WZTQ-66A Bidirectional Station User Identification Device

Our company's low-voltage transformer load area user identification device (hereinafter referred to as the "Intelligent Bidirectional Area Identification Device") is a patented product developed based on power line communication technology with zero crossing at the power frequency. This product consists of a transmitter host and a handheld terminal. Users use a transmitter to send phase information and equipment number information to the distribution network on the low-voltage side of the substation, and can accurately receive phase and equipment number information using a handheld terminal within the power supply radius of the substation.

The WZTQ-66A bidirectional substation user identification device is a new generation of highly reliable identification tool that fully meets the needs of substation user identification and phase attribute identification. This product is based on patented power frequency zero crossing communication technology and has strong anti-interference and point-to-point communication capabilities, with a long communication distance.

The WZTQ-66A bidirectional substation user identification device is mainly used in various fields such as substation survey, substation contracting, electricity inspection, production scheduling, and operation and maintenance of distribution networks.

Intelligent two-way substation user identification device, substation user identification device, substation user query device, and business census device.

1. The instrument adopts an aluminum alloy portable integrated box design, which has good mechanical and anti-corrosion properties. The whole machine is lightweight, and the terminal can be placed inside the main box, making it very suitable for on-site carrying and use.

2. Both the terminal and the host are equipped with large dot matrix LCD displays, all in Simplified Chinese, with intuitive operation and background lights, making it convenient to use in low light conditions.

3. The terminal and host can be flexibly configured without any binding relationship, and there is no need to reset during configuration. The host number can be flexibly changed through the keyboard to achieve user identification of multiple distribution transformer power supply areas under complex conditions.

4. The host has a true power supply anti misconnection protection function. When the 220V power supply is misconnected to 380V, the instrument will quickly and automatically cut off the circuit to protect the safety of the instrument and operators.

5. The terminal has a countdown prompt function and sound prompt (after receiving the signal) during waiting, which is very convenient for users to use.

Compared to products based on FSK carrier communication technology, this product has the characteristics of high signal-to-noise ratio, strong signal, and accurate information recognition. Compared with similar products, it has the characteristics of fast recognition speed, no common high voltage string, common cable trench string, common neutral line string, intuitive display, and simple operation.
