◆ Product Overview
The AT-ZCK-3000 series products are widely used in 3-35kV indoor switchgear, suitable for various switchgear such as central cabinets, handcart cabinets, fixed cabinets, and ring main units.
AT-ZCK-3000A has indication functions such as primary circuit simulation diagram, temperature and humidity control, live display and locking, circuit breaker test position, circuit breaker working position, circuit breaker opening and closing status, energy storage, grounding switch status, as well as remote/local, opening and closing, energy storage, lighting and RS485 communication functions;
It also has high brightness large screen LCD Chinese character display function and parameter setting function, which measures and displays the voltage of the secondary opening and closing circuit.
In addition to the functions of AT-ZCK-3000A, AT-ZCK-3000B also has intelligent voice prompt alarm and live human proximity voice prompt functions, as well as automatic lighting inside the cabinet.
In addition to all the functions of AT-ZCK-3000C, AT-ZCK-3000C also has the function of measuring and displaying power parameters such as three-phase current, voltage, active power, reactive power, and electric degree.◆
Main technical parameters
◇ Working power supply: AC220V ± 10%, 50Hz/DC220V/DC110V
◇ Working environment: -20 ℃ to+60 ℃
The LCD displays on-site temperature and humidity values in Chinese characters, and users can set the upper and lower limits of heating/dehumidification according to their needs. When the environmental humidity exceeds the upper limit or the temperature is below the lower limit, start heating,
Stop heating when the environmental humidity is below the lower limit or the temperature is above the upper limit. When the ambient temperature is ≥ 40 ℃, the system automatically stops heating to prevent overheating damage. When the heater is disconnected, the alarm relay outputs (passive)
◇ Exhaust output: When the temperature exceeds the exhaust upper limit value, the exhaust output relay contacts are closed (passive). When the temperature is below the exhaust lower limit value, the exhaust output relay contacts are disconnected
Temperature and humidity control accuracy: temperature ± 1 ℃, humidity ± 5% RH
◇ Simulation indication instructions:
● Circuit breaker status indication (voltage input for opening and closing circuit):
When the circuit breaker is closed and the circuit breaker is intact, the red analog bar lights up
When the circuit breaker is opened and the closing circuit is intact, the green analog bar lights up
● Circuit breaker position indication (passive contact input):
When the working position contacts are closed, the red vertical analog bar lights up
When the test position contacts are closed, the green horizontal simulation bar lights up
● Spring energy storage indicator (passive contact input):
The contact is closed, and the red spring symbol is on, indicating that energy has been stored
Contact disconnected, green spring symbol lit up, indicating no energy storage
● Grounding switch position indication (passive contact input):
The contact is closed, and the red vertical analog bar lights up, indicating that the grounding is closed
When the contact is disconnected and the green analog bar lights up, it indicates that the grounding is disconnected.
Note: In the event of a power loss, all illuminated indicators do not light up, and the above contact signals are all from the auxiliary contacts of the circuit breaker.
◇ Electrical/Nuclear phase testing (optional)
◇ Operation function:
The device panel is equipped with a closing/opening switch, an energy storage switch, and a remote/local switch; The lighting can be set to manual lighting and automatic lighting. When set to automatic lighting, the cabinet lighting will automatically start when someone stands in front of the cabinet and stops after leaving (time adjustable)
Accuracy of electrical measuring instruments: ± 0.5%
◇ Electric pulse output: Electric meter pulse constant 3200 imp/kwh
◇ Live display LED startup voltage (kV): rated phase voltage × 0.15-0.65
Locking starting voltage (kV): rated phase voltage × 0.65
◇ Relay output contact capacity: AC220V/5A
Communication protocol: Modbus RTU
◇ Power consumption: ≤ 10W
◇ Electrical strength: greater than AC2000V between the shell and the terminal
◇ Insulation performance: greater than 100 Μ Ω between the shell and the terminal
◇ Anti interference: Complies with GB/T17626.8-1998 standard◇ Seismic resistance: 10-55-10Hz 2g 1min
