Problems solved by technology

For power strips with lightning protection function in the industry, fuse tubes or thermal fuse tubes are generally inserted in series between the piezoresistive element and the power line, but the small fuse tubes that can be installed in the shell of the power strip generally have a small carrying capacity. In normal ligh...

Embodiment

[0025] Such as figure 1 , figure 2 and image 3 As shown, a lightning protection power strip is composed of a power cord 1 , a casing 2 , a lightning protection module 3 and a multi-channel power output socket 4 . The shell 2 includes a front panel 21, a rear shell 22 and a fixed piece 23; the lightning protection module 3 includes a piezoresistor 31, a temperature fuse 32, an LED light-emitting tube 33, a gas discharge tube 34, a current limiting resistor 35, a PCB circuit board 36, Phosphor bronze spring piece 37 and low temperature solder point 38. The power cord 1 is connected to the lightning protection module 3 and the power output socket 4 inside the casing 2 .

[0026] Such as figure 1 As shown, in the lightning protection module 3, the upper ends of the two varistors 31 are respectively connected to one end of two phosphor bronze spring pieces 37, and the joints are welded with low-temperature solder with a melting point of 140°C; the other ends of the phosphor b...

Abstract

The invention discloses a lightning protection type power extension cord comprising a power line, a housing, a lightning protection module, and a plurality of power output sockets. The lightning protection module and the power output sockets are assembled to a housing panel; and the power line is connected with the lightning protection module and the power output sockets inside the housing. The lightning protection module consists of piezoresistors, a gas discharge tube, an LED tube, a current-limiting resistor, a PCB, temperature fuses, phosphorized copper spring sheets and low-temperature solder points. The piezoresistors and the gas discharge tube form a lightning protection loop; the phosphorized copper spring sheets, the low-temperature solder points, and the low-temperature solder points form a dual release unit and are connected in series into the lightning protection loop; the lightning protection module is connected in parallel between a power line live wire, a zero line, and a ground wire; the dual release unit enables the lightning protection loop to bounce off when the piezoresistors are heated; and the LED tube is connected in series with the current-limiting resistor and then is connected to the piezoresistor sides of the two low-temperature solder points. With the lightning protection type power extension cord, lightning protection of external equipment can be realized and the lightning protection device can also be protected safely.

Description

technical field [0001] The invention relates to the field of lightning protection and power sockets, in particular to a lightning protection power socket. Background technique [0002] With the advancement of society and the promotion of science and technology, people's production activities and daily life are increasingly inseparable from various electrical appliances and communication equipment, so a large number of power sockets in various forms will be used. Most of the power sockets for ordinary civilian use are mainly of plastic shell structure. In the field of industrial power sockets, a standard metal shell structure power strip has been introduced in recent years, which is suitable for power supply of various electric power, communication and instrument cabinets. As an electrical device to prevent induced lightning shock and surge interference, the lightning arrester has been gradually popularized and used. There are already many types of products that combine ligh...
