Product Description
The main function of the metering connection device is to connect at the T-lead line. It is made of high-strength special aluminum alloy material, designed to solve the problem of copper-aluminum transition. This device has the following characteristics:
Large contact area: provides a stronger flow capacity. Independent self-locking: ensure that the clamping force is constant, improve the stability of the connection.
Exempt from later maintenance: easy to install, reduce maintenance costs and workload.
The shield has a waterproof function: it protects the internal connection from the environment and increases the service life of the equipment. In addition, the upgraded rear wire clamp of the metering connection device is divided into two models, namely JZ-(6-25)/(10-300) and JZ-(3570)/(10-300), to adapt to different use needs
First, what is the power metering device joint wiring?
The joint wiring of the electric energy metering device refers to connecting the current mutual loss device of a number of electric energy metering devices to form a current mutual loss device chain, and then connecting its balance end to the power supply system to realize data sharing and measurement of multiple tables.
Second, what is the role of the joint wiring of the electric energy metering device?
1. Improve the measurement accuracy
Through joint wiring, multiple energy metering devices can measure energy in the same circuit, reducing the impact of environmental and circuit conditions on the measurement error and improving the measurement accuracy.
2. Reduce the device cost
Combined wiring can reduce the volume of the distribution cabinet, reduce procurement and installation costs
At the same time, it also simplifies the management and maintenance of electric energy metering devices.
3. Realize data sharing
Joint wiring can realize the data sharing and exchange of multiple energy metering devices, which is convenient to realize the statistics, monitoring and analysis of electric energy.
Third, how to carry out joint wiring of electric energy metering devices?
The joint wiring of the electric energy metering device needs to be carried out in accordance with certain wiring principles and methods to ensure the correct, reliable and safe wiring.
1. Choose the appropriate current mutual loss device
First of all, you need to choose the right current mutual loss device, which should be combined according to the needs
The number of electric energy metering devices and the accuracy required by the measurement link are selected.
2. Determine the current mutual loss device chain
According to the relative position of the circuit in the series to avoid the current mutual loss device, a more optimized current mutual loss device chain should be designed, so that the power calculation and calibration of each connection point are easy to achieve.
3. Confirm the metering circuit
Confirm that the metering circuit corresponding to each energy metering device corresponds to the position on the current mutual loss device chain.
4. Wiring according to the regulations
In accordance with the specified wiring method, according to the current and voltage terminals of the energy metering device for the correct connection.
Fourth, common problems of joint wiring of electric energy metering device
1. The joint wiring of the energy metering device is prone to the problem of missing reading
In the joint wiring of the electric energy metering device, it is easy to miss the reading problem
It can be caused by the wiring error of the current mutual loss device chain or the fault of the current mutual loss device itself.
2. The error between the power metering devices increases because of the joint wiring
In the joint wiring of the electric energy metering device, if the accuracy of the current mutual loss device is not high or the impedance of the rubber cable is inconsistent, it may lead to an increase in the error between each meter.
Five, summary
Joint wiring of electric energy metering device is an effective method to improve metering accuracy, reduce device cost and realize data sharing. In the process of joint wiring, it is necessary to carry out according to certain principles and methods to ensure safety, reliability and accuracy.
