Overview; The KXH127 explosion-proof and intrinsically safe sound and light signal device developed by our company is suitable for signal communication in explosive gas environments underground. Convenient production, labor-saving, increased safety and reliability of underground operations, and improved economic benefits. It has broad promotion prospects and practical value. This device is much more advanced than the original combination bell signal and the sound and light signals from other domestic manufacturers. This product has certain * characteristics:
It is lightweight and integrates functions such as a button, explosion-proof light, explosion-proof bell, and three-way junction box. The original explosion-proof lights have been replaced by high brightness light-emitting diodes, which are eye-catching, intuitive, and *; The original electric bell was replaced by the current high-frequency waterproof speaker, with high sound frequency and long transmission distance. The dot button is replaced by the dot button on the local machine. The explosion-proof chamber of this device has an independent wiring chamber, with four external outlets left, without the need for a three-way connection. The overall structure is relatively simple and reasonable< br />1、 Signal sending: Press the explosion-proof signal button on this station to send signals (dots) to this station and all connected stations< br />2、 Signal reception: Each connected device can receive signals from any device and emit them through speakers; 85dB audio signal and visible light signal within 20 meters emitted through light-emitting diodes< br />3、 Single function intercom: This device achieves power carrier intercom function by connecting each unit through a power line without changing the power supply and wiring method of the existing coal mine explosion-proof signal device. 2、 Structural characteristics: Compared with other similar products, this product has the following three main characteristics: (1) Simple wiring, reduced explosion points, and easy maintenance& nbsp;     (2) This product uses frequency modulation power carrier for communication, with strong anti-interference ability and clear transmission distance< (3) The electronic part of the product's movement is encapsulated in epoxy, which is moisture-proof, vibration resistant, has a long service life, and requires minimal maintenance. 3、 Main technical parameters& nbsp; Number of online units; Rated working voltage; Rated working current; Signal call distance; External dimensions (mm); Weight (kg)& 10 units; AC127V AC180mA 2000m; 245× 150× 110 & lt;10  4、 Under normal working conditions, the air pressure should not be less than 80KPa& nbsp;                                        (2) The temperature of the surrounding medium shall not exceed+40 ℃ and shall not be lower than -20 ℃< (3) The relative humidity of the surrounding air shall not exceed 95% (20 ℃± 5 ℃)< (4) There are no gases or vapors capable of corroding metals and damaging insulation, but it is allowed to work in environments containing explosive gases and coal dust containing methane< (5) Places without strong vibrations and bumps& nbsp;                              (6) A place that can prevent liquid from entering< The rated voltage of the power supply for this device is 127V, with a fluctuation range of -20% to+15%< br />
