超低频和振荡波二合一的无局放电缆性能检测装置
摘要：
超低频和振荡波二合一的无局放电缆性能检测装置，属于电力电缆测试领域，本发明为了设计一种电缆振荡波局部放电检测技术或超低频检测二合一装置，实现对电缆局部放电检测。本发明包括电感L、开关、电流源、控制系统、屏蔽盒、层隔板和底座；层隔板架设在底座上方并将垂直空间分为上下两部分，电感L安装在上部空间的层隔板上，开关、电流源、控制系统和屏蔽盒安装在下部空间的底座上；电流源和控制系统叠放在一起，且在底座上的投影位置与电感L在底座上的投影位置重合；开关由多个单个开关叠放构成，开关下方设置屏蔽盒，开关在底座上的投影位置位于电感L在底座上的投影位置的前方；电感L与被测电缆进行电连接。
摘要（英）：

The invention discloses an ultralow frequency and oscillatory wave integrated partial-discharge-free cable performance detection device, belongs to the field of power cable test, and aims to design acable oscillatory wave partial discharge detection technology or an ultra-low frequency detection two-in-one device to realize cable partial discharge detection. The device comprises an inductor L, aswitch, a current source, a control system, a shielding box, a layer partition plate and a base, the layer partition plate is erected over the base and divides the vertical space into an upper part and a lower part, the inductor L is installed on the layer partition plate of the upper space, and the switch, the current source, the control system and the shielding box are installed on the base of the lower space. The current source and the control system are stacked together, and the projection position of the current source on the base coincides with that of the inductor L on the base. The switch is formed by stacking a plurality of single switches, the shielding box is arranged under the switch, and the projection position of the switch on the base is located in front of the projection position of the inductor L on the base; and the inductor L is electrically connected with the tested cable.
