A multi-gap self-inflating strong-airflow protective device for lightning protection by longitudinal-blast arc extinguishing. The device comprises a longitudinal-blast arc extinguishing device installed on a grounding terminal of an insulator string (1) via a grounding-side link fitting (2), a grounding-side electrode (5) installed on the longitudinal-blast arc extinguishing device, and a conductor-side electrode (6) installed on an overhead conductor, wherein a protective gap formed by the grounding-side electrode (5) and the conductor-side electrode (6) is parallel to the insulator string (1). The longitudinal-blast arc extinguishing device comprises an arc extinguishing device main body (3) and arc extinguishing tubes (8), wherein the arc extinguishing device main body (3) is provided with several through holes for placing the arc extinguishing tubes, and the angle formed between pairwise arc extinguishing tubes which have ends in contact with each other and are placed in the arc extinguishing device main body is 90°. The arc extinguishing tubes (8) are spirals. The grounding-side electrode (5) is connected to the first arc extinguishing tube via a conductor, and the grounding-side link fitting (2) is connected to the last arc extinguishing tube via a conductor. The device has a simple structure, low manufacturing cost, security and reliability, effectively reduces the lightning tripping rate and accident rate of a power transmission line of an electric power system, and improves the stability of the electric power system.

The invention discloses a novel high-efficiency air pressure valve. The hovel high-efficiency air pressure valve comprises a jacking block, a pressure release block and a mounting block which are mounted and connected from the top down, a plurality of counterweights are mounted at the top of the jacking block, an exhaust jacking block is arranged at the bottom of the jacking block, the bottom of the exhaust jacking block is of a planar structure, the side of the exhaust jacking block is of a downwardly projected cambered surface structure, the pressure release block comprises a jacking section, a first connecting section and a second connecting section sequentially from the top down, the jacking section, the first connecting section and the second connecting section are of an integrally formed structure, the interior of the jacking section is provided with a jacking block-mounting socket, the sidewall of the jacking block-mounting socket is provided with a pressure relief vent, the mounting block is fitted on a second external thread structure of the second connecting section, the interior of the mounting block is provided with an air hole, and the air hole communicates with the air inlet. The upper pressure limit of the novel high-efficiency air pressure valve can be regulated by changing the number of the counterweights on the jacking block, so the novel high-efficiency air pressure valve has a good pressure release control function.

The invention discloses a LED heat dissipation device of a Venturi effect and modification synthetic ejector. The LED heat dissipation device comprises a housing, a synthetic jet actuator, fins and anLED base plate. The LED heat dissipation device is characterized by further comprising a Venturi tube, wherein the fins, the Venturi tube and the synthetic jet actuator are fixedly arranged inside acavity defined by the LED base plate and the housing, so that the position of the Venturi tube and the positions of the fins are relatively fixed; the bottom of the synthetic jet actuator is equippedwith a connecting cover; the connecting cover is connected with the Venturi tube; the outlet of the Venturi tube is connected with the fins; and the housing is fixed with the LED base plate through aslide slot. The invention designs a double-film three-cavity synthetic jet actuator; and the outlet of the synthetic jet actuator is additionally equipped with the Venturi tube, so that flow at the outlet is finally increased. By changing a fluid state and increasing gas inlet amount, heat dissipation efficiency is improved, a junction temperature of the LED is reduced, and the service life of theLED is prolonged.
