Dry-type transformer inspection.

First, check the Dry-type transformer for abnormal sounds and vibrations. Second, check the Dry-type transformer for local overheating, harmful gas corrosion, and other discoloration caused by creepage traces and carbonization on the insulating surface. Third, check whether the air-cooling device of the transformer is operating normally. Fourth, the high and low voltage joints should be free from overheating, and the cable head should be free from leakage and creepage. Fifth, the temperature rise of the windings should be based on the insulation material grade used by the transformer, and the monitored temperature rise should not exceed the specified value. Sixth, the supporting porcelain bottle should be free of cracks and discharge traces. Seventh, check whether the winding compression piece is loose. Eighth, check the indoor ventilation, the iron core air duct should be free of dust and debris, and the iron core should be free of rust or corrosion.

Dry-type transformer protection device.

The Dry-type transformer microcomputer protection device is economical protection for the integration of measurement, control, protection, and communication. The Dry-type transformer is tailored for the high-voltage power distribution room of the distribution network terminal, with three-stage non-directional current protection as the core, equipped with grid parameter monitoring and collection functions, which can save traditional ammeters, voltmeters, power meters, frequency meters, and watt-hours Table, etc. The measurement data and protection information can be remotely transmitted to the upper computer through the communication port, which is convenient to realize the automation of the distribution network. According to the characteristics of the power supply of the distribution network, the device integrates the automatic switching function of the standby power supply, which can flexibly realize the standby input of the incoming line and the standby input of the bus branch.

The Dry-type transformer microcomputer protection device adopts the international advanced DSP and surface mount technology and flexible field bus (CAN) technology to meet the requirements of different voltage levels in the substation, and realize the coordination, digital, and intellectualization of the substation. This series of products can complete the functions of substation protection, measurement, control, adjustment, signal, fault recording, energy acquisition, low-current grounding line selection, low-cycle load shedding, and other functions. Make the technical requirements, functions, and internal wiring of the product more standardized. The product adopts distributed protection and measurement and control devices, which can be installed in a centralized group or distributed, and the configuration can also be changed according to user needs to meet the requirements of different schemes.
