OLTC On-Load Tap-Changer Online Filter Insulating Oil Purifier ZYL-10(1000LPH)

Application
REXON ZYL-10 intelligent on-load tap-changer online oil filter device is the latest intelligent online oil filter device in China. It is mainly used for circulating filtration of insulating oil for on-load tap-changers of main transformers of 35kV and above. The device can effectively remove the free carbon and metal particles of the oil in the tap changer under the normal operation of the transformer system and can reduce the trace amount of moisture, thereby effectively improving the safety and reliability of the on-load tap changer operation. It reduces the number of power outages, prolongs the maintenance cycle, improves the quality of power supply, and increases the service life of oil. It is an environmentally friendly product that saves energy and reduces consumption.

Working Principle

ZYL-10 intelligent on-load tap-changer online oil filtering device consists of an embedded oil pump motor and two-stage precision filter element, pressure monitoring, microcomputer numerical control unit, electronic and hydraulic multi-stage protection locking unit, fault detection and diagnosis system, temperature and humidity control And the remote monitoring system and other components. When the transformer is in normal operation, the power switch is turned on, and the device periodically or automatically circulates and filters the transformer oil in the tap changer according to the set operation mode. When the filter element is clogged, the system automatically alarms and turns off the motor to stop filtering. There are three modes of operation: manual, automatic and timing. With system clock setting, mode selection, record query, manual, automatic and timed running time setting, default running parameter download, parameter query, tap changer action count, cumulative oil filter time record, oil pump motor phase sequence and overload shortage Phase protection, pressure overload protection and other functions.

Advantages

1. Extend equipment life: Through continuous filtering and purification of transformer oil, impurities and moisture in the oil can be effectively removed, the ageing rate of the oil can be reduced, and the service life of the transformer can be extended.

2. Reduce maintenance costs: Since the online oil filter can handle oil quality problems in real-time, the need for regular shutdown maintenance of the transformer is reduced, thereby reducing the overall cost of maintenance and overhaul.

3. Improve system reliability: Maintaining the good condition of transformer oil helps to improve the stability and reliability of the substation system and reduce equipment failures or shutdowns caused by oil quality problems.

4. Improve safety: By timely detecting and handling problems in the oil, the risk of fire or explosion caused by oil quality problems in the transformer is reduced, thereby improving the operating safety of the equipment.

5. Save energy: Good oil quality helps to improve the working efficiency of the transformer and reduce energy loss caused by oil quality problems.

6. Reduce environmental impact: Through effective oil quality management and pollution control, the discharge of waste oil and pollutants is reduced, reducing the impact on the environment.
