Description
Technical field
The utility model relates to a kind of overvoltage protection, particularly surge protector.
Background technology
Lightning surge protector (surge Protection Device is called for short SPD) mainly is to limit the transient overvoltage that thunder and lightning causes, i.e. thunder and lightning surge also can limit most switching overvoltage.The thunder and lightning surge can be invaded along power supply or signal inlet wire, and the earth potential counterattack that raises can produce in cable and loop by being struck by lightning building itself or near magnetic field induction in the time of also can be by thunderbolt.Therefore, even good lightning rod, downlead and earth electrode have been arranged, but invade along the line owing to lightning rod can't prevent lightning induction and surge, actual earth electrode is difficult to prevent counterattack, under many circumstances, also needs lightning surge protector.If particularly valuable higher, information electronic device and/or power electronic equipment that impact is larger in the building, ability of its tolerance thunder and lightning surge is significantly less than conventional electric equipment, and the necessity that adopts lightning surge protector is just arranged.
Present domestic lightning protection device market is full of import brand; the technical indicator that the product that has is known as does not reach national standard and the industry standard requirement of China at all through the reality test; the product that also has is obscured the lightning protection concept, and the lightning surge protector of clearance-type, spark gap type is promoted to Chinese user with the appearance of large through-current capacity.In fact this class lightning surge protector can't resolve the afterflow problem of thunderbolt energy at all; the afterflow problem does not solve; will cause puncture short between the phase ground to electrical network, cause ground connection afterflow fault, so that the action of the breaker protection in the current supply circuit and separating brake.
The utility model content
In order to overcome above shortcomings part in the prior art, the purpose of this utility model is to provide a kind of surge protector that can automatically protect electrical network.
In order to reach above-mentioned purpose; the utility model adopts following concrete technical scheme: surge protector; comprise base and be installed in loam cake on the base; the both sides of described base are provided with draw-in groove; outlet terminal and input terminal are housed respectively on the described draw-in groove; outlet terminal is connected by wire with input terminal and is connected with terminal block; described terminal block is installed on the base; be provided with clamp in the described base; on the projection of one end firm banking of clamp; its other end is connected with the fixed leg of base by spring and is stuck in the groove of base, is provided with fixture block in the middle of the clamp, and fixture block is stuck on the centre bore of terminal block.
One end of described clamp is provided with fixing hole, and fixing hole is fixed on the projection of base.
At least two or more form one group of use to described surge protector.
The fixed leg that one end of described spring colludes at base connects, and the other end colludes on the circular hole of clamp.
Compared with prior art; the utlity model has following outstanding advantages and effect: owing to be provided with above structure; the utility model is contained in the voltage switchgear the inside; do not need to adjust data after the installation; directly automatically low voltage electric network is protected; be used for preventing the damage that lightning overvoltage and transient overvoltage cause power-supply system and power consumption equipment, protection equipment and user's safety.Be applicable to various power-supply systems, such as the secondary power supply equipment output end, switchboard and various power consumption equipment.Be widely used in the power supply of the systems such as mobile communication base station, microwave communication office (station), telecommunications room, factory, civil aviaton, finance, security.
