The high-voltage electrical inspection and phase verification mechanism is characterized in that the high-voltage electrical inspection and phase verification mechanism also comprises an input end of a grounding wire and an external electrical inspection and phase verification hole of the grounding wire. Compared with traditional products, according to the high-voltage electrical inspection and phase verification mechanism of the utility model, the grounding electrical inspection hole is added, such that convenience in electrical inspection and phase verification is greatly improved. In usage process, it is not required to open a switch cabinet door or for a user to find an effective grounding point; through an electroscope and the four electrical inspection and phase verification holes, electrical inspection and phase verification can be completed conveniently. In actual operation, the electroscope can be adopted to directly perform secondary electrical inspection and phase verification on the electrical inspection and phase verification holes, and therefore, safety accidents can be prevented.

Technical field
The utility model relates to the aobvious device of a kind of Intelligent switch cabinet behaviour, the high voltage testing nuclear phase mechanism of the aobvious device of especially a kind of Intelligent switch cabinet behaviour.
Background technology
At present the aobvious device of a lot of Intelligent switch cabinets behaviour is provided with the pilot lamp that joins with high-pressure side (A, B, C), and three electrical verification nuclear phase holes.When high-pressure side was charged, the pilot lamp of corresponding phase was bright, thereby illustrated that this phase is charged; Yet when luminous indicating lamp broke down, although high-pressure side is charged, the pilot lamp of corresponding phase did not show, can cause security incident.Be head it off, a lot of products have increased by 3 electrical verification nuclear phase holes, and the electroscope by the outside carries out the secondary electrical verification to electrical verification nuclear phase hole to be confirmed, has increased greatly the reliability of electrical verification, the generation of having stopped security incident.In addition, if the user scene is dual power supply, can also realize nuclear phase by electrical verification nuclear phase hole, greatly facilitate the user.Yet, this present series products all only has three electrical verification nuclear phase holes that represent A, B, C three-phase electricity, because the aobvious device of Intelligent switch cabinet behaviour belongs to cabinet dress instrument, so the user is when carrying out the electrical verification nuclear phase by electrical verification nuclear phase hole, need to open switch cubicle or find a ground terminal nearby toward contact, use very inconvenient.
The utility model content
The utility model mainly solves the problem of the aobvious device electrical verification nuclear phase inconvenience of existing Intelligent switch cabinet behaviour, and a kind of Intelligent switch cabinet behaviour is provided the high voltage testing nuclear phase mechanism of aobvious device, does not need to open cabinet door and can complete easily electrical verification nuclear phase function.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
The high voltage testing nuclear phase mechanism of the aobvious device of a kind of Intelligent switch cabinet behaviour comprises: A phase, B phase, C phase high voltage input terminal, the external electrical verification nuclear phase hole of A phase, B phase, C phase, and the electrification in high voltage pilot lamp of A phase, B phase, C phase; It is characterized in that: the external electrical verification nuclear phase hole that also comprises input end and the ground wire of ground wire.
Further, the external electrical verification nuclear phase hole connection electrical circuit inspection of described A phase, B phase, C phase, the electrification in high voltage pilot lamp of A phase, B phase, C phase is connected in parallel in electrical circuit inspection.
The beneficial effects of the utility model are: do not need to open cabinet door in the utility model use procedure, or do not need the user to seek effective earth point, can complete easily electrical verification nuclear phase function by electroscope and four electrical verification nuclear phase holes.

As shown in Figure 2, the high voltage testing nuclear phase mechanism of the aobvious device of a kind of Intelligent switch cabinet behaviour, comprise: A phase high voltage input terminal 1, B phase high voltage input terminal 2, C phase high voltage input terminal 3, the mutually external electrical verification nuclear phase of A hole 5, the mutually external electrical verification nuclear phase of B hole 6, the mutually external electrical verification nuclear phase of C hole 7, and A phase electrification in high voltage pilot lamp 9, B phase electrification in high voltage pilot lamp 10, C phase electrification in high voltage pilot lamp 11;
The external electrical verification nuclear phase hole 8 that also comprises the input end 4 of ground wire and ground wire.
As shown in Figure 1, the electrical circuit inspection that described A phase high voltage input terminal 1, B phase high voltage input terminal 2, C phase high voltage input terminal 3 electrical verification nuclear phase mutually external with A hole 5, the mutually external electrical verification nuclear phase of B hole 6, the mutually external electrical verification nuclear phase of C hole 7 connects respectively separately is in the electrical circuit inspection that described A phase electrification in high voltage pilot lamp 9, B phase electrification in high voltage pilot lamp 10, C phase electrification in high voltage pilot lamp 11 are connected in parallel on separately.
The utility model is compared traditional product, has added ground connection electrical verification hole, has greatly improved the convenience of electrical verification nuclear phase operation.Do not need to open cabinet door in use procedure, or do not need the user to seek effective earth point, can complete easily electrical verification nuclear phase function by electroscope and four electrical verification nuclear phase holes.In actual motion, can use electroscope directly to carry out secondary electrical verification and nuclear phase to the electrical verification hole, thus the generation of having stopped security incident.
To one skilled in the art, can be expressly understood very much specific embodiment by above explanation.The utility model does not limit therewith, and is all according to technological thought of the present utility model, and the difference of doing on the technical scheme basis changes, within all falling into protection domain of the present utility model.
