Electrical European Substation Power Transformers - China

Intelligent integrated substation, In addition to the requirements of the power department in terms of installation, acceptance, handover test, operation and maintenance, pay attention to the following matters:

◆The user shall carefully inspect the goods in accordance with the relevant regulations, and the products that are not installed immediately shall be stored in appropriate places according to the normal conditions of use.

◆The product should be lifted by the bottom of the special spreader, as shown in Figure 2.

◆The product is placed horizontally on a pre-made basis, and then the gap between the product base and the foundation is sealed with cement slurry to prevent rain from entering the cable room, and the high and low voltage cables are connected through the bottom sealing plates of the high and low pressure chambers.

◆The product should be reliably grounded after installation; The two main ground terminals on the channel steel of the power station base, the neutral point of the transformer and the shell, and the pile head under the arrester should be grounded respectively by the installation department.

All grounding devices should share one grounding device with a grounding resistance of less than 4 ohms.

At least two grounding leads should be led from the grounding network to the product.

◆After the product is installed or repaired, the following items should be inspected and tested before being put into operation:

◇Whethe r the substation is clean;

◇Whether the operating mechanism is flexible;

◇Whether the main electrical appliances are flexible and reliable;

◇Whether the electrical auxiliary contact is reliable and accurate;

◇Whether the meter and relay operation are accurate;

◇Whether the ratio and polarity of the instrument and transformer are correct;

◆Whether all electrical installation nuts are tightened, whether the installation is firm and reliable;

◆Whether the bus is well connected, and whether the support insulator and clamp are reliably installed;

◇Whether the setting value of the electrical appliance meets the r equirements, and whether the fuse core specification is correct:

◇Whether the contact points of the main circuit and auxiliary circuit meet the requirements of the electrical schematic diagram.

◆repair

◇All components in the product are maintained according to their respective technical requirements:

◇If the selected transformer is oil -immersed, the oil sample analysis should be checked at least once a year according to the regulations;

◇High voltage side switchgear in operation, after 20 times of load or 2000 times of no load opening and closing operation, should check the contact condition and loss degree of arc extinguishing device, abnormal should be repaired or replaced in time.

◇After the low-voltage switchgear automatically t rips, the reasons for the trip should be checked and analyzed.

After the fault is removed, it can be put into operation again.

◇Lightning arresters should be tested once a year before the thunder storm season；
