Exploring the operation method and precautions of the large current generator

The large current generator (riser) is based on the size of the output current using a split or one-piece structure, the product is relatively small size, light weight. The large current generator (current riser) also has the characteristics of infinite adjustment of output current, balance of current rise, large range of load change, reliable operation, easy operation and safety. It is the ideal equipment for carrying out a rise or temperature rise test.

The large current generator is a special equipment specially designed and manufactured according to the current load test and temperature rise test of various switches, current transformers and other electrical equipment in the electrical equipment test by the electric power department and industrial and mining enterprises.

Operation method of large current generator 1. Connect the circuit according to the working principle diagram. Transformer enclosures, consoles, etc. must be well grounded.

2. Turn on the power supply. The green indicator light on the high current generator (riser) console is on. Press the start button again, and the red indicator light will be on, indicating that the current riser is waiting for the up flow.

3. The large current generator rotates the voltage regulator evenly clockwise so that the output current indicates up to the required large current. In order to ensure the test accuracy, a standard ammeter can be connected in series with the instrument string.

4. In the test of large current generator, once an abnormal situation occurs, the power supply should be cut off immediately and the cause must be ascertained before testing.

5. After the test is completed, the regulator must be reset to zero position. Press the stop button to cut off the power supply; cut off the power supply before removing the test wiring to ensure safety.

The use of high-current generator Note 1, in use, the current transformer and console must be reliably grounded, ensure safety.

2. New installations and transformers that are not used for a long period of time. Before operation, the insulation resistance between the measuring coils and the coil-to-ground insulation resistance of the 1500 megohmmeters produced by Top Electric may be used only when the resistance value is not less than 0.5 megohms.

3, high current generator (riser) designed for short-term work, it is not allowed to work under rated capacity for a long time, in particular, does not allow more than rated current operation to prevent overheating.

4. The contact surface between the regulator and brush should be kept clean. It can be wiped clean with 90% alcohol and cotton yarn as the case may be.

5, when the rise should be slow and even, when moving should avoid excessive vibration.

6, large current generator (riser) should be stored in a clean, ventilated, dry place.

The fluorinated mica crystals have very good high temperature resistance, corrosion resistance and light transmission properties, and can work for a long time at a high temperature of 1100°C.

No reaction occurs with strong acids and alkalis; complete light transmittance (pure and transparent). The natural mica plates traditionally used in the observation window of high-pressure boiler water level gauge are all brown, and the light transmittance is not good, and the temperature resistance is in the range of 200-700°C, especially the corrosion resistance is poor. The boiler steam drum water in thermal power plants contains alkali. After reacting with natural mica and alkali, it is washed with hot air and hot water, and it is prone to fluffing, scaling, and being broken. In the short term (about 1-2 months), the water level is not clearly understood. After being broken, it can easily cause leakage. The fluorite mica does not react with the acid-base solution, and does not react with water in the hydration reaction, so that it does not form a layer, does not scale, and does not break. In the long-term (2 to 3 years) scouring of high-temperature and high-pressure water (including acid and alkali), the original clarity and transparency can still be maintained. In China, it has been widely applied to the observation window of steam boiler water level gauge in high-pressure boilers of thermal power plants. It has also been selected by Japanese BBK company and NDK (Colin) company for the observation window of high pressure boiler drum level gauge.
