Intelligent electrical fire monitoring detector [supports function customization]

Intelligent electrical fire monitoring detector (current leakage and temperature detection)
: The electrical fire monitoring detector (hereinafter referred to as the current detector) is an independent intelligent detector. As the relay part of the signal processing of the electrical fire monitoring system, the current detector can intelligently analyze and process the signals transmitted from the current probes of the lower-level terminals through built-in circuits and software, so that the status of each current probe of the lower-level terminals can be judged ( That is, fault state, fire alarm state, normal working state), it is suitable for places with complex circuits such as factories, large warehouses, offices, commercial buildings, hotels, residences, and entertainment venues where the probability of electrical fires is greatest.

A new type of residual current electrical fire monitoring detector (hereinafter referred to as the monitor) is designed with reference to international advanced technology and developed according to the current situation of domestic power distribution network. This monitor is suitable for AC/DC power distribution circuits with rated working voltage and rated working current. It is widely used in unit power supply systems of high-rise buildings and residential buildings in high-risk warehouses and power systems in gas stations, hotels, and densely populated buildings. , can effectively ensure the safety of electricity and prevent the occurrence of electrical fires.
: < 2. Product Structure and Principle
The monitor is composed of a shell, buttons, display screen input and output interface combined with a high-performance microprocessor chip.
The display screen and buttons play the role of human-machine dialogue, and the LCD display customized according to the focus of the display is more concise and clear. Various sensors and input and output interfaces perform a series of complex actions such as signal acquisition, processing and control. All kinds of real-time information and control signals of this product can be read and controlled on the host computer through R communication.
The basic working principle of the monitor is: obtain the current power grid information through the residual current transformer and temperature sensor, submit it to the microprocessor for calculation, identification and judgment, verify it and send it to the control circuit, and at the same time send the information to the host computer and display screen for operator observation.

Please read these instructions carefully before installation.
, installation
Install the monitor on the panel of the distribution box or on the guide rail inside the box, and fix the residual current transformer at a suitable position in the box, so that all outlet terminals of the molded case circuit breaker are connected from the mutual inductance passed through the vessel.
: <, Wiring
Monitor power lines, control signal lines, and tripper output lines can all be RR or higher specification twisted pairs.
: < The monitor should draw power from the incoming end of the molded case circuit breaker. Take any phase B and connect it to the power port (port No.), and connect the connected phase to the power port (port no.).
The transformer should be connected to the corresponding transformer input port according to the monitoring loop, without polarity distinction.
: < Trip unit output: Corresponding to the monitoring circuit, connect any phase B of the outlet terminal of the molded case circuit breaker to any one of the tripping output terminals of the monitor, and lead the other end of the tripping output to the shunt. The tripping coil is connected to the tripping coil of the tripping device, and one end of the tripping coil is connected to the neutral line outlet of the molded case circuit breaker to realize tripping control. (Note: All tripping outputs of this product are contact passive outputs, which only provide breaking function. To achieve shunt tripping, power must be introduced) Alarm output: The alarm output of this monitor is a relay contact passive output, with normal Open, public and normally closed points are connected according to the requirements of external alarm.
Fire linkage input: Get the linkage signal from the fire host, and connect the positive pole to the monitor number port (with positive and negative conversion inside, so there is no need to distinguish between positive and negative input for actual access) to achieve circuit breakage through the monitor Remote strong cut control of the device switch.
R communication: Connect the monitor’s port number to the bus number line, and connect the number port to the bus B number line. All monitors do not have matching resistors inside, so when the number is large and the distance is long, The end of the communication line should be externally connected with an ohmic matching resistor between the bus line and the B line (or directly connect the resistor to the communication matching port). If a shielded communication line is used, only one end of the shielded line needs to be grounded.
, test
The wiring of the detector should be confirmed before powering on the detector, and the fixed connection part should be kept firm. After powering on, attention should be paid to checking whether the tripping action of the detector's audible and visual alarm display device is normal. It can be put into use only after it is correct.

When all setting and viewing operations are completed, press the Cancel key twice, and the system will exit the menu and return to the normal operation monitoring interface.
The silence key is used to cancel the audible and visual alarm status and restore the trip output relay.
The self-test button is used to re-test the connection status of the transformer and the action status of the alarm trip output. The self-test will cause the tripper to operate. Be sure to pay attention to the load connection of the circuit breaker when using it.
Remarks: This monitor uses the R communication method, and the communication address setting cannot exceed
When setting the password, the numerical range cannot exceed
: < Fifteen Precautions
It is strictly prohibited to disassemble this device without permission monitor, otherwise our company will have nothing to do with any consequences arising therefrom.
The use and installation of this monitor must be operated by professionals. Be sure to read this instruction carefully before operation.
After the circuit breaker is tripped by the detector, the cause must be investigated and the closing operation can be performed only after confirming and eliminating it
Be sure to distinguish between the ground wire and the neutral wire. In the monitoring circuit, the neutral wire must pass through the transformer.
When selecting a detector, attention should be paid to whether the technical parameters on the detector are consistent with the requirements of the actual application.
Periodically check to remove dust on the surface of the heat dissipation holes of the casing, pay attention to the connection status of the terminals, and maintain reliable insulation.
During use, storage and transportation, it must not be subject to rain erosion, sunlight exposure, or violent impact, so as not to damage the stability and accuracy of the monitor.
The alarm setting value of the monitor should take into account the normal leakage value of the power distribution system and electrical equipment.
