The utility model content
The purpose of this utility model be overcome existing no leakage current lightning protection device for electric power can't modular shortcoming, a kind of no leakage current power lightning protection module is provided.
The utility model solves its technical problem, the technical scheme that adopts is, no leakage current power lightning protection module, comprise votage limit type device and switching mode device, described votage limit type device is connected with the switching mode device, also comprises modular cartridge, is installed in the modular cartridge after described votage limit type device and the switching mode device welding series connection, described votage limit type device adopts 34 * 34 chip varistors, and the described switching mode device employing platinum rhenium 600V/40KA of company diameter is 16 millimeters a gas discharge tube.
Further, also comprise trip gear, described trip gear is connected with the votage limit type device.
Concrete, described trip gear adopts the eutectic welding soldering to connect spring leaf in votage limit type device one end.
Further again, described trip gear is installed in the modular cartridge.
Concrete, described modular cartridge also is provided with the remote signalling mouth.
The beneficial effects of the utility model are, by above-mentioned no leakage current power lightning protection module, the integrated discharge device of two kinds of 40KA of series connection in a modular cartridge, low residual voltage, leakage current, high Uc have been realized, noiseless, long service life, barrier propterty is good, the degree of safety height, and be easy to install and maintain.
Description of drawings
Fig. 1 is the votage limit type device of embodiment and the thickness schematic diagram after the switching mode device welding series connection;
Wherein, 1 is 34 * 34 chip varistors, and 2 is that the platinum rhenium 600V/40KA of company diameter is 16 millimeters a gas discharge tube, and 3 is welding material.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The utility model provides a kind of no leakage current power lightning protection module, the votage limit type device adopts 34 * 34 chip varistors, the switching mode device employing platinum rhenium 600V/40KA of company diameter is 16 millimeters a gas discharge tube, and the votage limit type device connected with the switching mode device be integrated in the modular cartridge, be easy to install and maintain, and can reach leakage current, glitch-free effect.
Embodiment
This example has also been installed trip gear, thickness schematic diagram such as Fig. 1 after its votage limit type device and the switching mode device welding series connection.
The no leakage current power lightning protection module of this example adopts technical scheme described in the utility model, the votage limit type module connected with the switching mode module be integrated in the modular cartridge, wherein, the votage limit type device adopts 34 * 34 chip varistors 1, and the switching mode device employing platinum rhenium 600V/40KA of company diameter is 16 millimeters a gas discharge tube 2.
Because the votage limit type device adopts 34 * 34 chip varistors, its distributed capacitance is 3000pF, leakage current is smaller or equal to 20 μ F, thickness is smaller or equal to 4 millimeters, and the switching mode device employing platinum rhenium 600V/40KA of company diameter is 16 millimeters a gas discharge tube, its distributed capacitance is 5pF, thickness is smaller or equal to 3.6 millimeters, then behind their tandem compounds, too high maximum Uc is distributed on the switching mode device, and adding that welding material 3 welding back thickness can reach below 8.5 millimeters fully, and the modular cartridge inner thickness is 9 millimeters, then can be installed in the modular cartridge fully.This no leakage current power lightning protection module is in holding state, leakage current on power supply protection circuit.
In addition, trip gear has been installed in modular cartridge also, trip gear adopts the eutectic welding soldering to connect spring leaf in votage limit type device one end, connect with the votage limit type device, and modular cartridge also is provided with the remote signalling mouth, to reach the remote signalling function, convenient inspection fault.
