Nanjing Nanrui Jibao RCS9611CS Line Protection Measurement and Control Device

For example, if GL1 needs to act on outlet trip relay 1, then cross handle 1 in the column where GL1 is located and in the row where CK1 is located.

If I01 and I02 also need to act on the outlet trip relay 1, then cross handle the column where I01 and I02 are located and the row where CK1 is located

Thus, in line CK1, a 16 bit binary bit string can be obtained:

CK1=0000000011000001

If a certain set of exports is not used, such as CK3, it can be completely rounded to 0, that is: 0000000000000000.

Enter the above binary bit strings for CK1, CK2, CK3, and CK4 in the protection setting menu to complete the jump

Setting of gate mode.

2.13 Device self-test

When the device detects a hardware malfunction, it sends a device lockout signal and locks the device (BSJ relay returns).

Hardware failures include: setting error, RAM failure, ROM failure, power failure, outlet circuit failure, CPLD failure.

2.14 Device operation alarm

When the device detects the following conditions, it sends an abnormal operation signal (BJJ relay action):

TWJ abnormality, line voltage alarm, frequency abnormality, PT disconnection, control circuit disconnection, grounding alarm, overload

Alarm, zero sequence segment III alarm, spring not storing energy, CT disconnection, overvoltage alarm, zero sequence overvoltage alarm.

2.15 Remote control, telemetry, and remote signaling functions

There are three main types of remote control functions: normal remote control tripping, normal remote control closing, and grounding line selection remote control tripping and closing. standard

Configure only one set of remote control output contacts (fixed corresponding to this switch); Two additional remote controls can be provided as an optional option

Refer to Sections 5.4, 5.1, and 5.2.

Remote measurement includes Iam, Icm, I0, UA, UB, UC, UAB, UBC, UCA, U0, F, P, Q, COS ф

14 analog quantities. The active and reactive energy are calculated through integration, and all of these quantities are calculated in real-time locally,

Real time accumulation. The current accuracy reaches 0.2 level, and the rest of the accuracy reaches 0.5 level.

The remote signaling volume mainly includes 16 custom remote signaling inputs and event sequence records (SOE). Remote signaling resolution is less than

1ms。

2.16 Time synchronization function

The device has software timing and hardware timing functions. Hardware timing is either second pulse timing or IRIG-B code timing,

Automatic device recognition. The time interface adopts an average 485 differential level, corresponding to terminals 207-209.

When the device detects a hardware timing signal, a "·" will be displayed in the upper right corner of the LCD main interface.

3.3.1 Analog Input

The external current and voltage input are isolated and transformed by an isolation transformer, and then input to the analog-to-digital converter through a low-pass filter,

After sampling and digital processing, the CPU forms various protective relays.

IA, IB, and IC are three-phase current inputs for protection purposes.

I0 is the zero sequence current input. It can be used for zero sequence overcurrent protection (alarm or trip), as well as for small current grounding

Used for route selection. When zero sequence current is used for small current grounding line selection, it is required to input from a dedicated zero sequence current transformer.

Iam and Icm are measurement currents that need to be input from a dedicated measurement CT to ensure sufficient accuracy in remote measurement.

UA, UB, and UC are bus voltages, which are shared for protection and measurement in this device. They are measured together with Iam and Icm

Calculate the P, Q, COS ф, kWh, and kVarh of the cost line. If there is no corresponding bus PT or the power used by this device

If voltage is not involved, UA, UB, and UC can be disconnected. To prevent the device from sending PT disconnection signals, simply adjust the protection settings

The control word 'PT disconnection detection input' exits.

UX is the line voltage, which is used for detecting no voltage in the reclosing circuit and detecting synchronization. It can be 100V or 57.7V,

Just need to be consistent with the "rated secondary value of line PT" in the system settings. If the reclosing is not activated or the reclosing is not adopted

The inspection method, UX can be disconnected.

This device produces 3U0 and is used for zero sequence voltage alarm judgment and zero sequence voltage measurement.
