(2) Check that all safety measures comply with the relevant regulations and current safety technology regulations. For equipment whose electrical distance is less than the specified safety clearance, appropriate safety measures should be taken around it, such as strengthening insulation and installing fences, so as to create safe working conditions for the operation and maintenance personnel of the transformer.
(3) Perform a visual inspection of all electrical installations to determine if the quality of the project meets the requirements.
(4) Check the construction of concealed works such as cable trenches, and the laying of grounding devices for cable heads.
(5) Check the interlocking devices of all high-voltage switches. Customers of dual power supplies must also install interlocking devices for string power.
(6) Check if the communication device is installed. For substations of 35kV and above, special telephones are required; for small power customers with power supply of 10kV and below, the telephone number and the person in charge should be clearly identified.
(7) During the intermediate inspection, the customer should be notified to the corresponding accuracy monitoring of the load monitoring instrument and relay protection. Before the equipment is connected to the grid, the relevant tests should be carried out, and the incoming electrician training should be notified; the customer should be required to start with the safety tools. , fire equipment, necessary procedures, management systems and all necessary forms of records.
The Temperature sensor for busbar installed in cabinet is suitable for the temperature monitoring of cable joints, circuit breaker contacts, knife switches, high-voltage cable intermediate heads, dry-type transformers, low-voltage high-current and other equipment in high and low voltage switch cabinets to prevent them from being in operation. Heating due to excessive contact resistance of the contact caused by oxidation, looseness, dust and other factors becomes a safety hazard. This improves equipment safety, timely, continuous and accurate reflection of equipment operating status, and reduces equipment accident rate.
