Description

Signal surge protector based on automatic switching of lightning early warning information and operation method

Technical Field

The invention belongs to the technical field of lightning protection equipment, and particularly relates to a signal surge protector based on automatic switching of lightning early warning information and an operation method.

Background

Since the information age, the requirements for stability and reliability of information communication are increasing, and the requirements for lightning protection of modern electrical and electronic equipment are more and more refined as the protection consciousness of people on lightning damage is strengthened. The use of external direct lightning protection methods such as lightning receptors, downlinks and grounding devices reduces damage caused by direct lightning, and the use of a large number of Surge Protectors (SPDs) of a low-voltage power distribution system improves the capability of a power supply system for bearing electromagnetic pulses. Electronic communication equipment belongs to equipment with higher precision, and the tolerance of a signal transmission system of the electronic communication equipment to overvoltage is poorer, so that in order to improve the tolerance of the electronic communication equipment, a large number of signal system surge protectors are adopted for protecting the overvoltage of the signal transmission system. A surge protector, also called surge protector or lightning protector, is an electronic device for providing safety protection for various electronic equipment, instruments and meters and communication lines.

The signal system surge protector is composed of one or more nonlinear elements, and works between a signal source and a load, and usually needs to be grounded, so that when the signal system surge protector is connected between communication lines, signal transmission is inevitably affected. Li Xiang-Chao, Chen Liang Ying, Zhang et al analyzed adverse effect and cause of adverse effect brought by signal surge protector in communication network through theory and experiment in document "analysis of signal surge protector on signal transmission effect". GB/T18802.21-2016 part 21 of Low Voltage Surge protector: the performance requirements and test methods for surge protectors (surge protectors) of telecommunications and signal networks indicate that: the parameters for measuring the performance of a signal type surge protector mainly comprise: nominal through-current capacity (In), residual voltage (Ures), Insertion Loss (IL), standing-wave ratio, bit error rate, near-end crosstalk, and the like; GB/T18802.22-2019 part 22 of Low Voltage Surge protector: the selection and use guide rules of surge protectors (surge protectors) of telecommunication and signal networks, and GB50343-2012 lightning protection technical Specification of electronic information systems of buildings set certain requirements for the selection of special surge protectors for signal systems, and the aim of the requirements is to hopefully equip the signal surge protectors with the characteristics of large through-flow capacity, low residual voltage, small insertion loss, low standing-wave ratio, small error rate, no introduction of near-end crosstalk and the like for the surge protection work of the signal systems as far as possible.

Based on the above circumstances, currently, researches on a surge protector of a signal system mainly aim at improving the through-current capacity, reducing the residual voltage, reducing the insertion loss, reminding faults and the like. For example, patent "a signal surge protector and its circuit" (patent No. 2017106176326), mainly through the means of using the multistage lightning protection component to cooperate, have proposed a large-current, low residual voltage signal system surge protector and its circuit design method; the patent ' a microwave signal surge protector designed by utilizing transmission line input impedance ' (patent number: 2014102944703) ' proposes a design method of a special surge protector for microwave communication without a lightning protection element for the microwave signal surge protector through a transmission line theory, so that an information source signal with fixed frequency can be transmitted to a terminal without damage after the microwave signal surge protector is additionally arranged; the patent of the temperature on-line monitoring device of the voltage limiting type surge protector based on the thermistor (patent number: 2017207015543) proposes that a polymer positive temperature coefficient resistor (PTC) is used for protecting other main lightning protection components of the surge protector, the characteristic that the PTC has thermal expansion is utilized to simulate a tripping spring window alarm device of a common power supply system surge protector, and an integrated fault indicator is added, so that the domestic signal surge protector can carry out simple fault prompt under the passive condition.

Through the above scientific and technological discovery, in the aspects of improving the through-current capacity of the surge protector of the signal system and reducing the residual voltage, the problem can be solved simply by using a high-capacity and low-residual-voltage lightning protection element, for communication signals with specific frequency, a special signal surge protector can be designed to realize lossless transmission, and for fault prompting, the thermal expansion characteristic of a high-molecular positive temperature coefficient resistor (PTC) can be utilized to perform window popup alarm.

In summary, none of the surge protectors of the prior art has the characteristics of large through current, low residual voltage, no insertion loss, low standing-wave ratio, low bit error rate, and no near-end crosstalk. Therefore, how to gather the above advantages on a surge protector, how to change the traditional design idea of the signal surge protector, how to control whether the signal surge protector is connected to a protected signal line or not by adding a control module and introducing a Narrow-Band Internet of Things (NB-IoT) communication protocol on the basis of the traditional surge protector through thunder and lightning early warning information, and achieving the technical effect that the signal surge protector with automatic switching of the thunder and lightning early warning information hardly has any influence on the transmission quality and efficiency of the signal line when no thunder and lightning activity exists, is a key problem. And because lightning activity is a small-probability event, how to enable the signal surge protector to maintain excellent transmission characteristics in most of time periods is also a problem which needs to be solved urgently by the technical personnel in the field.
