[0002] As one of the important equipment of the switch cabinet, the trolley-type high-voltage circuit breaker will be activated when a fault occurs. During the long-term operation of the switch, the switch often refuses to open, refuses to close, and trips secretly, causing the remote backup protection device to be activated, resulting in over-tripping and expanding the power outage area.

[0003] There are four common reasons for the electrical failure of the trolley-type high-voltage circuit breaker to refuse to open or close:

[0004] (1) Fault in the opening and closing coil of the trolley-type high-voltage circuit breaker;

[0005] (2) The trip coil of the trolley-type high-voltage circuit breaker loses voltage or is undervoltage;

[0006] (3) Trolley-type high-voltage circuit breakers do not store energy;

[0047] Example:

[0048] This embodiment provides a relay protection overall adjustment switch action monitoring and analysis device, which is specifically described as follows.

[0049] The relay protection overall debugging switch action monitoring and analysis device consists of 4-way current detection modules, 4-way voltage detection modules, a central processor, a 4G communication module and an online control platform. Figure 1 shown.

[0050] (I) MCU hardware circuit design

[0051] With the single-chip microcomputer as the core, the 8-way sensor divides the signal through the AD voltage divider module and connects it to the corresponding AD acquisition pin of the single-chip microcomputer. The AD function module inside the single-chip microcomputer performs AD conversion and data acquisition, and saves the collected data to the data storage module, and displays the data through output. In addition, the single-chip microcomputer monitors the touch action of the touch screen in real time, switches and controls the display interface, and inputs parameters to realize the human-computer interaction function. AD conversion converts the 8-way voltage signal into a digital signal, and then processes and stores all the collected signals.

[0052] The hardware structure can be roughly divided into pressure conversion module, AD conversion module, data processing and storage module and touch screen display module. The overall circuit is centered on the single-chip microcomputer and mainly includes power module, single-chip microcomputer system module, data storage module, AD voltage divider module, input module and USB module. The overall framework structure is as follows Figure 2 shown.

[0053] (II) Data Acquisition Chip

[0054] The data acquisition chip is an important component for realizing the collection and analysis of the relay protection overall debugging switch action monitoring and analysis device. It is mainly composed of three modules: a high-speed and high-precision digital-to-analog converter, a precision micro isolation amplifier and a processor.

[0055] (1) High-speed and high-precision digital-to-analog converter

[0056] The AD7606B is a 16-bit, synchronous sampling, analog-to-digital conversion data acquisition system (DAS) with 8 acquisition channels. It can quickly collect three-phase time, insulation resistance, loop resistance, current and voltage data of the circuit breaker. Each channel has built-in analog input clamp protection, programmable gain amplifier (PGA), low-pass filter and 16-bit successive approximation register (SAR) analog-to-digital converter (ADC).

[0057] AD7606B negative full-scale (NFS) error: NFS error is the difference between the first code transition and the ideal first code transition (-10V + 1 / 2LSB(-9.99984),-5V+ 1 / 2LSB(-4.99992) and -2.5V+ 1 / 2LSB(-2.49996)). This can greatly improve the accuracy of data collection.

[0058] AD7606B Signal-to-Noise and Distortion Ratio (SINAD): SINAD is the signal-to-noise and distortion ratio measured at the ADC output. The signal here is the RMS value of the fundamental amplitude. The noise is the sum of all non-fundamental signals below half the sampling frequency (fS / 2, excluding DC signals). In the digitization process, the size of this ratio depends on the number of quantization levels. The more quantization levels, the smaller the quantization noise. For an ideal N-bit converter with a sine wave input, the theoretical value of the signal-to-noise ratio is calculated as:

[0059] SINAD=(6.02N+1.76)(dB)

[0060] Therefore, for a 16-bit converter, the SINAD is 98dB, which reduces the interference of signal noise on the acquisition during the acquisition process and improves data accuracy.

[0061] Power Supply Rejection Ratio (PSRR) of the AD7606B: Power supply variations affect the full-scale conversion of the converter, but do not affect its linearity. Power supply rejection (PSR) is the maximum full-scale conversion point change caused by the power supply voltage deviating from the nominal value. PSRR is defined as the ratio of a 100mVp-p sine wave applied to the AVCC power supply at the ADC frequency fS to the ADC output power at this frequency fS. PSRR (dB) = 20log (0.1 / PfS), where: PfS is equal to the power coupled to the AVCC power supply at frequency fS.

