Description
Technical field
The utility model relates to a kind of survey instrument of insulation resistance, specifically a kind of measurement mechanism of measuring rotor insulation in rotation.
Background technology
The part of detecting that insulation megohmmeter of the prior art is equipped with mostly is test pen or test clamp, test pen or test clamp test during general Electric Power Equipment Insulation resistance more for convenience, but when test pen or test clamp are measured to the measurement mechanism of rotor insulation in rotation, because of test pen or the test clamp can't remain valid and contact with measured position, so there is following defect in it: 1. because of test pen or test clamp, be subject to the effect of tangential force while contacting with measured position, during measurement, test pen or test clamp very easily throw away with rotation, this meeting crisis survey crew safety, 2. test pen or test clamp contact unreliablely with measured position, and measured value is forbidden, and during test, leakage current is large, 3. test pen or test clamp and measured position are because of galling, and test pen or test clamp very easily damage.
Summary of the invention
The purpose of this utility model is to provide a kind of measurement mechanism of measuring rotor insulation in rotation, and it is simple in structure, easy to use, has higher security performance, and can measure accurately the rotor insulation when rotated of motor.
To achieve these goals, the technical solution of the utility model is: the measurement mechanism of measuring rotor insulation in rotation, it is characterized in that: comprise brush and brush carrier, described brush is positioned at the middle part of brush carrier, one side of brush has the p-wire of insulating tape to be connected with wrapping, and the opposite side of brush is given prominence to a brush carrier part, in the brush carrier upper end, has stage clip to be pressed on brush, the brush carrier lower end is provided with insulation strip, and described insulation strip is by screw or be bolted on brush carrier.
In technique scheme, when needs are measured the insulation of rotor in rotation, the staff measures by brush.
From technique scheme, the required parts of the utility model are less, easy to assembly, therefore it is simple in structure; Because the utility model is provided with insulation strip, and the staff only need be connected to p-wire on the rotor or bearing of motor in use, therefore it uses simply; Finally, because the utility model is directly to measure rotor or the bearing insulation when rotated of motor by brush, because of brush and measuring point without metal friction, can make brush and measuring point keep reliably contacting, staff's personal safety while having guaranteed test, and make the result that tests out more reliable, the utlity model has higher security performance, and can measure accurately rotor or the bearing insulation resistance when rotated of motor.
The length of described insulation strip is 180-220mm, and described brush is 8-15mm from the outstanding length at the outstanding position of brush carrier.
The length of described insulation strip is 200mm, and the outstanding length at the position that described brush is outstanding from brush carrier is 10mm.
In technique scheme, the length of insulation strip is advisable with 180-220mm, and length be take 200mm as best.The outstanding length at the position that brush is outstanding from brush carrier is that 8-15mm is advisable, and outstanding length be take 10mm as best.
To sum up, the utility model is simple in structure, easy to use, has higher security performance, and can measure accurately rotor or the bearing insulation when rotated of motor.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-brush in figure, 2-brush carrier, 3-p-wire, 4-stage clip, 5-insulation strip, 6-screw or bolt, the part that the 7-brush is outstanding from brush carrier, the screw on the 8-insulation strip or bolt.
Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.Simultaneously, by explanation, make advantage of the present utility model, make the utility model become more clear and easily understand.
Consult accompanying drawing known: the measurement mechanism of measuring rotor insulation in rotation, it is characterized in that: comprise brush 1 and brush carrier 2, described brush 1 is positioned at the middle part of brush carrier 2, one side 1 of brush has the p-wire 3 of insulating tape to be connected with wrapping, the opposite side of brush 1 is given prominence to brush carrier 2 parts, in brush carrier 2 upper ends, have stage clip 4 to be pressed on brush 1, brush carrier 2 lower ends are provided with insulation strip 5, and described insulation strip 5 is fixed on brush carrier 2 by screw or bolt 6.
When needs are measured insulation resistance when rotated of the rotor of motor or bearing, the staff measures the rotor insulation when rotated of motor by brush.Stage clip 4 can reduce the vibration amplitude of brush 1.
The required parts of the utility model are less, easy to assembly, therefore it is simple in structure; Because the utility model is provided with insulation strip 5, and the staff only need be connected to p-wire 3 on the rotor or bearing of motor in use, therefore it uses simply; Finally, because the utility model is directly to measure the rotor of motor or bearing insulation resistance when rotated by brush 1, because of brush 1 with measured position without metal friction, can make brush 1 and measured position keep reliably contacting, staff's personal safety while having guaranteed test, and make the result that tests out more reliable, the utlity model has higher security performance, and can measure accurately rotor or the bearing insulation resistance when rotated of motor.
The length of described insulation strip 5 is 180-220mm, and the outstanding length at the position 7 that described brush 1 is outstanding from brush carrier 2 is 8-15mm.
The length of described insulation strip 5 is 200mm, and the outstanding length at the position 7 that described brush 1 is outstanding from brush carrier 2 is 10mm.
The length of insulation strip 5 is advisable with 180-220mm, and length be take 200mm as best.The outstanding length at the position 7 that brush 1 is outstanding from brush carrier is that 8-15mm is advisable, and outstanding length be take 10mm as best.
Insulating tape on described p-wire 3 can meet the 10kV class of insulation.When the insulating tape on p-wire 3 can meet the 10kv class of insulation, the utility model will have higher security performance.
