Description

Technical Field

[0001] The invention relates to a five-defense operating system based on interconnected applications. Background Art

[0002] One of the main tasks of a substation is switching operation, and the most important part of the operation is the five-protection locking function. Since the five-protection operation key needs to be carried during the operation, it is inconvenient to operate, and sometimes the operation is delayed by forgetting to carry it. During maintenance, for convenience, the staff sometimes short-circuit the five-protection lock to open and close the maintenance equipment. In order to prevent this from happening, a five-protection operating system based on interconnected applications is proposed.

[0003] The "five defenses" of the power system refer to:

[0004] ①Prevent accidental opening and closing of circuit breakers.

[0005] ②Prevent opening and closing of the isolating switch under load.

[0006] ③Prevent hanging (closing) the grounding wire (grounding switch) when it is energized.

[0007] ④ Prevent power from being supplied with a grounding wire (grounding switch), that is, prevent the circuit breaker (isolating switch) from being closed with a grounding wire (grounding switch).

[0008] ⑤Prevent accidental entry into live intervals.

[0009] II. Necessity of the “Five Preventions”

[0010] Electrical operations in power systems require certain operating procedures. Each operating step is fixed and cannot be skipped. Therefore, in order to prevent operators, maintenance personnel and other personnel from causing unnecessary accidents due to improper operation, the concept of "five-prevention" interlocking was proposed.

[0011] The "five-prevention" interlock is a positive measure taken to prevent operators from operating accidents due to misoperation. The realization of the "five-prevention" function has become one of the important measures for power safety production. With the continuous development of the power grid and the continuous updating of technology, the anti-misoperation device has been continuously improved and perfected. The design principle of the anti-misoperation device is: all high-voltage electrical equipment that may cause misoperation should be equipped with an anti-misoperation device and a corresponding anti-misoperation electrical interlock circuit.

[0012] Patent CN201620342718.3 discloses a portable switch cabinet opening and closing remote control device, and its technical solution is: the input end of the closing circuit terminal hole (4) and the remote control closing relay contact (7) are connected to each other, the input end of the opening circuit terminal hole (5) and the remote control opening relay contact (8) are connected to each other, the remote control closing relay contact (7) and the remote control opening relay contact (8) are respectively connected to the remote control receiving module (6), the power switch (1), the device indicator light (9), the remote control receiving module (6), and the receiving antenna (2) are connected in sequence, and the output end of the common terminal hole (3) is connected to the negative end of the five-protection locking of the switch cabinet.

[0013] CN200920172483.8 Intelligent anti-misoperation system for primary equipment in substations, which installs photoelectric switches and single-hole and double-hole resin isolation baffles at the most direct parts of switches, disconnectors, and grounding switches (grounding wires) on the site of substations (including power plant substations); with the rotation (movement) of the equipment, the infrared light is turned on and off, the positioning equipment, and each photoelectric switch is turned on and off to give "information" to the unit interval PLC. The PLC intelligent logic judges the equipment status inside the unit interval and between the bypass and bus-connected unit intervals. For equipment that complies with the power operation regulations and needs to be switched, it independently transmits the "operation" power supply and "electromagnetic lock" power supply required for switching operation, allowing switching operation. Each PLC information is uploaded and fully cooperates with the current "two tickets" (work ticket, operation ticket) system of the power system. The operation mode in the "two tickets" system is automatically detected and confirmed to prevent misoperation from the source; misoperation is prohibited in the links of opening, filling, checking tickets and on-site operation.

[0014] CN201520670286.4 A substation switch cabinet switching operation training system based on Zigbee. The utility model relates to a substation switch cabinet switching operation training system based on Zigbee, the system comprising a plurality of switch cabinets from which the mechanical five-protection locks have been removed; each switch cabinet is provided with a switch position detection device, an I / O module and a Zigbee communication module, the switch position detection device in each switch cabinet is connected to the I / O module, and the I / O module is connected to the Zigbee communication module; each Zigbee communication module is wirelessly networked through a coordinator, and the coordinator is connected to a host computer via a 485 bus.

[0015] Using this system, trainees can conduct multiple individual exercises, and can also simulate substation switch units for operation exercises through Zigbee wireless networking. During the operation exercises, the operation information collected by the host computer can monitor the trainees' operation process in real time, record the operation process, and point out the trainees' incorrect operations, which can effectively improve the training effect.

[0016] However, according to past operating experience, there have been many cases of high-voltage short circuits and discharges when the switch cabinet circuit breakers were opened and closed to stop power supply. With the development of power system automation, substation equipment has basically achieved remote operation. In order to ensure the personal safety of employees, it is required to prohibit the opening and closing operations of local power outages on 35 and 10 kV switch cabinets. When the switch cabinet circuit breaker needs to be opened and closed and the communication with the protection and measurement and control devices is interrupted, remote operation can no longer be achieved.

