ZGF2000-60KV/2mA直流高压发生器,高压泄漏试验设备 高压试验装置 0002004002 4300元 12000克

ZGF2000系列直流高压发生器满足国标、行标ZBF24003-90《便携式直流高压发生器通用技术条件》的技术要求,适用于电力部门、厂矿企业动力部门、科研单位、铁路、化工、发电厂等对氧化锌避雷器、磁吹避雷器、电力电缆、发电机、变压器、开关等设备进行直流耐压和泄漏试验,兼做静电吸尘、喷涂等电源,是新世纪最理想的换代产品

    采用脉冲宽度调制(PWM)技术、IGBT、以及先进的电子线路及元件,具有输出不受电网波动干扰,有零位、过流、击穿、过压等保护措施,无论过流、击穿、过压保护电路都能迅速动作,有效保障设备及人员安全。其输出采用液晶显示,体积及重量比原KGF型要轻便的多,非常适合现场使用。全新设计的“0.75U”液晶显示器可直接显示并锁存0.75U1mA现场试验不需人工计算。
    本仪器具有体积小、功率大、重量轻、便于携带、操作方便、安全可靠等优点。
