A high-voltage bushing includes a housing and a tube disposed within the housing. A conductor is disposed within the tube. An electrically conductive contact member is connected to the tube and has a first opening to receive and contact the conductor. Accordingly, spark-over between the inner surface of the tube and the outer surface of the draw-lead cable caused by a high-frequency transient is substantially prevented.

The invention discloses a powder film spraying machine, which is formed by high-pressure static ejection gun, a controller, and a powder charging cylinder. The static ejection gun uses internal-arranged high-pressure generator and 5010A / 5010B epoxide resin to fill the U-shaped iron core frame of voltage transformer of high-pressure generator; the control circuit of static controller uses automatic distance-current-voltage control and presets a maximum irradiation current to confirm the best powder charge amount. When the distance between the ejection gun and work-piece reaches the maximum irradiation current, the reduced distance will cause the automatically reduction of output high pressure and ejection current, or else, the output high pressure and ejection current will increase. At the instant of short circuit between the ejection gun and work-piece, the output is reduced to minimum and it will recover to high pressure output to eliminate the problem of sparking after started.

The invention discloses an intelligent control magnetic field full coverage wireless charging desk comprising a desk body. A glass plate is embedded into one side of a desk top laid on the desk body, and a liquid crystal display is embedded into the other side. A transmitting coil is installed in a drawer below the desk top. A transmitting module and a single chip microcomputer connected with each other are arranged on a partition plate below the drawer. A power line is embedded into the desk top, the input end of the power line is hidden in the edge of the desk body, and the output end of the power line is connected with the transmitting module. A power supply method of the wireless charging desk is further provided. The wireless charging desk of the invention carries out charging by means of magnetic coupling resonance, is safe and non-radioactive, and reduces the risk of electric shock. The working state of the transmitting coil is controlled intelligently, and the power consumption is reduced. The wireless charging desk is universal and portable. The transmission of power is independent of the charging interface of equipment, and power supply and charging are more convenient. There is no conductive contact exposed. The desk top is clean and neat, and green and beautiful, and creates a good vision. The space of the table desk is saved fully.

The invention relates to a waste gas treatment box of a mining anti-explosion diesel engine. The waste gas treatment box comprises a box body, a fire barrier, a mounting support, a gas inlet, a gas inlet pipe, a gas discharging port, a gas discharging pipe, a water injection hole, a water discharging hole, a liquid level sensor and a waste gas temperature sensor, wherein the box body is mainly used for storing water, the liquid level sensor is used for monitoring the water level inside the box body, the fire barrier is used for eliminating sparks in discharged gas, the waste gas temperature sensor is used for monitoring the temperature of the discharged gas, and the mounting support is used when connected with an engine. Thread explosion-separation design is respectively adopted by the water injection hole and the water discharging hole, the gas inlet pipe and the gas discharging pipe are arranged inside the box body and communicated with the gas inlet hole and the gas discharging hole respectively, wherein the gas inlet pipe extends from the upper portion of the box body to the bottom of the box body, a furcation structure is adopted by the lower portion of the gas inlet pipe, and a plurality of through holes are formed in the pipe wall of the furcation structure at the lower end of the gas inlet pipe. The waste gas treatment box of the mining anti-explosion diesel engine is large in water storage capacity, the effects of cooling and sound-eliminating can be improved, the contact area of the waste gas and water is enlarged, the gas discharging resistance is reduced, and the sparks are fully eliminated.

The invention discloses a new energy automobile charging interface automatic on-off control method based on the Internet, and belongs to the technical field of charging interface. According to the newenergy automobile charging interface automatic on-off control method based on the Internet, a new energy automobile charging device is included, the charging device comprises a charging gun main body; the charging gun main bodyis connected with a handle and a power supply line;acontaining groove is dug in the end, away from the power supply line, of the charging gun main body;asealing plate is slidably connected into the containing groove; an accommodating shell is fixedly connected to the sealing plate; a charging head is slidably connected into the accommodating shell; the sealing plate isfixedly connected with a hollow insulating rod; a conductor rod is fixedly connected in the hollow insulating rod; the cable is connected between the charging head and the conductor rod, so that the charging head can be automatically separated when the charging device is pulled, the cable is effectively prevented from being pulled apart, the wiring position of the conductor is comprehensively insulated and closed when the charging head is separated, and electric arcs generated at the connection position of the conductor when the device is abnormally disconnected are effectively eliminated.

The invention discloses a pressure relief and explosion-proof container. The pressure relief and explosion-proof container comprises a top cavity, a cover body and a cylinder body, wherein the cylinder body is connected with the cover body; the top cavity is formed in the cover body; a wire mesh is arranged in the top cavity; explosion flow can penetrate through the wire mesh before rushing out the explosion-proof container. It can be seen from the contents that the explosion flow can rush into the top cavity from the cylinder body when an explosion is caused; and moreover, the explosion flowcan penetrate through the wire mesh before rushing out the explosion-proof container; and therefore, an effect of eliminating explosion venting sparks and explosion venting noises is achieved. Therefore, according to the pressure relief and explosion-proof container, sparks and noises in the explosion venting process can be eliminated, and the difficult problems in the field at the present stage is solved.
