It is higher and higher.Therefore, Guo Wang companies are proposed distribution automation system energetically, both improved power supply quality and power supply reliability,
Expand the ability of power supply, realize the high-efficiency and economic operation of power distribution network, and realizes one of the important foundation of intelligent grid.However mesh
Before, the problems such as equipment alteration is inevitably will appear in distribution, can cause phase change under partial picture, although in the prior art in the presence of
Nuclear phase equipment, but alarmed by indicator light, there is no mutually carrying out for judgement to mistake, and specific mistake mutually also needs
Operating personnel reach scene and carry out phase checking work to switch both sides, increase the complexity of operation, reduce operation
Execution efficiency has seriously affected the characteristics of the convenient of distribution automation system is with automation.
Utility model content：
Technical problem to be solved in the utility model is：It overcomes the deficiencies of the prior art and provide a kind of for solving the back of the body
Part operation needs the phase checking device based on car switch of live nuclear phase problem in scape.
The technical solution of the utility model is：A kind of phase checking device based on car switch, including car body, on the car body
It is provided with three-phase bus nuclear phase arm and three-phase outlet nuclear phase arm, is arranged on the three-phase bus nuclear phase arm and three-phase outlet nuclear phase arm
There is the voltage sensor being acquired to voltage value and angle values, the voltage sensor is connect with logic judgment module, described
Logic judgment module includes signal amplifier, filter and the CPU interconnected, the CPU and segment signal output and communication
Module connects, and the communication module is connect with distribution automation system.
The segment signal output includes liquid crystal display and alarm, and the communication module passes through nothing with distribution automation system
Line is connected through a wired connection.
The utility model has the beneficial effects that：
1, the utility model utilize voltage sensor collection voltages value and angle values, by logic unit get A, B,
Whether C three-phase bus side is corresponding with outgoing line side voltage phase angle, and whether phase is correct, and this judging result is passed through signal output section
The liquid crystal display and alarm divided shows, in addition, and by the original communication module of distribution automation, being conveyed to system
In, it is checked for an operating personnel distant place, it is simple in structure, it is easy to operate, the nuclear phase time of staff is saved, distribution is improved and sets
Standby operating efficiency.
2, the utility model is simple in structure, easy to operate, reduces the danger of car switch scene nuclear phase, improves and match
The operating efficiency of net equipment, meanwhile, it can quickly confirm wrong phase, reduce the tedious work that car switch is pulled out, is sent into repeatedly,
Save the working time of execute-in-place.
3, the utility model can facilitate remote monitoring personnel to check, record by the original communication module of automation.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the phase checking device based on car switch.
Fig. 2 is the connection block diagram of the phase checking device based on car switch.
Fig. 3 is the decision flow chart of logic judgment module.
Fig. 4 is the structural schematic diagram of liquid crystal display.
Specific implementation mode：
Embodiment：Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4.
As shown in Figure 1, be provided with three-phase bus nuclear phase arm and three-phase outlet nuclear phase arm on car body, three-phase bus nuclear phase arm and
It is provided with the voltage sensor being acquired to voltage value and angle values on three-phase outlet nuclear phase arm（Current detection section）, voltage
Sensor is connect with logic judgment module, and logic judgment module includes signal amplifier, filter and the CPU interconnected, CPU
It is connect with segment signal output and communication module, communication module is connect with distribution automation system；Segment signal output includes liquid
Crystalline substance screen and alarm, communication module is with distribution automation system by being wirelessly or non-wirelessly attached.
Its course of work includes the following steps：1), voltage sensor acquisition car switch three-phase bus side and outgoing line side two
Hold the voltage value and angle values on six tunnels.
2), as shown in Figure 3：1. comparing whether both sides voltage amplitude value difference is more than ± 5%：If in the presence of going beyond the scope, directly to
Segment signal output sends out alarm signal；If difference in magnitude is normal, continue to judge phase relation；
2. the bus bar side three-phase voltage phase angle signal that acquisition comes is compared with outgoing line side by CPU respectively, phase angle difference is not
It is correct for phase more than ± 30 degree：If bus bar side and outgoing line side three-phase voltage phase angle are correct, CPU exports correct signal, sends
To segment signal output；If bus bar side and outgoing line side three-phase voltage phase angle all go beyond the scope, CPU output error signals, send
To segment signal output；
If being taken out forward in bus bar side two-phase according to the sequence of A, B, C 3. there is the two-phase phase angle situation that goes beyond the scope
One phase phase angle signal is compared with other outlet side two-phases successively, finds the phase differed with its phase less than ± 30 degree, will
Corresponding signal is sent to segment signal output.
3), as shown in figure 4, segment signal output is made of liquid crystal display and alarm, mainly it is supplied to Field Force true
Recognize, corresponding phase condition is shown according to logic judgment part output signal（Wherein capitalization is bus bar side, and lowercase is
Outgoing line side）：If being connected to phase correct signal, only shown in liquid crystal display " all correct "；If there is A, B two-phase phase dislocation
Accidentally, then the dotted line between A and b is only shown in liquid crystal display；If there is A, C two-phase phase error, A is only shown in liquid crystal display
Dotted line between c；If there is B, C two-phase phase error, the dotted line between B and c is only shown in liquid crystal display；If occurring three
Phase phase all mistakes are then shown in liquid crystal display " all mistakes ".At the same time, as long as there is voltage-phase mistake or difference in magnitude
Larger situation can all trigger alarm module, prompt nuclear phase mistake.
4), the controller switching equipments such as current switching station, power distribution room pass through network connection, communication with power grid electrical power distribution automatization system
