[0060] The present invention will be further described below in conjunction with the embodiments and drawings:

[0061] Example 1

[0062] As described in the background technology, GIS equipment is composed of multiple high-voltage switch elements. Usually, a control cabinet is set up in the GIS according to the interval, and the operation, control and monitoring circuits are configured one-to-one with the high-voltage switch elements (mechanisms) in the cabinet to realize point-to-point control between different devices. The switch elements of GIS equipment refer to the disconnectors, grounding switches, and fast grounding switches that constitute the GIS equipment. At present, the traditional GIS secondary circuit mainly uses electrical components with single functions. In order to complete complex functions, a large number of components of various types are required, and thousands of wires are used to connect these components; the control circuit of the conventional GIS switch element is a one-to-one correspondence mode, and each switch element is equipped with a relatively independent contactor and operating switch, that is, the GIS control circuit is composed of multiple groups of contactors and operating switches; the control circuits with the same function are repeatedly set, and the components are also repeatedly set. The more components, the lower the overall reliability will be, and the more complicated the daily maintenance will be. According to incomplete statistics, the failure of the control circuit accounts for 85% of the failure rate of the disconnector. In addition, the standardization degree of the existing switch element control circuit is high, the function is relatively fixed, and the engineering changes are relatively complex. It is even more difficult for the current standardized design and manufacturing of switch elements. Engineering changes often result in hard-wired changes, making implementation more difficult.

[0063] Traditional control methods, such as Figure 1 As shown, first Figure 1 The symbols are explained as follows: CX represents a closing contactor; TX represents an opening contactor; 3-X1 represents an operating switch; SP1 represents a closing position confirmation contact; SP2 represents an opening position confirmation contact; and M represents a drive motor.

[0064] When the GIS switch element 2 is closed, it is necessary to operate 3-X2 in the control cabinet to close the operation, connect the closing circuit of the GIS switch element 2, energize and excite the CX contactor in the mechanism box, complete the switching of the contactor contacts, connect the motor circuit, and the motor M drive mechanism drives the switch element to close. When the closing operation is completed, SP1 and SP2 complete the conversion, cut off the closing circuit and connect the branch circuit at the same time to complete a closing operation. It can be seen that in the current control measures, multiple sets of control units are used, and it is an inherent one-to-one operation mode. The control circuit has problems of component redundancy and redundant lines; the reliability of operation cannot be effectively guaranteed.

[0065] In order to solve the above problems, the present embodiment provides a control method for GIS switch equipment. The control method adopts a programmable relay as the core component of the control loop, and uses its programmable function to realize the intelligence of the GIS control loop, and improves the one-to-one control mode to a centralized operation mode of first selection and then intelligent operation; reduces the redundant wiring and redundant component configuration of the traditional loop, and uses the intelligent function of the programmable relay to expand the function and engineered transformation, so as to realize the customized control and protection functions of the GIS switch elements.

[0066] This embodiment provides a control method for GIS switchgear, which uses a programmable relay as the core control component of the switch element control unit. The programmable relay is an intermediate relay with a logic programming function, which can execute the corresponding logic program through the compiled program and output it. Compared with PLC, it has low cost, strong anti-interference ability, and convenient maintenance. More specifically:

[0067] Programmable relay is an innovative universal logic control module, which fills the functional gap between traditional relays and PLC. The module itself integrates 8 basic functions such as "AND", "OR", "NOT" and 28 proprietary functions such as time timing, counter and analog processing. By adopting the internal function block programming method to replace the external wiring scheme of traditional relay switches, in a small module, users can arbitrarily call the required various function blocks to edit their own applications, thereby realizing control tasks that require many timers, relays, clocks and contactors to achieve.

[0068] This embodiment provides a control method for a GIS switch device, comprising the following steps:

[0069] The control circuit of the switch element to be operated first sends an operation application signal to the programmable relay through the switch operation application button; the programmable relay performs a logical judgment on the operation condition based on the received operation application signal, and the judgment here specifically includes whether the current operation condition meets all the following conditions, for example: voltage condition, interlocking condition and current state of the switch operating mechanism; when all the above conditions are met, it can be judged that the requirements are met; otherwise, an alarm signal is output to remind the operator to check the current state; when it is judged that the requirements are met, the programmable relay sends a contact output signal to the output contact corresponding to the switch element to be operated, so as to realize the conduction between the operating switch and the output contact, and then realize the connection of the motor control circuit corresponding to the switch element to be operated, and turn on the power supply through the corresponding operating switch opening or closing operation, so as to control the motor to drive the switch element to be operated to perform opening or closing operation.

