Problems solved by technology
[0003] The existing one-way grounding of the neutral point ungrounded system has the following disadvantages in use. 1. The existing ground fault processing device does not have the function of detecting the grounding state of the device when it is used, and it is easy to cause a short circuit when the grounding occurs. The loss of the system reduces the safety of the device; 2. At the same time, the existing processing device does not have the function of fixing when it is placed and used. When the device is used, it is easy to be unstable due to the influence of external force, which reduces the stability of the processing device.

The invention discloses a unidirectional grounding fault processing device for a neutral point ungrounded system. The unidirectional grounding fault processing device comprises a housing. A base is fixedly installed at the bottom of the housing. An alarm is fixedly mounted in the base, a protection plate is fixedly mounted on the front face of the base, an operation lamp is fixedly mounted on theprotection plate, a mounting base is fixedly mounted on one side of the base, a grounding rod is fixedly mounted on the mounting base, and a grounding base is fixedly mounted on the bottom in the housing. The fixing plate is arranged to be matched with the fixing bolt, and the device can be fixedly mounted after being placed, so that the use stability of the device is improved; a housing is arranged, so that the device can be protected during use, and the safety is improved; a circuit breaker protector is arranged to protect the device during use, so that the safety during use of the device isimproved, and the practicability is improved; and the processing device is more convenient to use, the application range is expanded, and popularization and application are facilitated.
Description
technical field [0001] The invention relates to the technical field of neutral point ungrounded systems, in particular to a one-way ground fault processing device for neutral point ungrounded systems. Background technique [0002] Most of the 6-10kV and some 35kV high-voltage power grids in China adopt the neutral point ungrounded operation mode. Its main features are: when the system is single-phase grounded, the voltage and phase between the phases remain unchanged, and the balance of the three-phase system is not damaged. Therefore, it can continue to operate in a short time, and the neutral point is not grounded. Grounding is required when in use. [0003] The existing one-way grounding of the neutral point ungrounded system has the following disadvantages in use. 1. The existing ground fault processing device does not have the function of detecting the grounding state of the device when it is used, and it is easy to cause a short circuit when the grounding occurs. The...
