KXH127A language flameproof and intrinsically safe sound and light signals, KXH127 combination of signal devices, KXT127 sound and light signals, KXT102 combination of sound and light signals 1. Overview KXH127A Mine explosion-proof and intrinsically safe language sound and light signals, mainly used workplace containing coal dust and explosive gases in the coal mine. Supply voltage of 127V. Speaking through the communication lines to achieve carrier. From the mine moisture and bright light-emitting diodes speaker sound and light signals. Both sides have to stop operating the device can be directly stop locking tab, find an emergency, after the failure to lift, press the reset button to restart the device. 2. Categories 2.2 type mine explosion-proof and intrinsically safe; mark as: "Exd [ib] I Mb"; 2.3 Dimensions and weight Dimensions :( L × W × H) 315mm × 220mm × 88mm; Weight: approximately 12.5Kg. 2.4 Environmental Conditions 2.4.1 The signal should be able to work under the following conditions: a) ambient temperature: 0 ℃ ~ 40 ℃; b) Humidity: ≤95% (when the ambient temperature is + 25 ℃ when); c) atmospheric pressure : 80kPa ~ 106kPa; d) for use in hazardous places explosive coal dust and methane gas, but no damage to insulation corrosive gas. 2.4.2 signal can withstand the harshest storage conditions: a) Storage temperature: -40 ℃ ~ 60 ℃; b) Vibration: 50m / s2; c) Impact: 500m / s2. 3 Structure and working principle 3.1 of the product wiring is simple, easy to maintain, easy to use; 3.2 Communication take FM carrier, anti-interference ability, transmission distance, good communication effect. 3.3 signal transmission: Press this station explosion chamber RBI Send button to send the audio signal contact (RBI) to this station and all stations online; 3.4 signal reception: Online each station can accept the one sent by any communication line carrier signal, given greater than 85dB (A) noise signal through the speaker, and issued within 20 meters visible light signal by light emitting diodes. 3.5 Simplex intercom: this means without changing existing mines flameproof signal devices and power wiring in the case, each single-station intercom station via power line carrier communication function. 3.6 Emergency stop: Pull the rope looped, so any position along the rope pull tab can drive to achieve stop. 4 Technical features 4.1 Technical Data 4.1.1 Supply voltage: AC127V 4.1.2 Intrinsically safe parameters: UO: DC 11V IO: 550mA. Operating voltage: DC10.5V, working current: 325mA. 4.2 electro-acoustic performance 4.2.1 annunciator call mode: simplex intercom; 4.2.2 RBI signaling signal: two-tone signal; 4.2.3 annunciator voice signal intensity sound level should ≥85dB (A). 4.2.4 annunciator light signal is red, clearly visible at 20m visibility in the dark. 4.2.5 action stroke: 10mm ± 2mm 4.2.6 Emergency Action Force: 80N ± 20N 4.2.7 reset force: 75N ± 15N 4.3 Basic functions 4.3.1 transmitting and receiving signals: a signal having a human transmission signal and receiving the signal functions and You can achieve simplex intercom. 4.3.2 Call and RBI Distance: annunciator call with RBI distance 2km (with another signal when used in conjunction). 4.3.3 Emergency stop function: Emergency pull ring opened with emergency stop blocking function. Caution a) use of the power supply voltage and the voltage on the nameplate to be consistent. b) at the time of use and maintenance, can not change the name, type, size and parameters of intrinsically safe circuits and intrinsically safe circuits associated with electrical components. c) maintenance, maintenance, prohibited live open! Non-damage surface explosion! d) When not in use, the line must be required to block the mouth. Product details, please call to plant from exercise. Denway Jining Mining Equipment Co., Ltd. is located in Jining City, Shandong Province, Tang Industrial Park, new and old customers call to plant inspection.
