Product Description

 

Product Description

During the operation of power grid companies for many years, due to various technical reasons, non-standard management or power and responsibility adjustment, the end-user meter files do not conform to the actual situation, and it is difficult to determine the location of the ground cable power users. Further, the disordered accounts cause that the analysis of line loss rate, distribution network fault location, emergency repair work list issuance and three-phase imbalance analysis and some other advanced applications cannot be effectively carried out. Seriously affected the process of building smart grid by Power Grid Corp.

 

For this reason, Weshine invented the Transformer Area Identifier which based on the high correlation of voltage data of the same electrical energy acquisition equipment, the voltage data of users are clustered to realize the users in the same transformer area. Examples show that the proposed transformer area recognition method can accurately and effectively identify the user transformer area and phase information and reduce the labor and hardware costs. It is of great significance to guide the operation, maintenance, emergency repair, technical renovation and planning of low-voltage distribution network.
 

PRODUCT INFORMATION

TYPICAL APPLICATION

(1) Multi-mode identification method: Three identification modes are optional, which can meet the needs of different sites.
(2) Branch identification: It can determine the electricity branch (switch) to which a user belongs, and the function is more practical.
(3) Phase identification: It can determine which phase a user belongs to in the station area, and the display is intuitive.
(4) Line voltage drop display: The outlet voltage of the host side (low voltage side of the transformer) and the 220V access port voltage of the user under test can be displayed on the same screen, and the voltage drop amplitude on the user's power supply line can be obtained to provide first-hand data for rationally deploying balanced loads. .
(5) Large storage capacity: at least 800 groups of tested user information can be stored, and can be consulted at any time. Data export function: The host has a USB data interface that can export the information of all the tested users, which is convenient for the sorting and statistics of the information in the station area.
(6) The plastic shell of the main unit is made of high-molecular impact-resistant engineering plastic portable outer box, which has good mechanical properties and certain waterproof function, beautiful appearance, light weight, and is convenient for on-site use.
(7) Both the host and the extension use a large-screen dot-matrix liquid crystal display, all displayed in simplified Chinese, and the operation is intuitive and easy to understand at a glance.
(8) The whole machine is equipped with complete accessories, which can meet various needs of different sites.
(9) The multi-mode identification method can accurately determine the distribution transformer area or the branch (switch) of the electrical circuit to which the user belongs. The identification accuracy reaches 100%, the signal strength is high, and the transmission distance is long.
(10) The number of hosts and extensions is flexible. Since the numbers of the host and extensions can be set at will through the keyboard, user identification in the power supply area of multiple distribution transformers (switches) under complex conditions can be realized.
(11) Both the main unit and the extension have a memory function. After setting the working mode once, there is no need to reset the working mode when the machine is turned on again.
(12) It has the function of displaying the port voltage, the user terminal voltage and the line voltage drop on the same screen, which is convenient for comparing the voltage drop and provides a reference for the rational allocation of balanced loads.
(13) Both the main unit and the extension have the function of power supply misconnection protection and alarm prompt function. When the 220V power supply is misconnected to 380V, the circuit will automatically judge and cut off the internal circuit, and at the same time, it will issue a sound and light alarm prompt.
(14) There are two options for the working power supply of the host, the test voltage line is powered by electricity and the external DC power supply module is installed.
(15) The main circuit of the host adopts a high-speed processor with strong data processing capability and powerful storage capability, which can store at least 800 sets of test data, which can be consulted at any time, and the stored data results can be exported through the USB data interface.
