A, AB932-10 type winding on impact resistance voltage tester overview
Impulse voltage tester of AB932-10 type of winding resistance, is suitable for rated voltage 380V Detection of micro motor, DC motor winding under insulation on the ground, can also be used for transformer windings, windings of electrical insulation detection. A part of electric motor, electric tools, etc. are the main transformer coil winding, because the coil insulation material is not the same, especially the difference operator process level, making all kinds of coil products in production and handling will cause insulation damage in different degree, which exists between the windings of the shell insulation faults of various forms before, these weak links and breakdown or damage in not meet certain conditions, the coil or winding no significant change on shell distributed capacitance, using conventional methods often can not be identified, the buried faults for such coil. Therefore, the insulation performance is a key index for outdoor use of motor, transformer etc.. According to our country GB3111.1 , JB/T16927.1 , JB/T10098-2000 The relevant standards, the manufacturing equipment to produce standard lightning impulse insulation, impact test on the ground.
Two, AB932-10 type winding to withstand voltage tester main technical parameters:
The 1. shock wave voltage: 0~10KV The range can be adjusted continuously. 5%
2. front time: 1.2us . 30%
The 3. half peak time: 50uS . 20%
4.: shock interval 1s
5. times of shock: Three second
6.: one-way impact direction
Three, AB932-10 type winding to withstand voltage tester, the rear panel and control keys
The low pressure indicator, the indicator lights the test indicator lamp preheating
The oscilloscope interface will power switch, start button, reset button
Only the voltage adjusting knob
Four, AB932-10 type winding resistance operation method of impulse voltage tester
One AB932 A series of test instrument produces high voltage at work, especially when using Caution!, the frame must be reliable grounding (rear panel with a grounding terminal) please read the manual carefully before use. The operating personnel must be trained.
2. access 220V The voltage of power line, oscillograph is inserted into the host power socket plate oscilloscope. The oscilloscope interface with the oscilloscope CH1 (or CH2 ) through the interface connected to the good.
3. boot, power indicator light, voltage adjusting knob counterclockwise to Zero Connect the sample to the rear. HV , Zero Two terminal connection method (reference six. Wiring method)
4. adjusting parameters and oscilloscope menu (specific operation instructions refer to the oscilloscope)
5. to preheat indicator light. Connect the load, click on the start button. At this time, the high voltage circuit is switched on. The voltage adjusting knob, voltage to the desired voltage value (the first time). At this time, high pressure on the impact load continuous three times interval 1s So, to determine whether the breakdown observed through the oscilloscope waveform, determine the load is qualified.
6. through the oscilloscope related operation knob, determine the correct waveform of load.
Five, how to determine the load waveform by qualified and unqualified
Note: after the access load waveform, but the wave tail T The axis can be judged as qualified products.
Six, connection method
3. load must be put on the insulation medium.
2 load regardless of internal winding connection.

The other eight.
1. the instrument should be to keep the temperature in the room Zero C ~ Forty C, the relative humidity is less than 80%, and in the air does not contain harmful substances to cause corrosion.
2. warranty period: from the delivery date, for a period of one year.
In 3. the company product life-long maintenance.
4. the warranty period, due to improper operation of the user caused by damage to the instrument, maintenance fee.
5. manufacturing plants have the right to change without notice of the instrument.
Nine. DS5022ME Digital oscilloscope operating instructions
Connect the power (1. AC220V Press the power switch, etc.) 6S After the emergence of the surface at the top right hand corner AUTO Key to the display in the upper left corner AUTO
2. click on the right TRIGGER Box MENU The right button, the menu will appear, as shown below. If the menu is not correct please click the corresponding button, reset menu to the right now
If you use 3. CH1 According to the passage, please OFF Clear menu button, and graphics in each scan line, then click the CH1 button, then the following menu, if the menu is not correct please click the corresponding button, reset menu to the right now
More than 4. menus are correct, down to determine the parameters in the chart below CH1 All 500mVTime20.000us, adopt SCALE/ Turn knob, regulation CH1 All 5V - 2.00mv, adopt SCALE Turn knob adjustment Time50.00S- 20.00nS The following parameters shall prevail
5. then you can press the instrument operation method of interturn began operation, the surface oscillation wave oscilloscope, then the oscillation wave size (amplitude), length (Pin Kuan) by up and down SCALE About. SCALE Turn the knob to change
6. if you want to make the waveform and moving through, please POSITION Turn the knob to change
7. if the waveform is not stable, please LEVEL Turn the knob to change
8. note that the other button can not move as much as possible not to move
9. if the storage method, in determining a good waveform on the oscilloscope, press" REF "Key, then press" save "corresponding keys on the waveform storage oscilloscope.
