Substation inspections

1) high-voltage substation equipment inspections points to normal sexual inspect, the particularity of inspections, monitoring the inspections and lights-out inspections.
The normal sex patrol duty attendant on the whole the equipment to conduct a comprehensive and detailed examination, the purpose of the timely detection of new defects and monitor changes in the old defective. In addition to the daily shift check check every day must the equipment to a tour of inspection, and test results entered in thin volumes of a variety of records, shall, when necessary leadership report.
The particularity of the inspections in high winds, snow, fog, lightning after bad weather and cold, Kushu and high-load, peak load conditions and targeted to check the occurrence of abnormal operation or equipment maintenance. Attendant related equipment .
Monitoring of sex visits by leading cadres, technicians and attendant equipment inspection, aimed at making government understand the equipment operating conditions, and the work of the staff on duty to evaluate and suggest improvements.
Lights inspections should be carried out every day once.
2) Each substation shall determine its own scientific inspection tour route and the approval of superiors and make the necessary sign at the substation ground. In addition to the particularity of inspections, under normal circumstances. Equipment inspections are should the inspection tour route.
3) approved by the leaders of the unit allows the attendant separate inspections of high voltage equipment and non-duty officer to patrol the high voltage equipment shall not carry out other duties; not climb high voltage equipment and remove, or over the cover bar. If necessary, remove the cover bar must have a guardian present, and the distance between the officers and charged equipment shall not be less than the provisions of the electrical safe work procedures in a safe distance (10kV and below 0.7m, 35kV lm) .
4) during a lightning storm inspections of outdoor high-voltage equipment, patrol officers should wear insulated boots, and not close to the arrester and lightning rod.
5) The grounding of high voltage equipment, indoor shall close to the fault point 4m or less, outdoor shall not be close to the fault point 8m within (staff access to the range must wear insulated boots and wear insulated gloves when contact with the shell and framework).
6) previously entered with the SF6 (sulfur hexafluoride) equipment room visits, should the indoor ventilation to prevent poisoning.
7) visited the power distribution unit and out of the hyperbaric chamber, must be readily locked to prevent small animals.
8) the transformers special inspections project:
① load, should monitor the load, oil temperature and oil change, connector contacts should be a good warm wax melting phenomenon, the cooling system is operating normally.
② There are strong winds, observe the lead twist, and whether to take the hanging debris.
③ thunderstorms, porcelain casing with or without discharge or flashover discharge counters with or without action.
④ fog porcelain casing with or without discharge or flashover, key monitoring filthy porcelain part.
(6) snow weather, according to the parts of the snow melting checks connector fever timely processing of the Popsicle.
⑧ short circuit, you should check the relevant equipment and connectors with or without abnormal.
