One of mark.The main harm of mineral insulation W/O is to make paper insulation by permanent destruction.Minor amount of water present in insulating oil
Divide has great harm to the electric property and physicochemical property of dielectric, and moisture can cause the breakdown potential pressure drop of insulating oil
It is low, dielectric dissipation factor increase, meanwhile, the dominant catalyst of moisture or insulating oil oxidation, promote insulation oil degradation, by
Tide, infringement equipment, cause the operational reliability and service life reduction of power equipment, or even jeopardize personal safety.Advised in GB/T 7595
Determining the electrical equipment W/O that voltage class is 1000kV is divided to content two stages in fresh oil and operation to must not exceed respectively
8mg/L and 10mg/L, it can thus be appreciated that the height of the quality requirement of the micro- water of 1000kV substation transformer insulating oils.Current detection side
Method is that sampling is then returned to laboratory and detected at the scene.In the process, the oil samples that insulate are easily by natural environment
The influence of moisture, especially in the higher environment of humidity, cause take out sample can not truly reflect sometimes it is micro- in insulating oil
The truth of water content.
The content of the invention
The purpose of the present invention is to propose a kind of micro- water test of 1000kV transformer insulation oils in view of the shortcomings of the prior art

Touching display screen is installed on the left of upper surface, injection port is formed with the middle part of case lid, dehumidifying is installed on the right side of injection port
Switch, dehumidification module switch is installed in instrument box side wall, set at instrument box bottom in the promising instrument box of installation
The power line of available electricity, is fixed with central processing unit, central processing unit is connected with dehumidification module, and control removes inside instrument box
The working condition of wet module, central processing unit are connected with test module, and control test module is surveyed to detected insulation oil sample
Examination, central processing unit are connected with touching display screen, the course of work of central processing unit are realized by touching display screen, simultaneously
Display is detected the testing result of insulation oil sample.
Moreover, the injection port is with externally threaded injection port, lid is further installed with injection port.
Moreover, the dehumidification module further comprises thering is fan, heat exchanger and lithium battery；The test module is into one
Step includes micro- water tester of coulomb meter electrolytic cell, agitator, electrolytic circuit and measuring circuit.
The advantages and positive effects of the present invention are：
1st, portable micro-water test device provided by the invention reduces the influence that environment is tested insulating oil, it is possible to increase
The authenticity of micro- water test in insulating oil, improves the accuracy of test result, and the fluid exceeded to transformer is taken reliably in time
Measure, it is finally reached and samples qualified, saving sample time, reduction testing cost, the purpose of high efficient and reliable analysis insulating oil.
2nd, apparatus of the present invention have simple in construction, easy to operate, it is fast and effective, improve efficiency the advantages that.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the specific module connection structure schematic diagram in test box of the present invention.
Embodiment
Present example is further described below：It is emphasized that embodiment of the present invention is illustrative
, rather than it is limited, therefore the present invention is not limited to the embodiment described in embodiment, it is every by this area skill
The other embodiment that art personnel's technique according to the invention scheme is drawn, also belongs to the scope of protection of the invention.
Micro- water test device of a kind of 1000kV transformer insulation oils, as shown in figure 1, the instrument box including upper opening
8, twisted at the upper shed of instrument box by hinge 2 and case lid 7 is housed, the cramp 5 and instrument box that case lid passes through front portion installation
Locking, innovative point of the invention is that touching display screen 1 is provided with the left of the upper surface of case lid, is formed with the middle part of case lid
Injection port 4, dehumidifying switch 6 is installed on the right side of injection port, micro- water tester switch is installed on instrument box right side wall
9, the power line 10 of promising instrument box internal unit power supply is installed at instrument box right side wall bottom, inside instrument box
