Description
技术领域Technical Field
本实用新型涉及控制柜技术领域，具体是一种电气控制柜接地检测保护装置。The utility model relates to the technical field of control cabinets, in particular to a grounding detection and protection device for an electric control cabinet.
背景技术Background technique
控制柜是按电气接线要求将开关设备、测量仪表、保护电器和辅助设备组装在封闭或半封闭金属柜中或屏幅上的设备，其布置应满足电力系统正常运行的要求，便于检修，不危及人身及周围设备的安全。正常运行时可借助手动或自动开关接通或分断电路。故障或不正常运行时借助保护电器切断电路或报警。The control cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of people and surrounding equipment. In normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of fault or abnormal operation, the circuit can be cut off or alarmed with the help of protective electrical appliances.
但是目前学生实训用的电气控制柜，在组装时大多都是独立的控制柜，从而可以方便多个学生单独试验，防止出现其中一个控制柜出现故障使整个实验室的控制柜同时断电的情况，但是在控制柜独立安装时，接地设施无法进行检测，当接地装置没有与地面接触时会存在安全隐患。However, the electrical control cabinets currently used for student training are mostly independent control cabinets during assembly, which can facilitate multiple students to conduct separate experiments and prevent the situation where a failure in one of the control cabinets causes a simultaneous power outage in the control cabinets of the entire laboratory. However, when the control cabinet is installed independently, the grounding facilities cannot be detected, and there will be safety hazards when the grounding device is not in contact with the ground.
