Problems solved by technology

It is difficult to carry out power outage work during the peak period of electricity consumption such as fried tea
[0005] 2. Power outage cooperation involves CT rotation and installation, the entire station area must be shut down, and relevant personnel from the high and low voltage operation and maintenance management units are required to be present to cooperate with the power outage and allow operation
The operation and maintenance unit did not cooperate well, and the work was delayed due to power outages, which affected work efficiency

Embodiment Construction

[0050] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051]In order to make the graphics clear and easy to understand, figure 1 , 2 , 3, 4, 5, 7, 8, and 10 are schematic diagrams of removing wires and meters.

[0052] Such as figure 1 , 2 , 3, a drawer-type metering module device, including a housing 101, a transformer 102 located in the housing 101, and a meter 5, the housing 101 is provided with a partition 103, the partition The board 103 divides the housing 101 into an inner chamber and an outer chamber, the inner chamber is provided with the transformer 102; the outer chamber is provided with the meter 5; the housing 101 The back side is provided with a copper bar connection seat 104 that can be plugged into the primary side copper bar 202 . The use of inner and outer chambers improves safety without increasing the occupied volume

[0053] For the convenience of operation, t...

Abstract

The invention relates to a drawer type metering module device, a power distribution cabinet and a maintenance method and belongs to the power distribution field. According to the prior art, high-voltage-side power supply and low-voltage side metering power distribution equipment of 400kVA or below includes a GGD cabinet, a GCK cabinet, a JP cabinet and so on, and metering devices are all on-site fixed type devices, and as a result, the problems of long maintenance time, high complicity and error-proneness will be brought about. The invention aims to solve the above problems. The drawer type metering module device comprises a shell, a mutual inductor arranged in the shell and a meter; a partition plate is arranged in the shell and divides the shell into an inner cavity and an outer cavity; the mutual inductor is arranged in the inner cavity; the meter is arranged in the outer cavity; and the back surface of the shell is provided with a copper bar connecting seat which is in plugging connection with a primary side copper bar. With the drawer type metering module device provided by the technical schemes of the invention adopted, on-site working time can be saved. The plugging-connection module device can be assembled in an office or in a warehouse before the plugging-connection module device is installed, and therefore, power failure loss can be decreased, operation is convenient and safe. The plugging-connection module device can act as a disconnecting switch.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to a drawer-type metering module device, a power distribution cabinet and a maintenance method. Background technique [0002] At present, the power distribution equipment for 400kVA and below includes GGD, GCK, and JP cabinets, but the metering devices are all fixed on site, that is, the staff must go to the site to install or replace them. The new installation and rotation of the whole device takes about 1 hour or more to be completed by more than 2 people, and safety measures such as grounding wires must be provided on site; the maintenance plan must be arranged 7 days in advance for the rotation type, and the safety measures for high and low voltage power failure permits are in place before installation, and on-site inspection is required after installation Check the polarity of the equipment, whether the wiring is correct, whether the meter is working normally, etc.; the except...
