The CBCT is a variable voltage DC power supply designed specifically to test substation circuit-breaker Open and Close coils. The CBCT uses the substation’s DC power supply to electronically generate a programmable output voltage from 5% to 95% of the source voltage. The CBCT can maintain up to an 80A test current while maintaining 2% or better voltage regulation during the circuit breaker coil operation.
- One continuous and one pulse DC output
- Back-lit LCD screen (20 characters by 4 lines)
- Output voltage programmable from 5% to 95% of the input voltage
- Built-in, single channel timer
CBCT是一种可变电压直流电源,用于测试变电站断路器的开路和闭路线圈。CBCT使用变电站的直流电源以电子方式产生5%至95%源电压的可编程输出电压。在断路器线圈操作期间,CBCT可以保持高达80A的测试电流,同时保持2%或更好的电压调节。
- 一个连续和一个脉冲直流输出
- 背光液晶屏(20个字符,4行)
- 输出电压可编程为输入电压的5%至95%
- 内置单通道定时器

CBCT
输出电压可调的直流供电电源(1个连续直流输出和1个脉冲直流输出)
产品功能和性能:
主要适用于实验现场条件受限,导致无法提供断路器测试用电源,从而替代变电站供电电源给断路器操作回路供电。
产品卖点:
1)使用变电站直流电源(20 – 300Vdc);
2)可调的直流供电电源,用来测试断路器跳闸和合闸线圈的动作电压;
3)输出电压可编辑,大小为装置输入电压源(20 – 300Vdc)的 5 – 95%;
4)有2个直流电压输出可选:一个连续直流电压输出和一个脉冲直流电压输出,且都能输出高达80A电流;
5)内置单通道计时器,可用于验证断路器的时间特性。
