2. The water injection device includes a water pump, a solenoid valve, and a lifting motor. To use, first ground the shell of the test bench and connect it to the AC220V power supply. The test bench has a water inlet and a water outlet. The water inlet is used to add water to the water tank, and the water outlet is used to drain the water tank.

3. Connect the water pipe to the water inlet, open the water valve to fill the water tank, and close the water valve after filling it with water. Note: Do not leave when filling the water tank to prevent the water from overflowing.

4. Electrical Rubber Safety Gloves Testing System adopts circulating water to turn on the power of the test bench. At this time, the power indicator lights up and the system is on standby. There are 2 buttons on the front operation panel of the test bench, the glove test button and the emergency stop button. When a test product is installed in the sink test rack, press the glove to test, the water injection device is lowered, and the water injection port is inserted into the test product, and the test product is filled with water (only the test product is installed will inject water) until all the injections are made After the water reaches the water level required by the test, the water injection device automatically lifts and returns to the initial position, and the water injection is completed.

1. Use a wire to reliably connect the ground terminal of the control box, the test transformer, and the test machine with the ground wire of the test room.

2. The high-voltage output terminal of the high-voltage test transformer is connected to the red high-voltage input terminal on the side of the testing machine.

3. Turn on the power switch of the testing machine, the light in the switch lights up, and the indicator light next to the wireless transmission starts to flash intermittently after 1 second. The current of 8 channels on the testing machine displays "00.00". Because the current has not been applied, the display should All are "00.00", and the current display unit on the testing machine is mA. .

4. Installation of insulating boots: pour a certain amount of tap water (to make it conductive) into the stainless steel rectangular pool of the testing machine (the standard is water flooding the shoe surface), and pour a proper amount of steel balls into the insulating boots (cover the sole of the shoe, the height of which is not less than 15mm) ), soak the insulating shoe in water, put the stainless steel electrode chain into the shoe and touch the steel ball.

5. Installation of insulating gloves: Put a stainless steel square bucket in a rectangular pool, and fill the bucket with about half a bucket of water with a resistivity not greater than 100Ω·m (usually tap water is sufficient), and pour the same water into the tested gloves. Then immerse the glove in a stainless steel bucket so that the inner and outer surfaces of the glove are at the same height. The glove should have a 90mm exposed part of the water. This part should be wiped dry. Put the stainless steel electrode chain in the glove and immerse it in the water in the glove.

1. Commonly used insulating boots test

The voltage for the preventive test of insulating boots is 15kV, keep for 1 minute, and the leakage current is not more than 7.5mA as qualified. After putting the insulating boots, please directly press the operation interface to test.

2. Other tests

Other tests are equivalent to the traditional power frequency withstａnd voltage tester, the operation method is the same as the above, the test voltage can be defined according to the user's needs.

1. Low-voltage insulating gloves test:

The voltage for the preventive test of low-voltage insulating gloves is 2.5kV, which is kept for 1 minute, and the leakage current is not more than 2.5mA as qualified. After installing the test piece, directly press the operation interface on the testing machine to test.

2. High-voltage insulating gloves test

The method of the test is the same as 17.1, except for the two parameters of voltage and leakage current: the voltage for the preventive test of high-voltage insulated gloves is 8kV, hold for 1 minute, and the leakage current is not greater than 9mA as qualified.

1. Do not conduct tests on the trip unit and the test box during charging, as this will lead the power supply into the trip unit or the test box, causing the equipment to break down to the ground.

2. The high voltage output of this equipment is automatic step-up and automatic step-down. Please turn off the power switch and unplug the plug after the step-down is completed.

3. The transformer and testing machine of this instrument are both high-voltage equipment. Please arrange a safety enclosure and set up guards before you can conduct the test. The operation box (station) is a safe part, so you can operate with confidence.

4. Before the test, please check whether the control box (station), test transformer, and the ground terminal of the test machine are well connected to the earth.

5.The high-voltage leakage indicator ammeter is only for proofreading, and it is best not to work for a long time.

6. If the instrument is faulty, please contact the company's technical staff according to the telephone number on the manual, and do not disassemble it privately.

7. During use, stop working when only one indicator of battery voltage is on, and charge it in time to avoid battery damage caused by over-discharge. If the battery is not used for a long time, it should be charged once 1-2 months to extend its life. The life of a general battery is about 300 times. It was found that a fully charged battery quickly used the phenomenon of low voltage, indicating that the battery capacity has become smaller, and the battery can be replaced. The battery is a 12V maintenance-free lead storage battery (the same as the electric bicycle battery on the market). To replace the battery, you need to open the upper cover of the testing machine, take out the old battery, replace it with the new battery, and connect the two leads (with inserts) of the old battery to the new battery. Note that the red wire is connected to the positive electrode and the black wire is connected to the negative electrode. Make sure the plug is in good contact.
