Description
Technical field
The utility model relates to a kind of ancillary test equipment, relates in particular to a kind of high voltage precision instrument heating cabinet in winter, is applicable to winter job testing ground, belongs to electrical test technical field.
Background technology
At present, outdoor test operation in winter instrument used needs very high accuracy mostly, but in the winter time especially the north winter, reduction along with temperature, when outdoor work, test specimen is being carried out in the process of high voltage test, usually occurring the too low normal working temperature interval that exceeds institute's service test instrument of ambient temperature.And directly have influence on the accuracy of the measured result of test apparatus, and cause measure error, affect the judgement of staff to measurement result.
Utility model content
The utility model, for above-mentioned problems of the prior art, provides a kind of high voltage precision instrument heating cabinet in winter, has solved the inaccurate problem of result of the test that winter, test apparatus Yin Wendu impact caused.
The technical solution of the utility model is as follows:
Casing adopts enclosed housing, and the inwall of casing arranges heat-insulation layer, and a side of casing arranges switching door, the top of casing arranges wire inlet/outlet hole, and the bottom of casing arranges bracket, on the sidewall of casing, hangs heating tube, heating tube connects power supply, between heating tube and power supply, is provided with temperature controller.
Described casing is telescopic suit casing.
Socket is equipped with in described casing side.
Described switching door doorway and wire inlet/outlet hole are provided with fluid sealant.
The inner periphery of described wire inlet/outlet hole is symmetrical arranged two circular arc packing rings, and circular arc packing ring connects set screw, and the radian of circular arc packing ring and wire inlet/outlet hole inner periphery radian match.
Described switching door outer surface is provided with handle.
Described heating tube is disc.
Described bracket consists of supporting bracket and fixed stop, and fixed stop is arranged on four jiaos of supporting bracket.
The utlity model has following advantage:
This heater incubator has solved the microtest instrument inaccurate problem of measurement result in the winter time effectively.During cold weather, need only test apparatus is put in heater incubator, and the temperature switching on power in the time of just can making test apparatus work is in test apparatus is normally worked serviceability temperature interval.Guarantee carrying out smoothly of high voltage test work, the accuracy of result of the test, for staff provides data accurately to the correct judgement of result of the test.
Reduce the error rate of testing operation in winter, improve the accuracy of testing operation in winter, the normal operation of guarantee test instrument safety, in the useful life of prolongation test apparatus, reduces maintenance cost.

In figure, 1, temperature controller, 2, power supply, 3, heating tube, 4, bracket, 5, handle, 6, heat-insulation layer, 7, casing.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe the utility model in detail.
Embodiment
As shown in Figure 1-2, casing 7 adopts closed telescopic vanning body, can, according to the size of test apparatus, regulate the volume of casing; The inwall of casing arranges heat-preservation cotton as heat-insulation layer 6, and a side of casing arranges switching door, and switching door outer surface is provided with handle 5, facilitates folding; The top of casing arranges wire inlet/outlet hole, and switching door doorway and wire inlet/outlet hole are provided with fluid sealant, can reach the test apparatus effect of heat-preserving anti-freezing more; The bottom of casing arranges bracket 4, and bracket consists of supporting bracket and fixed stop, and fixed stop is arranged on four jiaos of supporting bracket; On the sidewall of casing, hang disc heating tube 3, good heat dissipation effect, heating tube connects power supply 2, is provided with temperature controller 1 between heating tube and power supply, and socket is equipped with in casing side.
The inner periphery of described wire inlet/outlet hole is symmetrical arranged two circular arc packing rings, and circular arc packing ring connects set screw, and the radian of circular arc packing ring and wire inlet/outlet hole inner periphery radian match.
During use incubator door open, precision instrument is placed on bracket 4, switch on power 2, in case, be heated to temperature required after, stop heating; When reducing, temperature by temperature controller 12 continuation that switch on power, heated up again.By repeatedly working, the temperature inside the box can be kept within the specific limits.Test connection connects test specimen by incubator top wire inlet/outlet hole, and to be tested complete, first powered-down 2, housekeeping field instrumentation equipment, and test job completes.
