Description
Technical field
The utility model belongs to low-voltage distribution technical field.
Background technique
The low-voltage network scale of construction is big, and low-voltage line is often changed, and causes the branch's wiretap and the building Suo Dai head case of 0.4kV busbar
Corresponding relationship entanglement, when building, head case needs interruption maintenance, it is not known that this stops which branch's wiretap of switchgear house, once
Stop the pass that is staggered, mistakenly stop will be caused electric.The method for verifying branch's wiretap and building head case corresponding relationship now is using multimeter, first
A, B, C phase current values for surveying the incoming switch for the building head case that needs to have a power failure, record, switchgear house are then gone to survey each branch line
The three-phase electricity flow valuve (A, B, C phase) of switch, compares, and is with the building head that needs to have a power failure the most similar preliminary judgement of current value
Then case looks for two operation maintenance personnels respectively at building head case and switchgear house, holds clamp on amperemeter, while surveying electric current, put through pair
It is whether consistent with changing rule to observe current value size with Times current value for square phone.
Such method, there are the drawbacks of, additionally, due to current value become in real time according to current power amount first is that troublesome in poeration
Change, it is different to survey the current value time at building head case current value time and survey switchgear house branch switch, the two current value there are error,
Cannot 100% judgement it is accurate.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of low-voltage power distribution station area and precisely has a power failure tester, side
Just it operates and can realize accurate verification.
In order to solve the above technical problems, the utility model adopts the following technical solution: low-voltage power distribution station area precisely has a power failure school
Test instrument, comprising:
Host has current transformer, clock and GPRS module, is detected at switchgear house low-voltage busbar by current transformer

Slave has current transformer, clock and GPRS module, detects incoming switch at building head case by current transformer
Source side three-phase electricity flow valuve is determined the time of acquisition current value by clock, is opened the inlet wire at whole moment second by GPRS module
The three-phase electricity flow valuve of pass and corresponding time are sent to handheld terminal；
Handheld terminal has clock, GPRS module and display screen, and host, slave are synchronous with the clock of handheld terminal, GPRS
Module is communicated with host and slave, the current value and acquisition time that display screen real-time display host, slave acquire.
Preferably, the host and slave are using open type current transformer detection electric current.
Preferably, the clock of the host, slave and handheld terminal uses GPS synchronised clock.
Preferably, the host, slave and handheld terminal are powered using rechargable power supplies.
Preferably, the host, slave and handheld terminal are equipped with 4G SIM card and realize communication.
The utility model by adopting the above technical scheme, has the following beneficial effects:

Powered-down source three-phase electricity flow valuve is simultaneously sent to handheld terminal, the current value acquired by handheld terminal real-time display host, slave
And acquisition time, it is therefore, easy to operate.
2, principle is simple, and there is no interference, precisely verifies；
3, host is modularization grafting design, can survey the electric current of multiple branches wiretap simultaneously；
4, the display interface of handheld terminal can extend display according to the quantity of host automatically.
The specific technical solution and its advantages of the utility model will combine attached in the following detailed description
Figure is described in detail.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and detailed description:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is handheld terminal display screen display interface schematic diagram.
Specific embodiment
The tester refering to what is shown in Fig. 1, low-voltage power distribution station area precisely has a power failure, comprising:
Host has current transformer, clock and GPRS module, is detected at switchgear house low-voltage busbar by current transformer
The current value of branch's wiretap determines the time of acquisition current value by clock, by GPRS module by the branch at whole moment second
The three-phase electricity flow valuve of wiretap and corresponding time are sent to handheld terminal；
Slave has current transformer, clock and GPRS module, detects incoming switch at building head case by current transformer
Source side three-phase electricity flow valuve is determined the time of acquisition current value by clock, is opened the inlet wire at whole moment second by GPRS module
The three-phase electricity flow valuve of pass and corresponding time are sent to handheld terminal；
Handheld terminal has clock, GPRS module and display screen, and host, slave are synchronous with the clock of handheld terminal, GPRS
Module is communicated with host and slave, the current value and acquisition time that display screen real-time display host, slave acquire.
Wherein, the host and slave are using open type current transformer detection electric current.Host uses modularized design, can
To survey multiple branches wiretap load side three-phase electricity flow valuve simultaneously.The clock of the host, slave and handheld terminal uses GPS
Synchronised clock.The host, slave and handheld terminal are powered using rechargable power supplies.The host, slave and hand-held end
End is equipped with 4G SIM card and realizes communication.The display interface of handheld terminal can extend display according to the quantity of host automatically.
In Fig. 1,015 switching current value of branch line is connected to host 2#；024 switching current value of branch line is connected to host 3#.
With reference to Fig. 2, on handheld terminal, can with real-time display host, slave acquire current value and acquisition the moment when
Between, because the comparison of current value is only just significant in synchronization.(note, each phase current of same root cable is in cable head
End and end at each moment are all equal), after receiving data, handheld terminal starts to slave current value and host electric current
Value compares, and when current value is equal, the indicator light on the side of slave and host can be lighted, such as in Fig. 2, the time is all 09
Divide 14 seconds, slave is as the current value of host 2#, it is possible to accurately determine " switch of branch line 015 " and " building T36 head
