For the miniaturization in LED street lamp future, the development trend differed in function i ntegration and client field of employment, the power source surge protector volume in the sector used in the past is large, and without the de-mouth instruction of heat, the problems demand of function singleness solves; For without independent grounding line (only LED street lamp shell; pole ground connection) field of employment; therefore; to some hidden danger that equipment protection and maintenance cause; in order to meet, power source integral is integrated, volume is miniaturized, the needs of maximizes power; require that lightning protection device will meet the ability of security protection surge and anti-overvoltage, use the security performance of surge lightning protection device also to need further raising.
Therefore, carry out brand-new design to conventional power source class surge protection device, this surge protection device is used in the power consumption equipment with power lightning protection function; Adopt design that is through-flow greatly, compact, a large amount of pulse energy short circuits that within the shortest time, release circuit can produce because of lightning induction are released greatly, reduce the potential difference between each interface of equipment, thus the equipment in protective circuit.
Summary of the invention
The technical program road lamp power supply surge protection device is used in the power consumption equipment with power lightning protection function; inner compact list piezo-resistance and the single gas discharge tube of adopting independently places form; be positioned at piezo-resistance arranged outside single-point trip gear and indicating device; there is alarm status and malfunction coefficient function; both the ability of security protection surge and anti-overvoltage had been met; meet again LED street lamp industry small integrated, the growth requirement of high safety performance.
The object of the technical program, will be achieved by the following technical programs:
The technical program road lamp power supply surge protection device, comprises gas discharge tube, piezo-resistance, dropout metal clips, instruction metal clips, pcb board, binding post, inner casing, shell, described gas discharge tube, piezo-resistance, dropout metal clips, instruction metal clips is welded on pcb board, external binding post, described pcb board embeds in inner casing, it is characterized in that: described instruction metal clips one end is fixed in inner casing holddown groove, elastic dropout metal clips one end is reliably welded on pcb board, the bending compressing tablet that the other end has deformation is welded on piezo-resistance center side point place, the instruction metal clips other end that the bending compressing tablet of described dropout metal clips links closely described, one end outer setting of described instruction metal clips has red-label and its own resilient can be relied on to upspring, when there is overcurrent, overvoltage condition in circuit, discharged by gas discharge tube, piezo-resistance because of overload causes overheated after conduct heat to the hot trip point of dropout metal clips of welding, hot trip point scolding tin melts, described dropout metal clips is under the effect of self elasticity of compression, it is separated with piezoresistance electrode, disconnects this path, meanwhile, described instruction metal clips pops up under the active force of self, and demonstrate red warning label signal, this protective circuit is in guard mode.
The application of the technical program structure, its outstanding effect shows as:
1, this technical scheme adopts compact structure and threads off without external force heat and designs, and short trouble automatically disengages, and has operating state and faulty indication, local alarm function, clear and intuitive;
2, adopt pcb board bilayer arrangement to cover copper, ensure the electric current property passed through under application system short circuit condition; Bottom surface, five, side face shell adopts two insulation to ensure enough electric clearances and creepage distance, and after preventing certain one deck breakage, internally charged body contact external metallization equipment or housing, cause external shell charged initiation electric shock risk;
3, this technical scheme circuit leakage current and rate of change little, residual voltage is low, through-current capacity is large, the response time is fast, can make the protection level that product has reached, ensure terminal equipment damage from overvoltage;
Below in conjunction with embodiment accompanying drawing, do further to decompose to embodiment of the present utility model, be easier to make the technical program understand, grasp.
