High Voltage Switchgear how storage (1) High Voltage Switchgear now generally use spring operating mechanism, and with spring energy storage; (2) energy release: When the internal high voltage switchgear closing or opening the circuit breaker, the energy storage spring will releasing energy and relaxation; (3) a storage start: When the spring relaxation to a certain extent, control the position of the spring contacts (or ratchet mechanism) will start charging motor, for relaxation of spring energy storage; (4) Storage stop : When the spring is compressed charging motor to a certain extent, control the position of the spring contacts (or ratchet mechanism) will stop charging motor, low voltage switch cabinet principle Wugang City, stopping spring energy; open and close the switch next reserve energy. Category 1, low-voltage switch cabinet 2, 3 AC low voltage distribution cabinet, metal armored away switch cabinet 4 low voltage switchgear fixed-separated 5, 6 high voltage capacitor cabinet, high voltage switchgear low voltage switch cabinet Safety rules 1, on all or part of the disc live work, low voltage, 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 the shorting bar 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, low voltage switch cabinet Yanjin County principle, must be equipped with dedicated switches and fuses. 4.4 secondary circuit when the current test from the secondary side to prevent an anti-PSA, in addition to the secondary circuit breaks, it should also be removed once the fuse. 4.5 secondary circuit is powered on or before the pressure test, shall notify the attendant and associated personnel, and sent to guard the site, Xiping principle of low voltage switch cabinet, 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. Yanjin County, low voltage switch cabinet principle, learning Connaught Electrical and Mechanical (online consultation), low voltage is provided by habit Connaught Mechanical and Electrical Equipment Co., Ltd., Henan. Henan Xi Connaught Electrical Equipment Co. (www.hnxinuo.com) is Zhengzhou, electronics, electrical products processing leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In practice Connaught Electrical and Mechanical leadership with the staff warmly welcome all inquiries negotiations to create learning Connaught Electrical and Mechanical better future.
