Description
Technical field
It the utility model is related to one kind and be used for high pressure measurement draw box mechanism, more particularly to a kind of external high-pressure gauge of calibration signal
Measuring tank.
Background technology
High-voltage measuring box is broadly divided into two kinds for its structure：One kind is metering voltage transformer, Current Voltage
Transformer, electric energy meter, remote telemetry device are integrated into a batch meter, eminence installation, it the advantages of be that anti-electricity-theft ability is strong,
Shortcoming is to be not easy to be found when breaking down or stealing occurs.Another kind is separated using electricity box, contradicts installation, it excellent
Point is that meter reading is convenient, and shortcoming is that anti-electricity-theft ability is weak.It is the first that power supply unit uses at present batch meter, which has more than 95%,
And there is the trend for all substituting second greatly.But in order to effectively prevent stealing, present High-voltage measuring box is all arranged on 3-
On 7 meters of electric pole, meter reading person, patrol officer and electricity inspection personnel can not be perceive intuitively that user whether stealing, also not
It is observed that whether High-voltage measuring box breaks down, can only just be can know that by the annual measurement verification of measurement verification department
User whether stealing, whether batch meter break down.
The content of the invention
The purpose of this utility model is exactly to overcome above mentioned problem, there is provided a kind of external high pressure measurement of calibration signal
Case.
The external High-voltage measuring box of calibration signal of the present utility model, including casing, current-voltage transformer and electric energy meter,
Casing is provided with chamber door, and current-voltage transformer is socketed on outside three-phase power line to be coupled with electric energy meter；Electric energy meter is connected to conversion
Device, converter are provided with LED, the peep hole corresponding with LED are provided with chamber door.
As further improvement of the utility model, described converter includes regulating circuit, filter circuit, mu balanced circuit
And LED；The input of regulating circuit couples with electric energy meter output end, output end has coupled filter circuit, mu balanced circuit successively
And LED.
The external High-voltage measuring box of calibration signal of the present utility model, it is compact-sized, block is tight, anti-electricity-theft ability is strong, it is special
Not Shi He Transformer user use, in the absence of loss on transmission and line loss problem, be capable of complete and accurate metering active energy and
Reactive energy.It transformation can be carried out to existing High-voltage measuring box can significantly save to change batch meter cost, to pass through batch meter
Whether outside LED flicker frequency is found out stolen electric.
Brief description of the drawings
Fig. 1 is the structural representation of the external High-voltage measuring box of calibration signal of the present utility model；
Fig. 2 is the internal structure schematic diagram of the external High-voltage measuring box of calibration signal of the present utility model；
Fig. 3 is electric energy meter and converter connection figure；
Fig. 4 is converter structure schematic diagram；
Fig. 5 is converter circuit figure.
Embodiment
Below in conjunction with the accompanying drawings to the external High-voltage measuring box of calibration signal of the present utility model, it is described further：
The external High-voltage measuring box of calibration signal of the present utility model, including casing 1, current-voltage transformer 2, electric energy meter 3
With converter 5, chamber door 4 is provided with casing 1, current-voltage transformer 2 is socketed on outside three-phase power line to be coupled with electric energy meter 3；
Electric energy meter 3 is connected to converter 5, and converter 5 is provided with LED 9, the peep hole corresponding with LED 9 is provided with chamber door 4
10。
Described converter 5 includes regulating circuit 6, filter circuit 7, mu balanced circuit 8 and LED 9；Regulating circuit 6 it is defeated
Enter that end couples with the output end of electric energy meter 3, output end has coupled filter circuit 7 successively, mu balanced circuit 8 and LED 9.
The external High-voltage measuring box of calibration signal of the present utility model, its specifically used method are as follows：
The present apparatus is installed on high electric pole, staff by see LED can flicker it may determine that whether
There is stealing, current-voltage transformer 2 can detect three phase mains exception when someone's stealing, make the electricity being input in converter 4
Pressure changes, and finally influences whether also to change by the electric current of LDE lamps 9, the flicker frequency of LED 9 is changed,
Experienced meter reading person, inspectorate and electricity inspection personnel be easy for judging whether someone's stealing or High-voltage measuring box
Whether normal work.
