the purpose of heating the oil chromatographic column is achieved. Although the heating method is simple and there is no open flame, it is diffic...

Problems solved by technology

First, the conduction heating method of the oil chromatographic column is first to put the oil chromatographic column into the metal block, and then use the heating plate to heat the metal block, so that the heat of the metal block is transferred to the oil chromatographic column, and then the purpose of heating the oil chromatographic column is achieved. Although the heating method is simple and there is no open flame, it is difficult to control the heating temperature, and the temperature is difficult to meet the requirements of product performance. The resistance heating wire with an open flame, the heated air reheats the oil chromatographic column, the hot air circulates in the incubator, and the motor is placed outside the incubator. In this way, the heating wire is placed in the air to dissipate heat, so the temperature is very high. High and easy to generate open flames, there is a danger of deflagration when used online, and the safety factor of use is low
