An overvoltage protection assembly, which includes a grounding plate, a mechanical standoff including two upright insulated or non-conducting supports and a conducting member providing a bridge spanning the supports. The mechanical standoff is secured to a top surface of the grounding plate and is insulated from the grounding plate. A plurality of overvoltage-protection modules are connected to each other in series. A first module in the series is fixed in place on the top surface of the grounding plate and the last module in the series is fixed in place on a bottom surface of the bridge. The overvoltage protection assembly is replicated on the grounding plate for each of three phases of service to a power grid and three cables connect each conducting member to a corresponding phase.

Description of the Invention: [Technical Field of the Invention] In particular, the present invention relates to a device for a voltage surge protection device overvoltage protection module. [Prior Art] e The power line between the substation and the wind power plant often has an excessive voltage (excessive V〇ltage). This overvoltage or glitch (four) hidden (four) is from lightning or other factors, wind Turbine _ sudden sensitivity 'and thus glitch can damage the equipment and cause costly downtime. In general, one or more variable resistors (e.g., voltage dependent resistors) are used to protect the wind turbine from damage caused by the surge. In general, the 'variable resistance is directly connected through the AC power line' and the parallel-protection circuit. Variable resistors have a unique electrical and clamp fabrication that reacts to voltages that increase beyond a predetermined voltage. The variable resistors create a low-impedance shunt path for overvoltage currents, with $min = damage to sensitive components due to voltage. In general, the protection circuit is provided with a power fuse, which essentially blows or weakens the fuse. For the moment, low-voltage (2.5 kW) turbines use a no-fuse Raycap lightning surge protection module compared to a traditional transient voltage surge suppressor using a fuse (Transient Voltage Surge Suppressor) The TVSS) array provides a higher degree of protection against lightning and surge currents. Those modules are equipped with a solid industrial 4 201030773 Metal Oxide Varistor (MOV) in the inner casing of the Ming cylinder.

The report cable can be connected directly to a metal oxide varistor. Supply, and internal sink, and eliminate the pressure drop through the fuse. The advantage is that it provides a lower sigh pressure, eliminates glitch when the fuse is broken, and has fewer dimensions. • Power replacement parts. ... material and not for the appropriate metal oxide variable resistor can be used for the use of eve 丨 用 雷 雷 雷 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重 多重SUMMARY OF THE INVENTION The present invention comprises an overvoltage protection assembly comprising a mechanical stand having an upright support and a member for providing a bridge that spans the cut.
