Description
Technical field
The utility model relates to a kind of chromatograph box based on modular heating technology, belongs to oil dissolved gas on-line monitoring field.
Background technology
Transformer is as the most important power-supply unit of electric system, and be also one of equipment of costliness the most, the degree of its reliability service is directly connected to the safe operation of whole electric system.Most of internal faults of power transformer can judge according to the analysis of the dissolved gas in transformer oil, and therefore the detection technique of Gases Dissolved in Transformer Oil just seems particularly important.Judge whether operating oil-filled power equipment exists the faults such as overheated, the electric discharge of latency by oil dissolved gas on-line monitoring system, be the effective means ensureing that power grid security effectively runs, Ye Shi oil-filled electric equipment manufacturing firm carries out the necessary means of factory inspection to its equipment.Chromatographic column heating arrangement is the pith of oil dissolved gas on-line monitoring system, and current heating arrangement mainly contains directly to chromatographic column heating, and derby heats chromatographic column.Air heats chromatographic column, and derby is to indirectly to chromatographic column heating etc. heating means.But different heating means are also different on the impact of column performance, mainly also there is problem described below in it:
1. the design that has of heating part is too numerous and diverse, installs inconvenient and troublesome maintenance;
2. heating means cannot be heated to 50 DEG C from room temperature rapidly and uniformly;
3. heating means all cannot meet the requirement of column performance maximization to temperature control precision.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple for structure, is convenient to the heating chromatograph box of installation and maintenance; Further, the technical problems to be solved in the utility model is to provide a kind of chromatograph box of energy rapid and uniform heating; Further, the technical problems to be solved in the utility model is to provide the chromatograph box that a kind of temperature control precision reaches the temperature difference ± 0.1 DEG C.
For solving the problem, the technical solution of the utility model is: a kind of chromatograph box based on modular heating technology, heat-conducting metal casing and case lid form a closed square box, in the metal level of described heat-conducting metal casing, heating rod and temperature sensor are installed, described case lid is provided with blower fan, and chromatographic column is fixed on described heat-conducting metal box house.
Principle of work of the present utility model is heating rod is METAL HEATING PROCESS, is that post case inner air heats by metal, and blower fan rotates and makes box house air carry out thermal cycle, thus reaches heating rod and indirectly heat chromatographic column.Whole post box-shaped becomes modular entirety, and inner structure is succinct, when installing and keep in repair, whole post case is loaded onto or is taken off.
Further, the material of described heat-conducting metal casing and case lid is metallic aluminium, metallic aluminium there is good thermal conductivity, casing can be heated up quickly and evenly.
Described heating rod to be quantity be 4 integral multiple, be distributed in four limits of described heat-conducting metal casing equably.Thus can evenly heat heat-conducting metal casing rapidly.
Described heating rod quantity is 4, is distributed in the corner of described heat-conducting metal casing.
Described chromatographic column is connected with case lid by tinsel, is hung on the below of described blower fan vacantly, to make the contact area of chromatographic column and hot-air maximize, chromatographic column synchronously can be heated up with casing.
Further, described temperature sensor is PT100 temperature sensor, and is connected with PID temperature controller, adopts this structure, can improve temperature control precision, and the temperature difference controls at ± 0.1 DEG C.
Basic structure of the present utility model achieves the modularization of heating chromatograph box, and later maintenance dismounting easy for installation is also very convenient; As to improvement of the present utility model, casing adopts the material of metallic aluminium, four heating rods is uniformly distributed in casing corner, is hung in casing by unsettled for chromatographic column, all can improve heating process fast and homogeneity; Further improve as to of the present utility model, adopt T100 temperature sensor, and PID temperature controller, heating-up temperature precision controlling can be made in the temperature difference ± 0.1 DEG C.Therefore the utility model, dismounting is easy to maintenance, intensification Quick uniform, stable temperature control, and chromatographic column can be made in constant temperature hot environment to reach best performance.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figures 1 to 4, a kind of chromatograph box based on modular heating technology, heat-conducting metal casing 1 and case lid 6 form a closed square box, heating rod 4 and temperature sensor 5 are installed in the metal level of described heat-conducting metal casing 1, described case lid is provided with blower fan 2, it is inner that chromatographic column 3 is fixed on described heat-conducting metal casing 1.
Principle of work of the present utility model is heating rod 4 is METAL HEATING PROCESS, is that post case inner air heats by metal, and blower fan 2 rotates and makes box house air carry out thermal cycle, thus reaches heating rod indirectly to the effect that chromatographic column 3 heats.Whole post box-shaped becomes modular entirety, and inner structure is succinct, when installing and keep in repair, whole post case is loaded onto or is taken off.
Further, the material of described heat-conducting metal casing 1 and case lid 6 is metallic aluminium, metallic aluminium there is good thermal conductivity, casing can be heated up quickly and evenly.
Described heating rod 4 is the integral multiple of 4 for quantity, is distributed in four limits of described heat-conducting metal casing 1 equably.Thus can evenly heat heat-conducting metal casing 1 rapidly.
