Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power transformation maintenance, and particularly relates to a modular cable partition wall system for a power distribution room and a monitoring and control method thereof. BACKGROUND

[0002] Generally, a partition wall structure is used when high-voltage cables, low-voltage cables and control cables of a power transformation station enter or exit a house. When the indoor and outdoor environments of a power distribution device room differ in temperature and humidity or when it rains heavily, a well-sealed cable partition wall can effectively prevent moisture or water from entering the power distribution room through cable holes, so as to avoid excessive humidity or water accumulation in the cable trench, thereby causing water vapor condensation on the surface of the insulation material in the switch cabinet equipment, reducing the insulation strength, causing partial discharge and damaging the equipment. In addition, the cable partition wall should also have the functions of fire prevention and small animal prevention, so as to ensure the safe and reliable operation of the power distribution room equipment.

[0003] The existing cable partition wall structure is relatively simple, and has poor fireproof, small animal prevention and waterproof performance. Generally, a conventional brick and concrete wall and a pre-buried steel pipe are used for construction, and measures such as fireproof materials or cement plugging, wall surface brushing and coating of waterproof materials are used for repairing and processing the cable holes. When the cable is expanded and laid later, the cable partition wall needs to be damaged, and it is basically impossible to repair it completely. The cables passing through the wall in different projects are complex and disordered in structure, and there is currently no effective measure for repair. Due to the difficulty in repairing the wall, the easy falling off of fireproof materials and other reasons, it is easy to cause the entry of moisture, water, small animals and fire into the power distribution room, resulting in condensation discharge of high-voltage equipment, short circuit caused by small animals and fire spread, and other serious consequences.

[0004] The existing cable partition wall generally does not have state monitoring and control measures. Manual inspection cannot timely observe the plugging condition and moisture-proof performance change of the cable partition wall, and cannot timely find the wall damage, water leakage and other conditions. When the cable partition wall is damaged, only the humidity sensor data can be used for judgment, the state monitoring method is relatively passive, real-time monitoring of the health condition of the cable partition wall cannot be realized, and necessary emergency control measures cannot be taken for the damaged cable partition wall environment. SUMMARY

[0057] As shown in the control flowchart, the application designs a set of modular cable partition wall system monitoring control method for the power distribution room, and there are two working modes, namely an automatic mode and a manual mode. Figure 9 As shown in the control flowchart, the application designs a set of modular cable partition wall system monitoring control method for the power distribution room, and there are two working modes, namely an automatic mode and a manual mode.

[0058] 2.1 Automatic mode:

[0059] In the automatic mode, the camera module (4), the differential pressure monitoring module (5), the moisture monitoring module (6) and the water immersion monitoring module (7) collect real-time images, inner-outer pressure difference, wall moisture content, water accumulation degree and other data, and transmit them to the on-site control cabinet for processing.

[0060] 2.2 Manual mode:

[0061] In the manual mode, the remote terminal sends start-stop commands to the electromagnetic valve drainage module (8), the fan module (9) or the dehumidification module (10) through the on-site control cabinet, so as to realize remote manual start-stop of each control module.

[0062] 3. Control logic:

[0063] The alarm threshold 1 of the differential pressure is set as ΔP o1 , the alarm threshold 2 is set as ΔP o2 The control signal of the electromagnetic valve drainage module (8) is set as A1, the control signal of the fan module (9) is set as A2, the control signal of the dehumidification module (10) is set as A3, the start threshold of the wall moisture content is set as W0, and the stop threshold is set as W C , so as to realize hysteresis control of the wall moisture content.

[0064] ΔP is defined as the inner-outer pressure difference of the cable partition wall, P n1 is the pressure value collected by the differential pressure monitoring module (5) at t n1 , and P n2 is the pressure value collected by the differential pressure monitoring module (5) at t n2 , so that:

[0065] ΔP = P n1 -P n2

[0066] Define K as the wall water content slope value, W n1 is the wall water content value measured by the moisture monitoring module (6) at time t n1 is the wall water content value measured by the moisture monitoring module (6) at time t n2 is the wall water content value measured by the moisture monitoring module (6) at time t n2 is the wall water content value measured by the moisture monitoring module (6) at time t n1 -t n2 is the sampling interval, then:

[0070] When the water accumulation detection value M is 0, and the cable partition wall inside and outside pressure difference ΔP is greater than the warning threshold 1ΔP o1 , it is judged that the cable partition wall is well sealed and has no water accumulation. When the wall water content W n is greater than the starting threshold W0, and the wall water content slope value K is greater than 0, the cable partition wall surface moisture shows a growing trend, at this time, the fan module (9) control signal A2 and the dehumidification module (10) control signal A3 are started; when the wall water content W n reaches the peak and starts to drop, when it drops to , the fan module (9) control signal A2 is closed; when the wall water content W n continues to drop to, when it drops to the stop threshold W C , the dehumidification module (10) control signal A3 is closed.

