Abstract
The utility model provides a lightning protection analog network dish that uses is moved to naked among frequency track circuit, the problem that solve is: when stronger impact energy invades the inside cable, will discharge between the terminal, stride across the transformer in other words, and then caused the damage to indoor electrical equipment, the utility model discloses a technical essential is: the elementary connector that uses lightning protection analog network dish sets up secondary connector outward as the centre of a circle, the round scope that the radius is greater than 5mm, is provided with two at least elementary terminals that link to each other on the elementary connector, is provided with two at least secondary continuous terminals on the secondary connector. The beneficial effects of the utility model are that: and the transformer link to each other just, electric discharge phenomena takes place between the secondary terminal, when this application reaches 10000V at impact energy, and the transformer link to each other just, between secondary terminal not happening electric discharge phenomena. The utility model discloses still has simple structure, simple installation, characteristics such as reliability height.
Description
Technical field
The utility model relates to frequency shift modulated track circuit anti-thunder technical field, the lightning protection simulation network disk used in especially a kind of non-insulation move frequently track circuit.
Background technology
In current ZPW-2000A non-insulation move frequently track circuit, at indoor, outside cable handing-over mouth, be designed with lightning protection simulation network disk, the indoor design of lightning protection simulation network disk has lightning protection transformer, after outside cable is by thunder and lightning and surge impact invasion and attack, impact energy enters house cable by outside cable, then flows into the earth by the leakage path that lightning protection transformer provides.The primary terminals of base is connected to primary, the secondary end sub-connection of base is to transformer secondary output, distance between the primary and secondary terminal be connected with transformer is weak link, actual test only has 2mm, when stronger impact energy invades house cable, to discharge between terminal, and be equivalent to span transformer, and then damage will be caused to the electric equipment of indoor.
Summary of the invention
The purpose of this utility model is to provide the lightning protection simulation network disk used in a kind of non-insulation move frequently track circuit.
The technical solution of the utility model is: it comprises lightning protection simulation network disk, it is characterized in that: with the primary connector of lightning protection simulation network disk for the center of circle, outside the round scope that radius is greater than 5mm, secondary connector is set, primary connector is provided with at least two elementary connected terminals, secondary connector is provided with at least two secondary connected terminals or the elementary connected terminal be connected with lightning protection transformer primary side and the secondary connected terminal that is connected with lightning protection transformer secondary end is arranged on same total connector, described elementary connected terminal is greater than 5mm with the secondary terminal pitch that is connected.
Compared with existing equipment, the utility model effect is: laboratory test results shows, and place where troops were originally stationed thunder simulation network disk, when impact energy is 5000V, between the primary and secondary terminal be connected, electric discharge phenomena occurs with transformer; When impact energy reaches 10000V, between the primary and secondary terminal be connected with transformer, not there are electric discharge phenomena in the application.It is simple that the utility model also has structure, simple installation, reliability high.
