Product information
SSOC20 intelligent measurement and display unit for switchgear.
The SSOC20 has a dynamic simulation diagram, digital display of temperature and humidity inside the cabinet (liquid crystal or digital) and programmable control, live display and locking, intelligent voice error prevention prompt function. It can also optionally be configured with RS485 digital communication, human body induction function, high-voltage live self-inspection function, and nuclear phase/electrical inspection detection port. According to the user's control requirements, corresponding operation conversion switches (including energy storage switch, remote/local conversion switch, opening/closing conversion switch) can be installed on the device. After the temperature and humidity control is digitized, users can set the upper and lower limits of heating/dehumidification output and the upper and lower limits of overheating exhaust according to their needs, making the temperature and humidity control more effective and targeted.
Function annotation
Dynamic simulation diagram.
According to the user's primary system diagram and voltage level (35KV is yellow, 10KV is maroon, and 6KV is blue), a mask is made. The break points (such as circuit breakers, handcart positions, grounding switches, energy storage, etc.) are represented by dynamic indication modules to form real-time dynamic indications, thus bringing operators more intuitive, richer and more accurate status information. The indication contents are as follows:
■ Circuit breaker opening indication. ■ Circuit breaker closing indication. ■ Indication of handcart working position.
■ Indication of handcart test position. ■ Energy storage indication. ■ Grounding indication.
Anti-misoperation voice prompt:
■ When the circuit breaker is not in the working position or test position, the working and test position indicator lights flash simultaneously. If the circuit breaker is in the closed state at this time (the red vertical simulation bar is illuminated), there will be a voice prompt of "Please open the circuit breaker" until the operator performs the opening operation. This prevents the operator from mistakenly forcibly pushing the handcart to the working position when the circuit breaker is in the closed state.
■ When the circuit breaker is not in the working position or test position (the working and test position indicator lights flash simultaneously) or when it is in the working position (the working position indicator light is illuminated), if the grounding switch is mistakenly forcibly closed and causes the grounding closing indicator light to be on, there will be a voice prompt of "Please open the grounding switch".
■ When the above two misoperations occur simultaneously, there will be a voice prompt of "Please open the circuit breaker. Please open the grounding switch".
Live display and locking:
■ Live display LED excitation voltage (KV): Rated phase voltage × (0.15 to 0.65).
■ Forced locking activation voltage (KV): Below rated phase voltage × 0.65.
■ When any one phase of the three phases is live, the relay of the locking control part is disconnected, and the electromagnetic lock is prohibited from operating. When all three phases are not live at the same time, the locking release light is on, the relay is closed, and the electromagnetic lock is allowed to operate.
Note: Forced locking control power supply: AC or DC 220V, which can ensure the reliable operation of the locking part. During operation, if the control power supply disappears, the locking contact will not misoperate, and the locked equipment will still be reliably locked.
Temperature and humidity digital display and control:
It can be equipped with 1 to 2 channels of temperature and humidity sensors and output contacts, and can display the temperature and humidity values on site. Users can set the upper and lower limits of heating/dehumidification output according to their needs. When the ambient temperature is ≥40°C, heating is unconditionally stopped to prevent overheating damage.
Operation functions/operation switches:
■ Remote/local operation. ■ Opening/closing operation. ■ Energy storage operation. ■ Lighting operation.
RS485 communication:
Digital communication uses RS485 communication interface and MODBUS communication protocol. Through the RS485 interface, multiple sets of intelligent operation and display devices for switchgear can be networked for communication.
Human body induction probe:
When someone stands in front of the cabinet and stays, the device automatically starts the backlight of the LCD screen. When power is on, there is a voice prompt. After the operator leaves, it automatically stops.
High-voltage live self-inspection function:
The high-voltage live self-inspection button is a self-resetting button (without lock). When the main unit is live but the three phases are not live, press the self-inspection switch. The three-phase high-voltage indicator lights are simultaneously powered by the internal power supply and lit up. The unlocked state is converted to the locked state (the unlock light goes out), and the electromagnetic locking output relay is disconnected.
Electrical inspection/nuclear phase detection port:
The control device can provide a set of (three-phase) electrical inspection/nuclear phase external detection ports, which need to be used in conjunction with an electrical inspection/nuclear phase detector (purchased separately). Insert the electrical inspection/nuclear phase detector into a certain phase sequence port and grounding port of the electrical inspection end. If the electrical inspection/nuclear phase detector shows a display, it means that the tested phase sequence is live. Insert the electrical inspection/nuclear phase detector into the same phase sequence port of the electrical inspection/nuclear phase of two control devices. If the electrical inspection/nuclear phase detector does not show a display, it means that the phase sequences are the same.
