Test device (such as Fig. 1) includes one layer of mica-glass board, support leg, low-field electrode and multiple high-field electrodes, in four support legs
End connection mica-glass board, lower end connect low-field electrode, and high-field electrode passes through mica-glass board；Wherein high-field electrode is removable
It is revocable, it is limited using single layer mica-glass board, it is difficult to ensure that high-field electrode is in nature plumbness, i.e. high pressure
Electrode lower end surface cannot be guaranteed to completely attach to sample face, high-field electrode may tilt, and forms point with detection sample or line connects
Touching, this will have a direct impact on the accuracy of testing result.
The existing Chinese patent patent No.: 2015206414104, patent name: Inverter fed motor tester sample fixed case is used
In the detection of enameled wire corona-resistance property, and it is still incompatible for the detection of solid insulating material；Enameled wire and solid insulation material
Expect separate detection, cost will increase using different instruments.
Utility model content

As a result accuracy, reduce a kind of solid insulating material Inverter fed motor test device and Inverter fed motor tester of testing cost.
The technical solution adopted in the utility model is such that
A kind of solid insulating material Inverter fed motor test device, including mica-glass board, support leg, low-field electrode and multiple high
Piezoelectricity pole, four support leg upper ends connect mica-glass board, and lower end connects low-field electrode, and high-field electrode passes through mica-glass board；
The mica-glass board has two layers, is arranged in parallel up and down.
Inverter fed motor tester comprising above-mentioned solid insulating material Inverter fed motor test device.
Further, it is provided in tester sample fixed case dismountable for placing solid insulating material Inverter fed motor
The insulating substrate of test device.
Further, supporting block is set in the sample fixed case side wall.
In conclusion due to the adoption of the above technical scheme, the beneficial effects of the utility model are:
One layer of mica-glass board of the utility model relative increase limits high-field electrode by the double-deck mica-glass board, protects
It is naturally vertical to demonstrate,prove high-field electrode, so that its contact with specimen surface forming face with face, is further ensured that the accurate of testing result
Property；To conventional Inverter fed motor tester simple modifications, increase above-mentioned Inverter fed motor test device, it is made to have both test enameled wire and solid
The function of insulating materials reduces the cost for separately adding instrument.

Pole 4 passes through mica-glass board 1；The mica-glass board 1 has two layers, is arranged in parallel up and down；Pass through set between two layers of mica-glass board 1
The limited post connect in support leg 2 separates.
Inverter fed motor tester comprising above-mentioned solid insulating material Inverter fed motor test device.
It is provided in tester sample fixed case 5 dismountable for placing solid insulating material Inverter fed motor test device
Insulating substrate 6；Supporting block 7 is set in 5 side wall of sample fixed case, insulating substrate 6 can be placed in supporting block 7.
Solid insulating material Inverter fed motor test device low-field electrode 3 and high-field electrode 4 by conducting wire with it is original in tester
Binding post connection.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