[0017] In this case, the operation and maintenance personnel are generally required to report to the leader and then perform on-site operations. This method has a very high risk factor and is generally not used unless there is an emergency. Another method is to wait for protection professionals to arrive at the site, lead the positive electricity on the switch cabinet terminal block and the secondary wires for opening and closing to the outdoors, and perform short-circuit operations outdoors. This method has a greater risk of short circuits during wiring and lead-in, which can easily cause accidents. In addition, the use of terminal block power supply operations bypasses the five-protection locks, which can easily cause misoperation accidents.

[0018] Therefore, how to make the opening and closing operations of 35 and 10 kV switchgear convenient and simple when communication is interrupted, and avoid various accidents and reduce risks is an issue that we urgently need to solve. Summary of the invention

[0111] An isolation capacitor 5 is provided between the primary positive input terminal 3 and the primary ground loop 4 .

[0112] Example 3

[0113] Same as Example 2, except that

[0114] A primary reverse-connected diode 19 connected in parallel with the coil 18 of the intermediate relay K1 is provided between the primary light-emitting diode 16 and the collector of the primary control transistor 10 .

[0115] The remote control terminal 7 has an optical signal receiving module 17 for collecting the optical signal of the primary light emitting diode 16 to detect the on-off of the circuit.

[0116] The secondary circuit includes a secondary power supply 20;

[0117] The secondary power supply 20 inputs current through the secondary interlock control module 21;

[0118] The secondary interlock control module 21 includes a secondary electric control circuit 22 and a secondary mechanical control circuit 23 connected in parallel;

[0119] A secondary normally open spring reset switch 24 and a mechanical normally closed switch 28 are connected in series on the secondary electric control circuit 22;

[0120] A secondary normally closed reset switch 25 and a mechanical normally open switch 27 are connected in series on the secondary mechanical control circuit 23 .

[0121] The secondary normally open spring reset switch 24 is linked with the secondary normally closed reset switch 25, and the mechanical normally open switch 27 is linked with the mechanical normally closed switch 28;

[0122] The mechanical normally open switch 27 and the mechanical normally closed switch 28 are reset by a spring and a rotating mechanical insulating eccentric wheel 26 is arranged on one side thereof. The mechanical insulating eccentric wheel 26 is used to rotate and press down the mechanical normally open switch 27 to close and / or the mechanical normally closed switch 28 to open;

[0123] The secondary normally open spring reset switch 24 and the secondary normally closed reset switch 25 are reset by the spring and switched on and off by the coil 18 of the intermediate relay K1.

[0124] The output end of the secondary interlock control module 21 is electrically connected to a humidity normally closed switch 29 and an execution coil 32;

[0125] The humidity normally closed switch 29 is controlled to be on and off by the humidity circuit breaker coil 31 , and the humidity circuit breaker coil 31 is controlled to be on and off by the humidity controller 30 , and the humidity controller 30 uploads the humidity data to the remote control terminal 7 .

[0126] The execution coil 32 controls the on and off of the execution normally open switch 33 on the execution circuit.

[0127] At present, the known "five-prevention" locks of substations include: mechanical lock, electromagnetic lock, electrical lock, and microcomputer lock. They are basically independent of each other, have their own shortcomings, and cannot achieve "eradicating misoperation".

[0128] Mechanical interlocking is a kind of interlocking that achieves the intended purpose by the constraints of mechanical structure. It is protected from misoperation due to pin falling off, deformation, or component welding fracture. Electromagnetic interlocking uses the auxiliary contacts of circuit breakers, disconnectors, equipment net doors, etc. to connect or disconnect the power supply of disconnectors and net door electromagnetic locks. Electrical interlocking uses the auxiliary contacts of circuit breakers and disconnectors to connect or disconnect the electrical operating power supply to achieve the purpose of interlocking. It is controlled by the operating power supply in the on-site control box or mechanism box (the same metal key or computer key is used on-site). When operation is required, the staff closes the "knife switch operating power supply" in the box and can go to the equipment to be operated to perform the switching operation (the operating power supply of each equipment in the interval has been delivered). Its main solution It solves the problem of preventing equipment from malfunctioning and has a certain effect on preventing misoperation. For example, if the metal lock or the microcomputer lock has been opened by mistake, it is no longer effective to prevent misoperation objectively (unless the staff finds it in time and stops the operation manually); the microcomputer lock is operated according to a pre-programmed program, which consists of a computer simulation disk, a computer key, an electric code unlocking, and a mechanical code lock. The on-site lock or the computer key opens the lock abnormally and causes misoperation; due to abnormal and damaged equipment transmission mechanism, the operated equipment cannot be correctly and reliably in place. All the "five-prevention" locks of the current substation cannot prevent such misoperation of switching, and the auxiliary contacts cannot 100% confirm the real "position change and position" of the switching operation in actual work. The above single or combined reasons have caused an equipment misoperation accident, which has not been effectively solved in my country's power system.

