Description
Technical field
The present invention relates to a kind of monitoring system, particularly relate to a kind of rural area low-voltage distribution transformer leading-out terminal residue
Electric current on-line monitoring system.
Background technology
In the rural low voltage network operation maintenance of prior art works, there is the surplus of end in monitoring distribution transforming
Aftercurrent numerical value, has two kinds of implementations: 1, install band residual current data acquisition at distribution transforming leading-out terminal
The intelligent switch of collection function is monitored automatically.Intelligent switch with residual current data acquisition function
Primary structure and operation principle: the intelligent switch of band residual current data acquisition function is exactly in fact
The earth leakage circuit-breaker of one upgraded version, it is on the basis of realizing original creepage protection function,
Add data acquisition and storage function, gathered the residue electricity on circuit by residual current transformer
Fluxion value, and be stored in internal memory, check for user.2, pincerlike residual current table is used to pass through
Manually detect, the primary structure of pincerlike residual current table and operation principle: pincerlike residual current
The most pincerlike leakage current table of table, is when the main tool of pre-test residual current value, and it is by clamping
Shape gauge outfit and table body two parts composition, pincerlike gauge outfit is exactly that a residual current that can arbitrarily close is mutual
Sensor, vises test line gauge outfit, it is possible to obtain remaining power signal on test line, then
By conversion and analysis, finally demonstrate measurement numerical value on the display screen on table body.
There is problems and shortcoming in above-mentioned prior art, such as: 1, uses band residual current data acquisition
The problems and disadvantages that the intelligent switch of collection function brings:
A) intelligent switch monomer cost is big, if simply used in test unit, expense is permissible
Bearing, if popularized in an all-round way, the height of expense is unaffordable.
B) intelligent switch is installed and just have to can be carried out patching operations by open-circuit line, has a strong impact on line
The electricity consumption reliability of user on road, therefore, intelligent switch is usually just pacified before circuit puts into operation
Install.
C) intelligent switch does not the most possess functions of waterproof and dustproof, it is impossible to outdoor installation, it is necessary to install
In regulator cubicle.
D) intelligent switch lacks data network function, and the data that every equipment collects can only be independent
Check, it is impossible on a unified platform, browse the data analyzing all nodes.
E) intelligent switch is belonging to fixing equipment, just cannot withdraw at any time once after installing, without weight
Utilizing function again, input cost is big, so being typically only applied to lay special stress on protecting node.
F) intelligent switch can only gather the residual current data of a road outlet simultaneously, if one
Platform distribution transforming has multichannel outlet, then need to install multiple stage intelligent switch simultaneously, both added installation cost
With, add again installing engineering amount.
2, the problems and disadvantages that the pincerlike residual current watchband of use comes:
A) pincerlike residual current table battery durable ability, it is impossible to support long-time on-line operation
B) pincerlike residual current table is without rainproof function, it is impossible to use in rainy day or wet environment,
And overcast and rainy power supply department exactly is when need most detection distribution transforming leading-out terminal residual current data.
C) pincerlike residual current table data acquiring frequency is low, can only gather the residual current always existed
Data, it is impossible to gather the residual current data of burst.
D) pincerlike residual current table no data network savvy, the data that every equipment collects can only be only
Stand and check, it is impossible on a unified platform, browse the data analyzing all nodes.
E) pincerlike residual current table internal memory is little, it is impossible to support that long playing big quantity stores.
