Description

A kind of three-phase load unbalance self-checking device
Technical field
This utility model relates to equipment for power transmission and distribution field, particularly a kind of three-phase load unbalance self-checking device.
Background technology
In recent years, due to city and countryside power grid modification and reinforcement management of power supply and power utilization, the economic and social benefit of power supply enterprise is made to be significantly improved.But some units are strengthening management, while wastage reducing and energy saving, only seen many phenomenons of coming to the surface, and lacked enough attention to about technological improvement aspect.
The three-phase equilibrium of low voltage electric network is exactly one of subject matter perplexing power supply unit always, and low voltage electric network is after 10/0.4KV transformer pressure-reducing mostly, with three-phase four-wire system to customer power supply, is the supply network of three-phase productive power and single-phase load mixing electricity consumption.When the single-phase user of attaching, single-phase load should be balancedly tapped on A, B, C three-phase by power supply department.But in real work and running, the mark of circuit, connect the carelessness of electricity personnel and add due to the asynchronism etc. of the uncontrollable increase-volume of single-phase user, the access of great power single phase load and single-phase load electricity consumption, all cause the imbalance of threephase load.If low voltage electric network runs in the bigger situation of three-phase load unbalance degree, it will have undesirable effect to low voltage electric network and electrical equipment.
Utility model content
The purpose of this utility model is in that to provide a kind of three-phase load unbalance self-checking device, it is possible to is automatically adjusted three compound energy imbalances, has voltage compensating function, and support remote data transmission.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model discloses a kind of three-phase load unbalance self-checking device, include device cabinet, outdoor intelligent compensation correcting unit, voltage compensating device, through having phase three-wire three or three-phase and four-line transmission line in device cabinet, outdoor intelligent compensation correcting unit is connected with phase three-wire three or the three-phase and four-line transmission line of traverse, and voltage compensating device is installed on the loop of outdoor intelligent compensation correcting unit and transmission line composition.
Further, device cabinet both sides are provided with arc opening, and device cabinet front surface is provided with cabinet door, offer some louvres below cabinet door, and device cabinet top is provided with protective cover.
Further, outdoor intelligent compensation correcting unit includes controller, IGBT module, external impressed current transformer and connection line, external impressed current transformer can sense can real-time monitoring system electric current system power information is sent to controller carries out Treatment Analysis, the system power information of Treatment Analysis is converted to current value needed for reaching poised state and is sent to IGBT module by controller, and IGBT module forwards driving connection line to small area analysis phase by mutually defeated for unbalanced big electric current.
Further, the mode of operation of voltage compensating device is analyze the information of voltage collected, and exports inductance current when voltage exceedes the pressure regulation upper limit, reduces voltage, when voltage is lower than pressure regulation lower limit, exports capacity current, booster tension.
Further, also including remote data transmission device, remote data transmission device is connected with outdoor intelligent compensation correcting unit and voltage compensating device by signal line, and data signal is sent to the reception terminal specified by mobile network.
Beneficial effect: this utility model passes through structural design optimization, adopt outdoor intelligent compensation correcting unit, voltage compensating device can be automatically adjusted three compound energy imbalances, there is voltage compensating function, and can increase and join remote data transmission device, support remote data transmission.Through the three-phase load unbalance self-checking device simple in construction of appropriate design, regular maintenance is convenient, and has bigger extending space, is suitable for popularization and application.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.
As shown in Figure 1, 2, the utility model discloses a kind of three-phase load unbalance self-checking device, include device cabinet 1, outdoor intelligent compensation correcting unit 6, voltage compensating device 9 and remote data transmission device 10.
Through having phase three-wire three or three-phase and four-line transmission line in device cabinet 1, outdoor intelligent compensation correcting unit 6 is connected with phase three-wire three or the three-phase and four-line transmission line of traverse, voltage compensating device 9 is installed on the loop of outdoor intelligent compensation correcting unit 6 and transmission line composition, remote data transmission device 10 is connected with outdoor intelligent compensation correcting unit 6 and voltage compensating device 9 by signal line, and data signal is sent to the reception terminal specified by mobile network.
Device cabinet 1 both sides are provided with arc opening 2, and device cabinet 1 front surface is provided with cabinet door 3, offer some louvres 4 below cabinet door 3, and device cabinet 1 top is provided with protective cover 5.
Outdoor intelligent compensation correcting unit 6 includes controller 7, IGBT module 8, external impressed current transformer and connection line, external impressed current transformer can sense can real-time monitoring system electric current system power information is sent to controller 7 carries out Treatment Analysis, the system power information of Treatment Analysis is converted to current value needed for reaching poised state and is sent to IGBT module 8 by controller 7, and IGBT module 8 forwards driving connection line to small area analysis phase by mutually defeated for unbalanced big electric current.
The mode of operation of voltage compensating device 9 is analyze the information of voltage collected, and exports inductance current when voltage exceedes the pressure regulation upper limit, reduces voltage, when voltage is lower than pressure regulation lower limit, exports capacity current, booster tension.
The above, it it is only preferred embodiment of the present utility model, not technical scope of the present utility model is made any restriction, therefore every any trickle amendment, equivalent variations and modification above example made according to technical spirit of the present utility model, all still fall within the scope of the technical solution of the utility model.