[0062] The AD7606B also has built-in flexible digital filters, a low drift 2.5V precision reference and reference buffer (for driving the ADC), and flexible parallel and serial interfaces. The AD7606B operates from a single 5V supply and supports ±10V, ±5V, and ±2.5V true bipolar input ranges when all channels are sampled at a throughput rate of 800kSPS. The input clamp protection can withstand voltages up to ±21V. The AD7606B has a 5MΩ analog input impedance, and the bipolar zero code is less than 20LSB when the input signal is disconnected and pulled to ground through a 10kΩ external resistor. Single-supply operation, on-chip filtering, and high input impedance eliminate the need for an external driver op amp (requires a bipolar power supply) when used in applications with lower throughput rates. For applications with lower throughput rates, the AD7606B's flexible digital filters can be used to improve noise performance, allowing for fast acquisition of multiple circuit breaker data for digital-to-analog conversion.

[0063] (2) Precision Micro Isolation Amplifier

[0064] The ACPL-790 precision miniature isolation amplifier is designed for isolated current sensing and voltage sensing. In a typical application, current flows through an external resistor and the resulting analog voltage drop is detected by the isolation amplifier. A differential output voltage proportional to the current is generated on the other side of the optical isolation barrier. This differential voltage has noise rejection, low offset, high gain accuracy and stability.

[0065] (3) Processor

[0066] The model adopted is F1C100S, the processor is based on arm9cpu architecture, with high functional integration, high speed and large storage.

[0067] Multi-channel acquisition of current, voltage and resistance. According to the DC power supply for opening and closing, energy storage and closing lockout required for the electric opening and closing of high-voltage circuit breakers, multi-channel acquisition can be used to simultaneously acquire the opening and closing resistance, energy storage and closing lockout current and voltage of high-voltage circuit breakers during the operation of high-voltage circuit breakers.

[0068] (III) Bus control

[0069] The bus selection control is completed by two groups of 74F245 three-state bus transceivers. One end of the two bus transceivers is connected to the address bus and data bus of the static RAM, and the other end is connected to the high-speed and high-precision digital-to-analog converter bus and the external bus composed of the address output of the address generator and the data output of the A / D converter. During the circuit breaker data collection period, the external bus is selected, and the A / D converter directly writes the collected circuit breaker data into the static RAM for storage. When the circuit breaker data collection is completed, the high-speed and high-precision digital-to-analog converter system bus is selected, and the high-speed and high-precision digital-to-analog converter performs calculations on the data in the static RAM.

[0070] (IV) Data Collection

[0071] When the system is powered on or performing internal data processing, the D flip-flop should be cleared to put the data acquisition circuit in a disabled state. When the high-speed and high-precision digital-to-analog converter is initialized or ready, first write the starting address of the data block to the address generator, set the bus switching control line, and hand over control of the RAM to the acquisition circuit. Set the D flip-flop to start circuit breaker data acquisition, and then wait for the end of data acquisition. During the data acquisition process, the microcontroller can also forcibly interrupt data acquisition by clearing the D flip-flop. When the collected data fills up the static RAM, the address generator sends an overflow pulse to clear the D flip-flop. The output of the D flip-flop stops the address generator and the A / D converter through the AND gate, and at the same time notifies the high-speed and high-precision digital-to-analog converter through the end flag, and converts and transmits the detection data. Figure 3 shown.

[0072] (1) Current sampling resistor

[0073] The precision sampling resistor is designed, and the current passing through it is collected by timer. The voltage value at both ends is collected once every 10uS by high-speed analog-to-digital converter, and then averaged and filtered by accumulating the average value 10 times. This reduces the interference error of ripple noise.

[0074] (2) Voltage sampling

[0075] The resistor voltage division method is used to make the voltage range within the signal input range, and then the voltage signal is followed by the operational amplifier to increase the input impedance. The influence of the sampling resistor on the voltage is reduced. The voltage acquisition is also carried out by timing acquisition and cumulative averaging.

