Abstract
The utility model discloses a system for automatically calculating energy consumption of high-voltage electrical equipment. The system comprises a voltage transformer and a current transformer which are connected with a power supply cable, the voltage transformer and the current transformer are connected with an electric quantity sensor, and the electric quantity sensor is also connected with a data display device. When the high-voltage electrical equipment works, parameters of voltage, current, frequency, power, and electric energy of the device can be monitored in real time, the cost of additionally installing an electric energy metering device is reduced, and the system plays an important role in debugging and overhaul of the device.
Description
Technical field
The utility model relates to a kind of system for calculating the high-voltage electric equipment energy consumption.
Background technology
At present, the metering of high-voltage electric equipment energy consumption need to increase extra special-purpose electric energy measuring equipment at feeder ear, the defective of this metering method is, if the user wonders the power consumption of this product, need to go to look into by the powering shelf of service cable end, as increase electric energy measuring equipment on product, be inconvenient to install because volume is larger, and will significantly increase cost of products, therefore this energy consumption measure equipment is not suitable for large-scale popularization.
The utility model content
For the technical matters of above-mentioned existence, the utility model provides a kind of high-voltage electric equipment energy consumption Automatic computing system, need not that powering shelf is checked and with low cost, is convenient to install.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of high-voltage electric equipment energy consumption Automatic computing system comprises the voltage transformer (VT) summation current transformer that is connected with service cable; Described voltage transformer (VT) summation current transformer is connected with electrical quantity sensor respectively; Also be connected with data display equipment on described electrical quantity sensor.
As a kind of preferred, described data display equipment is display.
Usefulness of the present utility model is:
During the work of high-voltage electric equipment, but the parameters such as real-time monitoring equipment voltage, electric current, frequency, power, electric energy, and reduce the extra cost that electric energy measuring equipment is installed, equipment debugging and maintenance are also played an important role.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Mark in figure: 1 service cable, 2 voltage transformer (VT), 3 current transformers, 4 electrical quantity sensors, 5 data display equipments.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1:
The utility model comprises voltage transformer (VT) 2 summation current transformers 3 that are connected with service cable 1; Described voltage transformer (VT) 2 summation current transformers 3 are connected with electrical quantity sensor 4 respectively; Also be connected with data display equipment 5 on described electrical quantity sensor 4, as display etc.
During work, meet by adopting voltage transformer (VT) 2 that the high-voltage signal on service cable 1 is converted to the low-voltage signal that electrical quantity sensor 4 gathers requirement; Large current signal when adopting current transformer 3 with service cable 1 normal operation is converted to and meets the low current signal that electrical quantity sensor 4 gathers requirement.Electrical quantity sensor 4 is responsible for the voltage and current signal is carried out analysis and calculation, thereby draws relevant electrical parameter, and the field bus communication agreement by making an appointment, and each electrical parameter is sent to data display equipment 5 by wire.Finally present with diagrammatic form intuitively.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
