Technical field
The present invention relates to a kind of field of power distribution, especially a kind of drawer type measuring modular device and power distribution cabinet.
Background technology
The current 400kVA and the following high controller switching equipment for low meter of being directed to includes GGD, GCK, JP cabinet etc., but metering device is equal
For live fixed, i.e. staff must be installed or replaced to scene.Whole device new clothes, rotation need 2 people more than 1 it is small when
Left and right is completed, and scene must configure the safety measures such as ground wire；Rotation class must shift to an earlier date 7 Tian Ans row repair schedule, high-low pressure has a power failure and permitted
Can safety measure can be installed after in place, install also need to carry out site inspection equipment polarity, wiring whether correct, meter
The content such as whether work normally；Exclusions are terminal（Regular or failure）Only rotation, relatively simply, grasps combined connection box
Copper is made in flakes, terminal is replaced.
2nd, there are problem：
1. repair schedule arrangement and power off notifying, palpus site inspection before installing, rotation work must shift to an earlier date 7 days to social public
Cloth, responsible consumer must also notify；Failure accident, power off notifying must be carried out immediately.Meet the peak times of power consumption power failure such as tea frying work difficult
Carry out.
Coordinate 2. having a power failure, be related to CT rotations and installation, whole taiwan area must be stopped, it is desirable to which high and low pressure operation management unit is related
Personnel, which show up to coordinate, to have a power failure, permit operation.The cooperation of O＆M unit is not in place, and power failure work delays, and influences work efficiency.
3. material and Work tool prepare.New clothes and the rotation that expires, after early period reconnoitres, first reconnoitre according to working procedure, open dress
List etc. is received in order, material, is needed to get out required material before going into operation and is used required Work tool.
4. site inspection, whether terminal can work normally, whether CT polarity correct, CT installations group whether correct, two wires
Whether voltage and current circuit is correct.Mistake at one, still needs to correct immediately.
5. the separation of phase colo(u)r streak corresponds to.Currently require A- Huangs, B- is green, C- is red, the black phases of N- and outer layer color BV lines fail entirely
It is corresponding.
6. technological level embodies.Technique that different personnel make is different, system of the same installation personnel in different metering cabinets
It is also different to make technique embodiment.
The content of the invention
The technical problem to be solved in the present invention and the technical assignment proposed are prior art to be improved with being improved,