[0129] Through the scheme of the present invention, current is input through the power input coil 1, rectified through the rectifier bridge 2, and circuit circulation is achieved through the primary positive input terminal 3 and the primary grounding loop 4. The present invention realizes the interlocking of mechanical control and circuit control to avoid interference.

[0130] The isolation capacitor 5 starts the safety pressure maintenance function, the primary signal receiver 6 can be Bluetooth, radio frequency, infrared or other networks, the remote control terminal 7 realizes Internet of Things control, the primary signal transmitting terminal realizes contactless control, and the primary control circuit 9 acts as a receiver to output a signal to realize the conduction or cutoff of the primary control transistor 10, thereby realizing remote control of the secondary normally open spring reset switch 24 and the secondary normally closed reset switch 25.

[0131] Through the remote line diode 11, the primary current limiting resistor 12 plays a safety protection role. As a mechanical control, the primary manual switch 13 is turned on and off to trigger the triode, the manual line diode 14, and the primary safety capacitor 15 realize the protection effect. Through the on and off of the primary light-emitting diode 16, the optical signal receiving module 17 realizes remote recording according to the signal, the intermediate relay K1 coil 18 realizes secondary control, the primary reverse diode 19 plays a protective role, the secondary power supply 20 inputs current, and the circuit control mode is controlled by the secondary interlocking control module 21. The secondary electrical control circuit 22, the secondary mechanical control circuit 23, the secondary normally open spring reset switch 24, the secondary normally closed reset switch 25, the mechanical insulating eccentric wheel 26, the mechanical normally open switch 27, the mechanical normally closed switch 28, and the humidity normally closed switch 29 realize the on and off of the circuit. The design is ingenious and avoids interference between controls.

[0132] The humidity controller 30 and the humidity circuit breaker coil 31 are disconnected for protection when the humidity is greater than the set threshold. The execution coil 32 and the execution normally open switch 33 realize the execution work.

[0133] As an extension of the subsequent invention ideas, the present invention also discloses the following steps:

[0134] After the simulation is completed, the operator clicks on "Transfer". After fingerprint recognition or facial information is passed, the operation instructions and sequence are sent to the corresponding device. At the same time, verification information such as fingerprint recognition or facial information is sent at the same time. Only the operator is allowed to operate the device. Otherwise, the device will not be able to recognize it.

[0135] A small LCD screen is set at the equipment operation site to remind the operation: the numbers can remind the operation sequence. For example, 1 means the equipment is waiting to be operated, 2 means the next number to be operated, 0 means the equipment is operated and can be repeated (if the operation is not in place, repeat the operation). After the next equipment is operated, the equipment can no longer be operated. At the same time, the background color is attached for prompting. Green represents the equipment to be operated, red represents the equipment to be operated later, and yellow represents the equipment that can be repeatedly operated at present.

[0136] The device is connected to the original five-protection locking device at the LCD screen, and connects the corresponding closing or opening circuit through the internal contacts. That is, during the operation, only closing or opening operations are allowed. At the same time, it avoids the exposure of the five-protection device and the maintenance personnel using illegal means to close and open the knife switch. Replace the existing physical buttons of the opening and closing handles or buttons and the exposed electric code locks.

[0137] After the five-defense host simulation is completed, the command will be sent to the device terminal. According to the simulated operation situation, the closing circuit or the opening circuit will be automatically connected. The device can only be operated after the authentication is confirmed through face or fingerprint recognition.

[0138] Technical Contribution:

[0139] The invention connects the operated equipment to the five-defense host through network interconnection, and the operator no longer needs to use the five-defense operation key. It can realize that the operator does not need to carry the five-defense operation key, and at the same time, the probability of operator misoperation can be reduced through the on-site prompter. It effectively improves the operator's operation quality and work efficiency.

[0140] At present, the technical solution of the present invention has been put into pilot production, that is, a small-scale test of the product before large-scale mass production; after the pilot production was completed, a user survey was conducted on a small scale, and the survey results showed that user satisfaction was high; now preparations have begun for the formal production and industrialization of the product (including intellectual property risk warning survey).

[0141] The present invention is fully described for a clearer disclosure, and the prior art is not listed one by one.

[0142] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents; it is obvious for those skilled in the art to combine multiple technical solutions of the present invention. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
