Product Description

Quick Detail:Electricity Maintenance Transmission line Intelligent hardware monitoring device

 

Application Background

High-voltage cables, as the blood of the city, provide the energy needed for city life. Once a cable fails, the impact on city life is immeasurable. With the rapid expansion of the size of the power grid and the rapid growth of demand for electricity, society has become increasingly demanding of the reliability of grid power supply. As an important part of condition maintenance, the comprehensive and in-depth application of power equipment live detection (on-line monitoring) technology can timely find hidden dangers of potential operation of power equipment and avoid sudden failures, which is an important guarantee for the safe and stable operation of power equipment. At present, the main detection technologies include partial discharge detection, infrared detection, and ground current detection. It has short-term detection when it is charged, which is different from long-term continuous online monitoring. It has the characteristics of small investment and quick results. Among them, infrared temperature measurement and circulating current detection are widely used. The difficulty in interpreting the results of partial discharge detection technology and the strong professionalism limit the application.
In order to improve the safety of high-voltage cable maintenance and provide a variety of cable live detection methods, it is planned to integrate intelligent monitoring modules on the basis of cable hardware to form intelligent hardware.

Product Principle

The intelligent monitoring module is composed of an electronic detection circuit, which can detect and indicate the charging condition and surface temperature of the cable. The module has the function of energy collection and storage, and can work independently for a long time, reducing the operation and maintenance workload. The module is inserted into the cable fittings in a plug-in manner, which is easy to replace without damaging the electromechanical performance of the original fittings.

Product system architecture

The entire system of the intelligent hardware monitoring module is composed of an energy collection module, a lithium energy storage module, a level conversion module, a live detection module, a temperature detection module, a signal conversion module, a signal processing module, and an instruction output module.

Energizing coil structure

Winding: 0.17mm diameter, 1600 pitches
The core has an inner diameter of 170mm and an outer diameter of 184mm. Core material: 50WW310 silicon steel sheet,
14 laminated sheets; silicon steel sheets are 0.5mm thick and 7mm wide. The ring is formed by joining two semicircles.

Intelligent hardware function description

When the cable current is 0-25A, the system energy is supplied by the lithium battery, and the system power consumption is 4mW at this time. If the cable current is in the 0-25A state for a long time, the system can work independently for 150 days. At this time, in the signal indicating circuit of the system, the green indicator light is always on. At this time, the system energy supply diagram is shown in the figure.

When the cable current is between 25A-120A, the energy of the system is supplied by the lithium battery, and the power consumption of the system is 22mW at this time. If the cable current is in the state of 25A-120A for a long time, the system can work independently for 28 days. At this time, in the signal indicating circuit of the system, the green indicator light is off, the red indicator light is flashing, and the frequency of the red indicator light flashing increases with the temperature of the cable.

When the cable current is 120A-400A, the system energy is taken by the cable power module, and the system power consumption is 35mW at this time. The cable energy taking module not only supplies system energy but also charges and stores energy for the lithium battery. If the cable current is in the state of 120A-400A for a long time, the system can work for a long time. At this time, in the signal indicating circuit of the system, the green indicator light is off, the red indicator light is flashing, and the frequency of the red indicator light flashing increases with the temperature of the cable.

Product Installation

Put a cable on the magnetic ring and wrap a layer of black electrical insulation tape at the joint of the core cross section. Put two semi-circular magnetic rings on the cable, then closely fit together, and wrap one at the joint of the core cross section. Layer black electrical insulating tape to form a ring as shown.

Put two semi-circular magnetic rings on the cable, and then closely fit together to form a ring, and then use electrical insulating tape to wind multiple layers at the two interfaces to form a closed and tight ring, as shown in the figure Show.

Finally, insert the red segment of the control box into the red socket of the magnetic core, and in addition, fix the thermal sensor (green) firmly against the surface of the cable, as shown in the figure.

Features

Built-in 5000mAh high-energy rechargeable lithium battery, with long battery life, suitable for various occasions without power.
Automatic induction charging mode, when the current in the measuring cable exceeds 120A, it will automatically charge, which can provide energy for the device for a long time.
Ultra-low power consumption, 150 days of normal use once charged (when the current is 0-25A).
Use the indicator to identify the live state of the cables that are out of service or live, and quickly locate the cable status.
The whole machine adopts exquisite manufacturing technology, small size and light weight.
