JCQ-3 (YC)10/800D Communication-Type Lightning Arrester Monitor

I. Product Brief

This product is a new type of monitor developed and designed by our company on the basis of the original JCQ-3A10/800 D-type surge arrester on-line monitor. On the traditional current monitoring circuit, we have added electro-optic converter, optoelectronic isolation, optoelectronic converter, and add 485 communication interface to achieve long-distance isolated transmission. Therefore, this product not only has the functions of traditional monitor current monitoring display and discharge number display, but also can be connected to the display terminal through the total line, in order to achieve the purpose of long-distance monitoring leakage current, resistive current, number of actions and action time, it is convenient for the user to observe the operation condition of the arrester in time. With the traditional monitor counting and leakage current indication function, increased the use of RS-485 interface modbus communication protocol signal transmission function, including "sampling" and "signal conversion" two module unit, the use of cast aluminium shell sealed in one, to achieve the outdoor operation requirements.

The RS-485 interface data transmission module can be built into the circuit of the arrester monitor to transmit real-time leakage current data, resistive current data, the number of recorded discharge actions and time to the upper monitoring device. Remote monitoring of lightning arrester operating parameters to achieve the digitalisation of the substation monitoring system. Completing the intelligent design of on-line monitoring of lightning arrester operation in unmanned substation.

The max transmission distance can be up to 1000 metres. After the actual network operation assessment, its convenience, reliability are better than the current pointer leakage meter monitoring device, to meet the actual monitoring needs. After the application will end the history of manual inspection records, to achieve the control room remote on the arrester leakage current online real-time monitoring.

II. Range of application

Suitable for on-line monitoring of transmission and substation metallic zinc oxide surge arresters.

III. Structure and character:

1． Electrical principle: lightning arrester monitor is mainly composed of sampling valve, silicon bridge rectifier, high-voltage capacitor, electromagnetic counter, milliamp meter and other components. It is the use of the discharge current through the arrester, in the valve (non-linear resistance) on the voltage generated by the silicon bridge rectifier to charge the capacitor to the electromagnetic counter discharge, each put a record, to achieve the recording of the number of lightning arrester action.

Figure: B-lightning arrester, C-capacitor, J-electromagnetic counter, Z-rectifier bridge, R1-sampling valve, R2 buck current limiting resistor. The electrical principle attached to the figure is as follows:

2．The product shell adopts high-quality die-casting aluminium shell, the external surface of the spray treatment has good corrosion resistance; sealing performance is better than the stainless steel shell, not by the external environment. Internal components have good anti-aging properties, can be applied to long-term operation in the power system.

IV. Product characteristics

No need for voltage signals: high-speed sampling, use FFT algorithm to analyse waveforms. Use harmonic analysis method to calculate surge arrester resistive current, no need to collect voltage signal from PT, so as to reduce the complexity of the system and the amount of engineering;

Passive mode of operation: using the leakage current of the arrester itself to obtain energy, no need to lay cables;

Wireless transmission: communication adopts the State Grid standard low-power communication module. It conforms to the construction specification of ubiquitous power IoT, and does not need to lay communication cables;

Provide online monitoring application APP for lightning arrester, if the substation is deployed with ubiquitous power IoT access node, it can be deployed and configured remotely through the IoT platform of the provincial company;

Comply with the information security requirements of the State Grid, and can quickly access the provincial company's IoT platform and transmission and substation online monitoring system;

Adopts high-precision active zero-flux through-centre transformer. According to the measured current size,automatically select the amplification, achieve high-precision measurement;

Adopts dynamic phase compensation algorithm to achieve high-precision measurement signal analysis;

Digital filtering algorithm, eliminating the "zero drift problem"caused by analogue filters;

Easy to install, flexible configuration, the main equipment can be implemented without power failure.

VI. Installation method and size：

1. When installing, the inclination angle between the monitor panel and the horizontal plane should be less than 85°, so as to avoid the accumulation of water affecting the observation.Use screws to fix the base of the metal casing on the metal support, and grounded through the grounding bus (the monitor base can be used as a grounding bus). The other end of the insulator through the top of the wiring bolt connected to the electrode, with a wire (or aluminium tape) connected to the low-voltage end of the lightning arrester, wiring wire or aluminium row itself should be fixed, can not be allowed to monitor the wiring bolt excessive force, so as not to destroy the sealing of the product lead to product damage.