[0076] (3) Opening and closing time

[0077] The triggering, acquisition and end are started by the CPU internal timer. The triggering time is synchronized with the acquisition.

[0078] (V) Data transmission

[0079] The collected data is transferred to the address generator, A / D converter and the write control terminal of the static RAM. The address generator is designed to be triggered by the rising edge, and the A / D converter MAX1426 also starts conversion on the rising edge. Therefore, when the rising edge arrives, the address generator adds 1 to the address to form a new address. At the same time, the A / D converter performs analog-to-digital conversion. When the falling edge of the clock arrives, the output collected data of the A / D converter has been stably placed on the data bus, so that the data can be saved.

[0080] (VI) Detection mode

[0081] (1) When the trolley-type high-voltage circuit breaker is closed or reclosed remotely, when the closing coil is detected to have current, the closing coil and energy storage motor current and voltage acquisition module is started to collect the closing coil and energy storage motor current and voltage at high speed, and synchronously generate the closing coil and energy storage motor current and voltage curves. Figure 4 and Figure 5 shown.

[0082] (2) When the trolley-type high-voltage circuit breaker is remotely opened or fault-opened, when the opening coil is detected to have current, the current and voltage acquisition module of the opening coil and the closing lock coil is started to collect the current and voltage of the opening coil and the closing lock coil at high speed, and synchronously generate the current and voltage curves of the opening coil and the closing lock coil. Figure 6 and Figure 7 shown.

[0083] (3) Display the voltage and current curve of the opening and closing circuit, the voltage and current curve of the energy storage circuit, and the voltage and current curve of the locking circuit on the same coordinate axis to form a dynamic curve of the high-voltage circuit breaker action.

[0084] (VII) Intelligent judgment

[0085] (1) Detection of the dynamic resistance of the opening coil, the power-on time of the opening coil, the operating current of the opening coil, and the operating voltage of the opening coil.

[0086] By testing the opening coil action current, voltage, and dynamic resistance, the distortion and mutation of the current and voltage curves during the opening coil action process are analyzed, and there are obvious changes compared with the initial values, and the insulation performance degradation state and electrical performance degradation state of the opening coil can be accurately judged. By testing the opening coil power-on time △Tf=Tf2-Tf1, and there are obvious changes compared with the initial value, the switching reliability of the auxiliary switch can be accurately judged.

[0087] (2) Detection of closing coil dynamic resistance, closing coil power-on time, closing coil operating current, and closing coil operating voltage.

Compared with the initial values, there are obvious changes, and the insulation performance degradation state of the closing coil and the electrical performance degradation state of the closing coil are accurately judged. By detecting the closing coil power-on time △Th=Th2-Th1, and comparing with the initial value, there are obvious changes, and the switching reliability of the auxiliary switch can be accurately judged.

[0089] (3) Detection of the energy storage motor’s operating voltage, current and time of operation.

[0090] By detecting the energy storage motor's operating current and voltage, the distortion and mutation of the current and voltage curves during the energy storage motor's operating process are analyzed. Compared with the initial values, there are obvious changes, and the insulation performance degradation state and electrical performance degradation state of the energy storage motor can be accurately judged. By detecting the energy storage motor's power-on time △Td=Td2-Td1, and comparing it with the initial value, there are obvious changes, and the effective power of the energy storage motor and the fatigue state of the energy storage spring can be accurately judged.

[0091] (4) Detection of closing and locking coil operating voltage and closing and locking coil operating current.

[0092] By detecting the operating current and voltage of the closing and locking coil, the distortion and mutation of the current and voltage curves during the closing and locking coil operation process are analyzed. Compared with the initial values, there are obvious changes, and the degradation state of the closing and locking coil insulation performance and the degradation state of the closing and locking coil electrical performance can be accurately judged.

[0093] The relay protection overall debugging switch action monitoring and analysis device can online control the current and voltage fluctuation curves during the operation of the trolley-type high-voltage circuit breaker. Through intelligent analysis of the current and voltage fluctuation curves during the operation of the trolley-type high-voltage circuit breaker, the fault point of the trolley-type high-voltage circuit breaker refusal to open or close can be quickly and accurately found, thereby improving the operating reliability and action correctness of the trolley-type high-voltage circuit breaker and ensuring the healthy operation of the safe power grid.
