Safety measures for replacing the insulated terminal on the bottom side of the transformer:

1. Before the construction of the project, prepare the accessories, raw materials, special tools, measuring instruments and insulation products for construction in advance. Safety products must be intact and reliable.

2. All construction teams should understand the construction contents and the characteristics of electrical equipment, and understand the instructions for the use of electric welder equipment and instrument panels and equipment.

3, all registration to participate in the construction team before the construction of the project must study this countermeasure, establish the actual work responsibilities of the project construction, process flow allocation, deadlines, related common problems, and can sign up for the project after the safety measures study training implementation record signature side construction.

4. The dispatching center should be notified early before stopping the closing, and the dispatching center should carry out consistent and harmonious commanders.

5. It is necessary to strictly abide by the rules and regulations of stop, test, charge and discharge.

(1) On the lever of the isolating switch (power switch) and the isolating switch that can be closed to the working address once the gate is closed, the suspension should not be reclosed. Many people are working! Direction of indication; disconnect any switching power supply that can reverse the switch. After the construction team enters the work, it can't enter other areas outside the construction and move the machinery and equipment and spare parts that are irrelevant to the construction.

(2) Before the electroscope is inspected, it is necessary to carry out the test of the gas concentration in the substation area by the CBM patrol teacher, and determine that the gas concentration is below 1? A relative level of electroscope should be applied. Before the electromechanical equipment, the test should be carried out on the electrical equipment to determine the excellent electrical test; the pressure side inspection must wear insulated gloves and wear insulating boots.

(3) After the responsible person in the work has determined that the transformer has no working voltage, the short-circuit grounding wire should be placed on both sides of the transformer. When installing the wire connector, it must be carried out by two people, and one person actually monitors one person. When installing the wire connector, be sure to connect the grounding device end and the power cable end. When the wire connector is removed, the program flow is again. The wire connector must be fixed to the electrical conductor with a special type of wire clamp. It is forbidden to carry out the grounding device or short circuit fault by coiling.

6. Open the wiring chamber of the bottom side of the transformer and the front end development cover, check the insulation terminal and the burnt-out level of the connected line. If there is burnt line on the connecting line, the burnt line will be cut off, and the hydraulic clamp will be used to restrain the 600A wiring nose as the connecting line head. .

7. Apply the screw to the insulated terminal in the wiring cavity on the bottom side of the transformer, and tighten the screw to ensure that the connecting wire is fixed and firm, and the screws are tightened.

8. After the completion of the project construction, the responsible person and the safety responsible person must check the staff, special tools, raw materials and spare parts, and clearly and accurately remove the wire joints at the rear side; after checking all the normalities, the responsible person at work Production scheduling report.

9. After the normal completion of the delivery of the substation staff, the work address can be withdrawn.
