  • Detail

Electroscope is a tool used to check whether high-voltage lines and electrical equipment are charged. It is the most basic safety appliance commonly used in substations. High voltage electroscope usually takes glow as indication signal. New high-voltage electroscope also relies on sound or language as an indication. High voltage electroscope is composed of metal working contact, small neon bubble, capacitor, handle, etc. Next, the editor will introduce the use methods and precautions of electroscope

electroscope is a tool used to check whether high-voltage lines and power equipment are charged. It is the most basic safety appliance commonly used in substations. High voltage electroscope usually takes glow as indication signal. New high-voltage electroscope also relies on sound or language as an indication. High voltage electroscope is composed of metal working contact, small neon bubble, capacitor, handle, etc. Next, the editor will introduce the use methods and precautions of electroscope

how to use electroscope

1. Check the voltage level of the rated voltage of electrical equipment before use, and select a qualified electroscope

2. Self test must be carried out before using electroscope: the method is to press the test button with your finger, the indicator light stops flashing, and an intermittent alarm sound is emitted at the same time, indicating that the instrument is normal. Wear insulating gloves, and the hand fixing ring in the handshake includes the following parts. First, check the electrical equipment. The test should gradually collect the electroscope close to the light-emitting device or the high sounding good performance before confirming that the electroscope self-test system should push the self electroscope button to confirm that the electroscope is complete, and then check the electrical equipment. The test should also be closer and closer?? The equipment under test will electroscope until it touches the conductive device part, and this process has been silent. If the direction of light, he can decide that the equipment is not charged. On the contrary, in the process of approaching, it suddenly emits light or sound, that is, the energization of the equipment stops approaching the junction electrical inspection

3. You must press “ Electricity industry safety regulations ” During the implementation of, the staff shall wear insulating gloves and boots and ensure a safe distance from live equipment

4. For electrical inspection, hold the electroscope part of the ring and the staff below according to “ Safety work order of electric power industry ” According to the provisions of the first pre use inspection, verify that the electroscope really performs well in power facilities

precautions for the use of electroscope

1. The high-voltage electroscope put into use must be an electroscope that has passed the electrical test, and the high-voltage electroscope must be tested regularly to ensure its good performance

2. When using high-voltage electroscope, you must wear high-voltage insulating gloves and insulating shoes, and there must be a special person to monitor

3. Before using the electroscope, you should first check whether the electroscope is good and effective. In addition, you should also check whether the alarm is correct on the live equipment with the appropriate voltage level, and then you can go to the equipment that needs to be grounded for electricity inspection. It is forbidden to use the electroscope with the wrong voltage level for electricity inspection, so as to avoid making wrong judgments during the field test

4. During the electricity test, you must concentrate and cannot do anything irrelevant to the electricity test, such as answering and calling mobile phones, so as to avoid wrong or missed tests

5. The power test of the line should be carried out phase by phase. When the power test of the circuit breaker or disconnector or other maintenance equipment used for connection is carried out, the power test should be carried out on both sides of its incoming and outgoing lines

6. When checking the power of multi-layer power lines erected on the same tower, a priori low voltage, a posteriori high voltage, a priori lower layer and a posteriori upper layer

7. Check the power on the capacitor bank after it is discharged

8. During the electricity test, let the metal working contact at the top of the electroscope gradually close to the live part until the neon bubble shines or sends an audible alarm signal. Do not directly contact the live part of the electrical equipment. Electroscope should not be affected by adjacent electrified bodies, so as to send wrong signals

9. If ladders need to be used during power inspection, solid ladders made of insulating materials should be used, and necessary anti-skid measures should be taken. Metal ladders are prohibited

10. After the power test is complete, the grounding operation should be carried out immediately. After the power test is interrupted for some reason, the grounding is not carried out in time. If it is necessary to continue the operation, the power test must be carried out again

editor's summary: This is the introduction about the use method and precautions of electroscope. I hope it will be helpful to you. If you want to know more about it, you can pay attention to the information
