Abstract

The utility model discloses a zero-line longitudinally arranged switch cabinet which mainly comprises a switch cabinet. The bottom of the switch cabinet is provided with an insulated column. Zero lines lead out of the switch cabinet and are connected to a metal plate perpendicular to the ground. One end of the metal plate is provided with a connecting end which is fixed with the insulated column, and the other end of the metal plate is connected to a voltage transformer in the switch cabinet. According to the utility model, as the zero lines are longitudinally arranged, the zero-line longitudinally arranged switch cabinet can effectively save space, is safe and convenient in operation and facilitates electrical inspection by an electroscope for each phase conductor.

Description

The switch cubicle that a kind of zero line is longitudinally arranged
Technical field
The utility model relates to switch cubicle field, the switch cubicle that specifically a kind of zero line is longitudinally arranged.
Background technology
Zero line is the circuit that Circuit Fault on Secondary Transformer neutral point is drawn, and forms loop power consumption equipment is powered with phase line, and generally, zero line, at Circuit Fault on Secondary Transformer neutral point place and ground wire iterative earthing, plays double protection.
Earthed switch in switch cubicle is time to ensure personal safety as maintenance, for a kind of mechanical grounding device of ground connection.When electric equipment is overhauled, for the earthed switch that all will close (or hanging up earth connection) that may power transmission may produce induced voltage to all directions or the power failure equipments of power failure equipments, this is in order to prevent that maintainer from sending a telegram here suddenly when power failure equipments (or power failure working point) is worked, guarantee the reliable and secure measure of maintainer's personal safety, residual charge on the electric equipment that Simultaneous Switching cabinet disconnects, also can be closed ground connection and be discharged totally by earthed switch.
Because the wide size of some switch cabinet is less, be subject to the restriction of switch cabinet structure, zero line contacts with the ground wire of earthed switch.
Summary of the invention
The utility model is not enough for prior art, the switch cubicle that provides a kind of zero line longitudinally to arrange, and the zero line of this switch cubicle longitudinally arranges, safe and simple and facilitate electroscope to carry out electrical verification to each phase conductor in the time of can effectively saving space, operation.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: the switch cubicle that a kind of zero line is longitudinally arranged, mainly comprise switch cubicle,, the bottom of described switch cubicle is provided with insulated column, draws zero line in switch cubicle, described zero line connects metallic plate perpendicular to the ground, one end of described metallic plate is provided with link, and described link and described insulated column are fixed, and the other end of described metallic plate is connected with the transformer in switch cubicle.
The utility model compared with prior art, has following beneficial effect: the zero line of this switch cubicle of the utility model longitudinally arranges, safe and simple and facilitate electroscope to carry out electrical verification to each phase conductor in the time of can effectively saving space, operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1, the switch cubicle that a kind of zero line is longitudinally arranged, mainly comprise switch cubicle 1, the bottom of described switch cubicle 1 is provided with insulated column 3, in switch cubicle 1, draw zero line 2, described zero line 2 connects metallic plate 4 perpendicular to the ground, and one end of described metallic plate 4 is provided with link 5, described link 5 is fixing with described insulated column 3, and the other end of described metallic plate 4 is connected with the transformer 6 in switch cubicle 1.The zero line of this switch cubicle of the utility model longitudinally arranges, safe and simple and facilitate electroscope to carry out electrical verification to each phase conductor in the time of can effectively saving space, operation.
