4.2 Drawing and Pictures
4.3 Door and Door Limit
(1) Cabinet door options: vertical hinge door, horizontal hinge door.
(2) The door limit device can limit the door position when it is open.
(3) The door limit function is automatically activated when the door is open, and should be canceled manually when the door is closed.
(4) When the door is fully opened, the largest open angle is larger than 95°. If it is horizontal hinge door, it can prevent outside water from flowing into the equipment compartment from the upper side. The bottom edge of the door limit device is higher than the hinge level, which can offer enough operating space.
(5) After 1000 times open and close operation, the door and door device will have good function and have no excessive wear and tear.
(6) At the door limit status, the door limit device can bear the static load by door opening and closing at 22m/s wind, without mechanical failure and function failure.
4.4 Ventilation and Filter
(1)At the air inlet of the vent, it is welded with 1mm thick and 16 mesh stainless steel mesh, preventing insects and rodent. At the inner side of the vent, it is 10mm thick and 30ppi dust filter. The filter mesh is folded together with the fold type support mesh, and the filter is fixed inside the aluminum frame. The whole dust filter is with modular design, easy for maintenance.
(2)It is anti-corrosion and water proof, and with the function of preventing rain from flowing into the structure for the second time. There are shutter which has 35° angle with the cabinet vertical surface. Rain water will flow along the shutter. In addition, the structure design at the vent can prevent rain for the second time.
4.5 Grounding
The cabinet include grounding copper bar, 4mm thick, with 10×M6 flare-in nuts, 2×M8 flare-in nuts, 2×M10 flare-in nuts. The grounding bar is nickel plated. The screw is made from copper bar and with passivation surface treatment.
4.6 Theft Proof Design
(1) Theft proof lock
(2) Three point lock
4.7 Appearance and Surface Treatment
Outdoor powder coat, with gray color. The coat is anti-shock, anti-aging, anti-solvent, anti-low temperature.
5.Electrical Technical Parameters
5.1 Monitoring System Diagram and Solution
Monitoring alarm
The monitoring unit conducts real time monitoring on smoke, water, door opening, LED lamp, temperature and humidity inside each compartment through various sensors. It is with alarm output, and can transmit alarm signals to Local Area Network or remote monitoring platform through RS485/RS232, Ethernet etc.
Monitoring Unit Diagram
The monitoring unit uses dual core processing. the power supply uses DC/DC module. The measuring channel, power supply, and communication interfaces are electrically isolated, so the monitoring unit has high reliability . The MCU control design has functions of self management and self correction. The monitoring unit support RS485/RS232 communication method. With the communication interfaces, it can realize many kinds of communication modes, such as point to point communication, point to multipoint communication, wireless remote communication, which can meet the need of various system networks.
5.2 Monitoring and Alarm
The monitoring unit conducts the following monitoring and alarm for the cabinet: door alarm, power failure alarm, smoke alarm, water alarm, temperature and humidity detection and alarm, shock and tilt alarm, etc.
(1)Door alarm
There are two door switches. The one near the top of the cabinet is used for control the on/off of LED lamp, and the other one detects the opening and closing of the cabinet door. When the door is open, the door switch closes, and the monitoring unit will transmit the alarm to the control center through RS485/RS232. Meanwhile, there is correlative alarm dry contact output (port AL6, AL7). It will close in abnormal situation.
(2)Power failure alarm
The port “AC220V” on the monitoring unit is for utility power detecting input. In case of utility power failure, the monitoring unit will transmit the alarm signal to the control center through RS485/RS232, and there is correlative alarm dry contact output (port AL8, AL9). It will close in abnormal situation.
(3)Smoke alarm
The port “S” on the monitoring unit is for smoke sensor detecting input. When smoke is detected, the red light on the smoke sensor turn bright, the monitoring unit will transmit the alarm to the control center, and there is correlative alarm dry contact output (port AL2, AL3). It will close in abnormal situation.
(4)Water alarm
The port “w+. w-” on the monitoring unit is for water sensor detecting input. When water is detected inside the cabinet, the monitoring unit will transmit the alarm to the control center, and there is correlative alarm dry contact output (port AL4, AL5). It will close in abnormal situation.
(5)Temperature and humidity detection and alarm
The port “5V, T1, H1, GND” on the monitoring unit is for temperature and humidity sensor of battery compartment detecting input, and port “5V, T2(or T3), H2(or H3), GND” is for temperature and humidity sensor of equipment compartment detecting input. The monitoring unit can conduct real time detecting on temperature and humidity inside the compartment. When temperature and humidity sensor send out alarm signal, the monitoring unit will transmit the alarm signal to the control center, and there is correlative alarm dry contact output (port AL0, AL1). It will close in abnormal situation.
