Embodiment 1

[0022] like Figure 1-4 As shown, a general-purpose switch cabinet automatic phase verification device includes a frame 11 whose size matches the switch cabinet and a chassis vehicle 12 installed at the bottom of the frame 11; the frame 11 is L-shaped, vertical placed, the frame 11 is respectively provided with three groups of detection arms corresponding to the upper and lower circuit joints in the switch cabinet, and each group of detection arms includes two detection arms arranged in parallel up and down; the detection arms include contact arms 2, Aluminum block 3 and sensor 5; the contact arm 2, aluminum block 3 and sensor 5 are connected sequentially from left to right, the right end of the sensor 5 is connected to the inner side of the opening of the frame 11, and the left end of the contact arm 2 is equipped with a moving contact 1; the moving contact 1, the contact arm 2, the aluminum block 3, and the sensor 5 are electrically connected in sequence; the outer side of t...

Embodiment 2

[0028] The difference from Embodiment 1 is that an insulating sheath 4 is installed on the outer side of the aluminum block 3 .

[0029] The working principle of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0031] The difference from Embodiment 2 is that a handle is installed on the right end of the chassis.

[0032] The working principle of this embodiment is the same as that of Embodiment 1.

Abstract

The invention discloses a full-automatic nuclear phase device of a universal switch cabinet. The full-automatic nuclear phase device comprises a rack matching the switch cabinet in size and a chassistruck installed at the bottom of the rack. Three groups of detection arms are connected with corresponding displays and phase comparators and are respectively used for displaying whether upper and lower loops of the switch cabinet are electrified or not, comparing and judging whether phases of each group of loops of the switch cabinet are the same or not, judging the phase crossing situation of each group and judging the phase exchange position; the device is pushed into the switch cabinet after being started, a worker judges and observes outside, the whole process is in an insulating state, the safe working environment of the worker is effectively guaranteed, the process operation is simple, the chassis truck is additionally arranged at the bottom of the device, and the device can slide in the switch cabinet and is provided with a corresponding moving contact connected with the switch cabinet, thereby being practical and convenient; and the worker can quickly finish the nuclear phasework of the switch cabinet without the nuclear phase function in a transformer substation.

Description

technical field [0001] The invention belongs to the technical field of transformer detection, and in particular relates to a universal automatic phase verification device for a switch cabinet. Background technique [0002] With the continuous development of the power grid, 10kV equipment has adopted a large number of mid-mounted armored mobile indoor (KYN) switchgears with compact structure, small footprint, high explosion-proof level, safe operation, and perfect anti-mislocking function. [0003] Because many switchgears in the early stage were not equipped with live monitors with phase verification functions, when the staff performed phase verification work on the switch cabinets, they needed to use instruments to manually connect the upper and lower circuits in the cabinets to judge that it is safe to work in the switch cabinets under high voltage conditions. Risk, and the manual operation is complicated and inconvenient, and the nuclear phase work of the substation canno...
