Category 1, the low-voltage switch cabinet 2, 3 AC low voltage distribution cabinet, metal armored away switch cabinet 4 low voltage switchgear fixed-separated 5, high-voltage capacitor cabinet 6, the operation of high voltage switchgear low voltage switch cabinet security technology Practice 1 on all or part of the disc live work, equipment maintenance and operation of equipment should be separated in order to clearly marked. 2, there should be a permanent secondary winding current and voltage transformers, reliable protective earth. 3, in the run of the current transformer secondary loop work, should take the following safety measures: 3.1 non-current loop is disconnected. High Voltage Switchgear 3.2 In order to reliably short circuit current transformer secondary winding, you must use low voltage short circuit chip and short routes, prohibit the use of wire is wound. 3.3 prohibit any work on the current transformer circuit and short circuit between the terminals and wires. 4, the operation of the voltage transformer secondary loop work, should take the following safety measures: 4.1 strictly prevent a short circuit or grounding. 4.2 Use insulated tools, wear insulated gloves, if necessary, before the work to stop using protection devices. 4.3 take temporary load, it must be equipped with dedicated switches and fuses. 4.4 secondary circuit current test in order to prevent an anti-PSA from the secondary side low voltage switch cabinet factory, in addition to the secondary circuit disconnect external high and low voltage switchgear, should be removed once the fuse. 4.5 secondary circuit is powered on or before the pressure test low voltage switch cabinet principle, it should notify the attendant and associated personnel, and sent to guard the site, check the circuit before pressing confirm no job. Staff 4.6 Check power protection and secondary circuit, without the permission duty, are not allowed to make any switching operation. Thermal control power supply cabinet detailed thermal control cabinet should be enclosed sheet metal all welded construction, sheet metal thickness of at least 2.0mm. Tank top with a removable rings should thermal control power supply cabinet with bottom feed line, front door type, power Cabinets can be installed separately to be installed in groups, against a wall thermal control power cabinet according to protection class IP54.
