Abstract
The invention relates to a portable unit power utilization metering device, wherein plugs of a current transformer are respectively connected with an electric energy meter; three phases of A, B and C of a voltage wire are respectively connected with VA, VB and VC of the electric energy meter; a zero line is switched in a jack N; and a grounding wire of the current transformer and a zero line of the electric energy meter are respectively led out and are connected with corresponding jacks of the grounding wire and zero line. According to the portable unit power utilization metering device, loss analysis on a low-voltage switch house is farther refined and decomposed, the portable, flexible and mobile metering device is designed and fabricated through the combination of the open type current transformer and the electric energy meter, the power utilization of users in a switch house can be metered in units and sections, the loss analysis on the electric quantity below an evaluation form of the switch-house is divided to the minimum range, a high loss point is positioned accurately, the application is wide, and the device is convenient and easy in use, simple in fabrication and low in cost. Especially, the power stealing behavior using an external line of a power line is prevented, so that the device is very practical.
Description
Technical field
The present invention relates to a kind of electricity consumption WT-MSR, relate in particular to a kind of portable unit electricity consumption WT-MSR, belong to the Electric Application field.
Background technology
For many years, management aspect is pushed in line loss by electric company, deepens continuously to study and inquire into, and has obtained a lot of valuable experience and significant effect.
In the management and analysis of the low district's loss of presenting a theatrical performance as the last item on a programme, serve as the basic unit of examining generally with each low district of presenting a theatrical performance as the last item on a programme.Along with low the deepening continuously of contract work of district of presenting a theatrical performance as the last item on a programme carried out; How to dwindle the field of investigation to greatest extent; Delimit loss zone, locking key customer; Accurately find the high point that decreases, targetedly carry out power utility check, carry out the damage work of falling, be conscientiously to carry out an important topic of pushing analysis, the management of in-depth low pressure line loss always.
In platform district loss analysis; Be according to the electric weight of platform district examination summary table and platform district copy the difference of seeing the electric weight sum with the user; Come counting statistics analysis station district to lose, that is: platform district loss percentage (%)=(platform district power distributing amount-∑ platform user that the district is with copies and sees electric weight)/platform district power distributing amount.
Because the low district institute on-load situation of presenting a theatrical performance as the last item on a programme is different, for a long time,,, be difficult to directly confirm to influence the main position of line loss per unit like the comparatively complicated zone of sub-district, building and power load distribution situation particularly for the more relatively platform district of low-voltage customer.
If in statistical study, can accomplish that the Jiang Tai district loses further decomposition, the loss of Jiang Tai district is determined to a certain unit, a certain section even a certain family, concrete refinement, quantification loss, losing management for the platform district so has extremely important meaning.
Summary of the invention
The present invention is directed to the problem that exists in the above-mentioned prior art, a kind of portable unit electricity consumption WT-MSR is provided, solved main the problem that is difficult to directly confirm to influence line loss per unit in the prior art.
Technical scheme of the present invention is following:
Be set to A, B, C, the wiring of N three-phase and four-line; The current transformer plug is connected with electric energy meter respectively; Pressure-wire A, B, C three-phase respectively with electric energy meter V
A, V
B, V
CConnect; Zero line inserts the N jack; Current transformer ground wire, electric energy meter zero line are drawn respectively and are connected to corresponding ground connection and zero line plug wire hole.
Described current transformer is pincerlike open type current transformer.
Described electric energy meter is the three-phase and four-line electric energy meter.
Advantageous effect of the present invention is following:
1, pincerlike open type current transformer can be measured and contrast multiple electric parameter under the state that does not cut off the power supply.Can not have a power failure, loading and unloading fast are easy and simple to handle under the situation of not taking out stitches.
2, realized low presenting a theatrical performance as the last item on a programme distinguished further refinement, the decomposition of loss analysis; By the combination of open type current transformer and electric energy meter, design and produce into portable, packaged type metering device flexibly, the platform district is with user's subdivision, section electrical measurement; Can table of merit rating following electric quantity loss analysis in Jiang Tai district draw minimum zone; Accurately the location height decreases point, and the wide model of using value and convenient and easy is made simple.Especially to preventing to utilize the electricity filching behavior of power lead external connection, very practical.
3, before the present invention tried to use, loss percentage surpassed more than 9%, and up till now, the low district's loss percentage of presenting a theatrical performance as the last item on a programme has dropped to 8.08% after the examination application, and is further extensive along with what use, still has future bigger falling to decrease the space.With regard to As-Is, estimate through generally applying, to the loss electric weight decompose, refinement, orientation analysis, take two aspect measures of management and technology targetedly, loss can be reduced to below 7%, can reduce loss of enterprises greatly, increase economic efficiency.
4, through height being decreased inspection, metering, the analysis of section; Effectively organize the inspection manpower, in time find the high reason of decreasing, particularly accurately lock the stealing user; For safeguarding normal supply order; The increasing dynamics of opposing electricity-stealing is carried out power utility check work effectively, and more convenient, instrument and condition easily flexibly are provided.
5, because this device can use, guarantee the reliability of power supply on the one hand under live state, guaranteed that the good service of power supply enterprise is promised to undertake, guaranteed the right of the normal electricity consumption of user.On the other hand, avoided reducing, guaranteed to increase confession and extended sales because of the frequent power failure that causes in the inspection makes electricity sales amount.
6, simple in structure, practical, safe and reliable, cost is low, has very strong application value.
