How to use DC high voltage generator
The DC high voltage generator is an instrument that provides a high voltage DC source. The instrument must be grounded reliably before using the instrument. Workers using DC high-voltage generators must have professional personnel for "high-voltage test appointment cards." The use of DC high voltage generators requires the user to press 168 of the "Safety Regulations" and install two distinct disconnect points before the working power enters the tester. When changing the test sample and wiring, the two power disconnect points should be disconnected first. At the same time, at least three staff must be on site to ensure the safety of users. Before turning on the power on the instrument, be sure that the DC high-voltage generator is connected to a 220V AC power supply. Check carefully whether the wiring is correct, and check whether the wiring of the high-voltage discharge rod is reliable. The buck-boost process in the DC high-voltage generator should be maintained slowly and slowly. One of the most important points of prolonging the service life of the DC high-voltage generator is to increase the pressure steadily. Also try to avoid excessive use of the instrument. At the end of each test, the potentiometer is first returned to zero position, and then the power is cut off to discharge the test object. The discharge process is divided into two steps. The discharge of the large-capacitance sample is applied to the ZS-specific discharge resistance bar. Discharge. Discharge rod can not be immediately exposed to the sample, should first gradually close the discharge rod sample, to a certain distance air gap began to discharge, there is a hum, when there is no sound discharge rod discharge, and finally directly connected to the ground Discharge. When the DC high voltage is 200 kV and above, although the tester wears insulated shoes and is located outside the safe distance, due to the influence of the HVDC ion space electric field distribution, several nearby standing human bodies have different DC potentials. . The test personnel should not shake hands or touch the grounding body by hand, otherwise there will be a slight electric shock phenomenon. This phenomenon is more obvious in dry areas and winter, but due to the small energy, it will not cause harm to the human body. DC high voltage generator control box power supply AC AC220V ± 10%, 50Hz. If the power supply is isolated by 1/1 or if spontaneous power is used in the field, the power supply must be connected to earth ground.
How to maintain 1. Replace the hydraulic oil and clean the tank for half a year. The recommended model must be used for the oil.
2. When the gas is hot, check whether the cooling device starts automatically when the oil temperature is ≥45°C. (Cooling water temperature must be less than 30 degrees)
3. Clean the air filter while cleaning the fuel tank. Day 4. Always check the oil filter signal light of the DC high voltage generator. The signal light is on (simultaneously the buzzer will sound), and immediately clean the oil filter.
5. According to the regulations, the lubrication points of the machinery transmission part of the equipment need to be filled with oil;
6. Observe the liquid condition frequently. When the liquid level is close to the lower limit, please add the recommended hydraulic oil to the tank.
7. Regularly inspect the dustproof devices in various places and find that they are damaged or the connections are loose. They should be treated in time to prevent dust from mixing in and damage the equipment.

Hammer Drill, also known as a percussion drill or Impact Drill, is a power Tool used chiefly for drilling in hard materials. It is a type of rotary drill with an impact mechanism that generates a hammering motion. The percussive mechanism provides a rapid succession of short hammer thrusts to pulverize the material to be bored, so as to provide quicker drilling with less effort. If a hammer drill's impact mechanism can be turned off, the tool can be used like a conventional drill to also perform tasks such as screwdriving.