The monitoring data and alarm signals are uploaded to the remote terminal through the power distribution room network server to realize real-time online monitoring and control. In manual mode, the remote terminal sends start / stop commands to the solenoid valve drainage module (8), fan module (9), or dehumidification module (10) through the local control cabinet, so as to realize remote manual start / stop of each control module.

4. The monitoring and control method for a modular cable partition system in a power distribution room according to claim 3, characterized in that, The control logic of the local control cabinet in automatic mode is as follows: Set the differential pressure alarm threshold to 1. Alarm threshold 2 is Set the control signal of the solenoid valve drainage module (8) to A1, the control signal of the fan module (9) to A2, and the control signal of the dehumidification module (10) to A3. Set the wall moisture content activation threshold to... The stopping threshold is This enables hysteresis control of wall moisture content; definition P represents the pressure difference between the inside and outside of the cable partition wall. n1 For t n1 The differential pressure monitoring module (5) collects the pressure value inside the cable partition wall, P n2 For t n2 If the pressure value outside the cable partition wall at any given time is: Let K be the slope value of the wall's moisture content, and W... n1 For t n1 The wall moisture content value measured by the real-time moisture monitoring module (6), W n2 For t n2 The wall moisture content value measured by the real-time moisture monitoring module (6), t n1 -t n2 Let be the sampling interval, then: M is defined as the water accumulation detection value output by the water immersion monitoring module (7). When the water accumulation depth H in the cable partition wall water collection tank is greater than or equal to the set value H0, the value of M is 1, and otherwise it is 0. When the water accumulation detection value M is 1, the control signal A1 of the solenoid valve drainage module (8) is enabled, and the control signals of other modules are closed to prevent a large amount of water vapor in the cable trench from being introduced into the power distribution room. When the pressure difference between the inside and outside of the cable partition wall The pressure dropped to the differential alarm threshold 1 At that time, if the cable partition wall has poor sealing, the local control cabinet will transmit a "differential pressure warning" signal to the remote terminal; when the pressure difference between the inside and outside of the cable partition wall... Continue to decrease to the differential pressure alarm threshold 2 At this time, the cable partition wall is severely damaged. At this time, the local control cabinet transmits the "differential pressure alarm" signal to the remote terminal and shuts down the fan module (9) control signal A2 and the dehumidification module (10) control signal A3 to prevent outdoor moisture from being introduced into the power distribution room. When the water accumulation detection value M is 0, and the pressure difference between the inside and outside of the cable partition wall is 0... Greater than alarm threshold 1 At that time, it was determined that the cable partition wall was well sealed and there was no water accumulation. When the wall moisture content W n When the moisture content of the wall exceeds the starting threshold W0 and the slope value K of the wall moisture content is greater than 0, the surface moisture of the cable partition wall shows an increasing trend. At this time, the fan module (9) control signal A2 and the dehumidification module (10) control signal A3 are activated. When the wall moisture content W n After reaching its peak, it begins to decline, and when it decreases to... When the wall moisture content W is low, the fan module (9) control signal A2 is turned off; n Continue decreasing until the threshold is reached. When the dehumidification module (10) is turned off, control signal A3 is turned off; For control signal A1, when A1=1, the solenoid valve drainage module (8) starts, and when A1=0, the solenoid valve drainage module (8) stops. For control signal A2, when A2=1, the fan module (9) starts, and when A2=0, the fan module (9) stops. For control signal A3, when A3=1, the dehumidification module (10) starts, and when A3=0, the dehumidification module (10) stops. The start / stop control of each module is related to the current wall moisture content W. n Water accumulation detection value M and pressure difference between inside and outside the cable partition wall The function is represented as follows: 。
