Types and functions of transformer accessories

1. Isolation switches and circuit breakers

Maintenance mode isolation switches are responsible for disconnecting the power, whereas circuit breakers safeguard against overloading and short circuits by automatically interrupting the circuit. Isolation switches and circuit breakers are usually installed at the incoming and outgoing terminals of transformers to ensure safety during maintenance and prevent damage to equipment caused by abnormal currents.

2. Voltage transformers and current transformers

Voltage transformers are used to measure voltage, while current transformers are used to measure current. These two devices are crucial in transformer monitoring, providing real-time system operating status data.

3. Heat sink and fan

During operation, Transformers tend to produce excessive heat, which can lead to overheating if not properly addressed. Fortunately, incorporating heat sinks and fans can effectively dissipate this heat, ensuring the Transformer's safe and efficient operation. These accessories are crucial for ensuring the stable operation of transformers, especially in high-temperature and dense-load environments.

4. Oil level gauge and conservator

The oil level display indicates how much transformer oil is present, while the oil conservation system conserves the transformer oil. The oil degree gauge and conservator are critical for maintaining the suitable degree of transformer oil and avoiding oil leaks.

5. Gas relay and pressure relief valve

Gas relays detect abnormal gases inside transformers, while pressure relief valves can release gases when the pressure is too high. These two devices are crucial for the safe operation of transformers, as they can promptly issue alarms or take measures in case of transformer failures.

The importance and application of transformer accessories

Different types of transformer accessories play an important role in the operation and maintenance of transformers. For example, isolation switches and circuit breakers can control the on/off of circuits to ensure safety during maintenance. Power system stability can be ensured with voltage and current transformers, which offer real-time monitoring and measurement of voltage and current levels, supplying essential data for precise management and control. Radiators and fans can ensure that transformers operate at normal temperatures and extend equipment life; The oil level gauge and conservator can prevent oil leakage or insufficient, ensuring the normal operation of the Transformer; Gas relays and pressure relief valves can take timely measures to prevent accidents from escalating in the event of transformer failures; Lightning protection devices can prevent damage to transformers caused by lightning and improve the safety of the equipment.

In addition, the application of transformer accessories is also very extensive. Various transformer accessories are necessary for different power system parts, including power production, transmission, and distribution. By selecting and reasonably applying transformer accessories, the stability and reliability of the power system can be improved, the probability of faults occurring can be reduced, and maintenance costs can be decreased.

Maintenance and upkeep of transformer accessories

Maintenance and upkeep work is essential to ensure the normal operation of transformer accessories and extend their service life; this includes regularly checking the integrity, cleanliness, oil level, etc., of accessories and replacing worn or aged accessories as needed. In addition, a comprehensive transformer inspection should be conducted regularly to ensure that all accessories are in normal working condition.
