Armored remove AC metal-enclosed switchgear: Usage of this switching device is suitable for 3.6 ~ 12kV three-phase AC 50Hz single busbar and single busbar system, power distribution equipment, mainly used in power plants, small generators by electrical substation secondary mining enterprises and electrical power distribution systems, large high-voltage power transmission and motor starters, etc., to exercise control, protection, monitoring. This switch device complies with GB3906, DL404 and international standards IEC298. The switchgear can be equipped with VD4 type, VB2 type, VS1 type, HVF (Hyundai), EV12 vacuum circuit breaker with push-pull circuit breaker to prevent on-load, to prevent accidental switching circuit breaker to prevent the grounding switch is in the closed position closing the circuit breaker to prevent mistakenly charged compartment to prevent misuse live together when conditions 1, ambient temperature -10 ℃ to + 40 ℃ 2, Altitude: less than 1000m3, humidity relative humidity: average less than 95 days %, the monthly average of less than 90% 4 earthquake intensity does not exceed 8 degrees; 5, ambient air should not be obviously polluted corrosive, flammable gas, vapor, etc; 6, no serious contamination and recurrent severe vibration. 7, when used under normal environmental conditions than specified in this standard GB3906 and consultation by the user and manufacturer. 2, rugged and reliable five anti-interlock device on a closed circuit breaker panel can be operated through the observation window in which you can see the status of the circuit breaker; 3, fully functional trolley, the trolley 100% interchangeability Lightweight, with operation, smooth movement; 4, simple maintenance, easy to install bus and cable Jieshou high voltage switchgear, can lift the transfer car, trolley forward, out of, and transportation is very convenient; 5, all assembled switchgear use deposited aluminum steel, corrosion-resistant, anti-oxidation, the use of multi-fold process, to ensure rigidity and high strength. Measurement accuracy grade configuration: 1, the average monthly electricity consumption more than 5 million KwH and high voltage charging users, or transformer capacity for high-voltage and over 10000KVA billing users must configure 0.2 s level of current transformer; 0.2 voltage transformer ; 0.2 S or 0.5 S level meter. 2, the average monthly electricity consumption over one million kwh and high voltage charging users, or transformer capacity of 2000kVA and above high-voltage charging users everlasting high voltage switchgear, you must configure the 0.2 s level of current transformers, voltage transformers 0.2 , 0.5 s or 0.5 power meter. 3, the average monthly electricity consumption in more than 100,000 kwh and billing users Mingguang high voltage switchgear, or transformer capacity of 315 kVA and above billing users must configure 0.5 s level of current transformers, voltage transformers 0.5 High Voltage Switchgear, 1.0 meter. 4, 315 kVA transformer capacity in the following accounting users, three-phase low-power user, single-phase user, you should configure the 0.5 S-class current transformers, 2.0 meter. Five aspects of the secondary circuit 1,35 kV metering and billing electric energy metering devices below the voltage transformer secondary circuit, should not be installed auxiliary contact and fuse disconnectors. 2, energy metering devices must be configured joint junction box, voltage transformer secondary circuit should direct access to the junction box through a joint meter shall not pass through the terminal block access. 3, the transformer secondary outlet terminals to the joint line junction box terminals connecting wires should be insulated copper wire single; A, B, C phase line and neutral respectively yellow, green, red and color line distinction and phase sequence must shun wiring. 4, the transformer secondary outlet terminals to the ends of the wire joint junction box should be numbered markers, writing should be clear and durable.
