Embodiment Construction

[0009] In Fig. 1, the electric switch is a switch used in the prior art to connect or disconnect the circuit, and there are single-phase, three-phase, alternating current switches and direct current switches according to different circuit properties. The photoelectric receiver in Fig. 1 can be used in stereotyped products or can be designed by oneself. A cable mixed with metal wires and optical fibers, the metal wires are used to transmit electrical energy, and the optical fibers are used to transmit optical signals, specifically to transmit cable fire signals. The system is composed as follows: a cable mixed with metal wire and optical fiber, the metal wire in the cable is connected to the electrical switch, the optical fiber in the cable is connected to the photoelectric receiver, and the photoelectric receiver is put together with the electrical switch.

[0010] In Figure 2 the electrical switch is the same as in Figure 1 . The system is composed as follows: a cable mixed ...

Abstract

This invention relates to a method for supplying utilizing mixed cables of metal leads and fibers, which is used in transmiting electric energy and optical signals, especially transmitting cable fire signals to control fire by photoelectric control, in which, single-mode fiber of glass fiber or plastic fiber is applied for fibers of the cable, apart from a traditional electric switch for turning on / off a circuit, a photoelectric test and protection device is set for stopping fire of cables at the supply end.

Description

technical field [0001] The invention relates to a method for supplying power by using a mixed metal wire and optical fiber cable. The method is used for transmitting electric energy and optical signals, especially for transmitting cable fire signals, and can prevent cable fires from occurring through photoelectric control. technical background [0002] In the prior art, although flame-retardant cables can be used to prevent cable fires, they often fail to achieve their purpose in practical applications. Some power supply protection can not protect the cable from fire. It is not uncommon for major fires to occur when cables catch fire in actual production and life, especially if cables catch fire in underground coal mines, it is easy to cause gas and coal dust explosions. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, adopt a hybrid cable powered by metal wires and optical fibers, and use this cable...
