Features of high-voltage digital speech sounding nuclear instrument 1. High-voltage digital sounding nuclear phase-analyzer is an electrified test tool for operating high-voltage power lines under the operating voltage, especially for nuclear phase rods directly touching high voltage. High power frequency withstand voltage test. The results show that the insulation performance and safety distance can meet the requirements of the electrical safety regulations.
2. The actual use of the relevant power supply bureau for a long period of time generally reflects that the instrument is safe, reliable, and easy to use. The nuclear phase resolution capability is high and portable.
3, the instrument after a certain high-pressure calibration, but also for measuring high voltage.
How to Use High-Voltage Digital Phono-Phase Detector 1. Self-test to determine whether the phase instrument is good.
Insert the test lead into the instrument socket first, and insert the other end into the 220V power supply. At this point, there are three reactions as described in Table 4; if there are three reactions, it is good. If there are no three reactions, there is a problem and it cannot be used.
2. Use a multimeter to check if the high voltage connection is conducting.
3. Test header matters:
The above method for detecting the nuclear phase meter is normal, and it can be formally nuclear. If it is known that the nuclear phase meter is normal, it can be used without detection. If there is no voltage indication during the test, the battery voltage is insufficient and the battery should be replaced. The instrument case can be opened and replaced with a new 9V laminated battery. Note: When the battery voltage is lower than 6V, there is no sound prompt, as long as the voltage is not lower than 4.5V, it can be displayed correctly.
4. Connect the high voltage connection as follows:
5. Prediction of nuclear phaser:
Before the official nuclear phase, the nuclear power system can be tested in the same power grid system. One person touches one of the sticks and one of the electrical conductors, and the other contacts the sticks one by one in the same grid electrical conductor. There are three reactions in the different phases described in Table 4 and no three reactions in the same phase. Then you can officially nuclear phase.
6. Official operation:
The nuclear phase operation should be carried out by three persons, two people operating and one person monitoring. It is necessary to operate one by one, record one by one, and determine whether or not the phase is based on the “three, three, and none†described in Table 4. The nuclear phase operation should seriously implement the rules and regulations formulated by the unit.
7. Keep safe:
During operation, the human body must not touch the nuclear phase meter, high voltage connection and grounding wire, and must maintain a safe distance.
High-voltage digital speech sounder Notes 1. The high-pressure phasing device A and B should be grounded separately, and the grounding of a certain bar should be stopped during the work, and then the measurement should be made after connection.
2. The high-pressure phasing device should be placed in a dry place to inspect the insulation resistance value regularly, and the 35KV phasing device can be hooked to the ground about 60M. The 6-10KV phaser is 27 or so.
3. It is best to have four people working in the field, but not less than three. Fill in the second job ticket.
4. In the design of high-pressure phasing devices, metal bare parts have been reduced as much as possible, but work should still focus on high-mindedness to prevent line short-circuiting and grounding accidents.