[0070] When the opening or closing operation is completed, the closed position microswitch or the open position microswitch sends the operation completion information to the programmable relay. According to the received operation completion information, the programmable relay sends a contact reset signal to disconnect the output contact corresponding to the switch element to be operated, thereby realizing the cutting off of the motor control circuit corresponding to the switch element to be operated and the resetting of the output contact, so as to complete the next opening or closing operation.

[0071] Repeat the above steps to continue controlling the opening or closing operation process of different switching elements of the GIS switch equipment, realizing centralized intelligent control and ensuring the operational reliability of the entire control system.

[0072] Combination Figure 2 As shown, first Figure 2 The symbols are explained as follows: CX represents closing contactor; TX represents opening contactor; 3-X1 represents operating switch; SP1 represents closing position micro switch; SP2 represents opening position micro switch; M represents driving motor; ORE1, ORE2, ORE3 and OREX represent intelligent relay output contacts corresponding to switching elements; 3-A1, 3-A2, 3-AX represent switch operation application buttons; PLCRELAY represents programmable relay.

[0073] When the GIS switch element X is closed, the switch element to be operated is first selected through 3-AX, and logical judgment is performed through PLC RELAY. After the switch meets the operating conditions, the contact output (OREX) is used. The closing of OREX connects the motor circuit of the switch element to be operated in advance, which can also prevent OREX from directly connecting the motor starting current. After 3-X1 is closed, the motor circuit to be operated is connected and the motor starts. After the operation is in place, SP1 or SP2 sends the operation in place information for input. After PLC RELAY receives the signal input, it resets the OREX signal and cuts off the motor control circuit; the control method of other switch elements is the same.

[0074] It can be seen that the control method of a GIS switch device provided in this embodiment has a simple wiring of the control loop adopted by this method; the logic control adopts internal software compilation, and the control change is also quite flexible and convenient, avoiding complex wiring. In addition, the size of the component is small, and the size of an intelligent relay is the same as that of an ordinary relay, but it can replace the functions of several ordinary relays in terms of function, and can conveniently expand the logic and increase the control function. Low cost. The circuit that originally required several time relays and ordinary relays to complete can be completed with only one intelligent relay; strong function, in addition to the above main functions, this control method also has a strong expansion function. Due to the reduction of secondary components, the maintainability of the control loop is enhanced. This method reduces the complexity and reliability of the loop by changing the inherent one-to-one operation mode of GIS to a centralized operation mode. At the same time, the logical function of the control module is used to make the control loop extensible and engineering.

[0075] In summary, the present invention provides a control method for a GIS switch device, which has the following advantages over the existing detection methods:

[0076] First, improve operational safety: through logical judgment of preset conditions (including voltage conditions, interlocking conditions and the current state of the switch operating mechanism), ensure that the switch operation is performed only when all safety conditions are met, effectively prevent misoperation or operation in an unsafe state, thereby improving the safety and reliability of equipment operation.

[0077] Second, enhanced control flexibility: This method supports flexible control of different multi-switch elements in GIS switchgear. By repeatedly executing the steps of turning on the motor control loop and turning off the control loop, sequential or parallel control of multiple switch elements can be achieved, meeting the diverse needs in complex power systems.

[0078] Third, realize automatic control: the entire control process, from receiving the operation application signal, logical judgment, to connecting and disconnecting the motor control circuit, is automatically processed without direct human intervention, which improves work efficiency and reduces labor costs.

[0079] Fourth, improve the response speed: use programmable relays as the switch element control unit, combined with the micro unit (closed position micro switch and open position micro switch) to timely feedback the operation information, realize the rapid response to the state of the switch element, ensure the real-time and accuracy of the control; and effectively reduce the redundant components and redundant configurations of the traditional circuit, the reliability of the overall control system is improved and the maintenance difficulty is reduced.

[0080] Fifth, optimize system stability: By precisely controlling the connection and disconnection of the motor control circuit, equipment damage caused by long-term power-on or abnormal conditions is avoided, the service life of the equipment is extended, and system failures caused by improper operation are reduced, thereby improving the stability of the entire power system.

[0081] Sixth, easy maintenance and expansion: This method adopts modular and standardized design ideas, making the control system easy to maintain and expand. When it is necessary to change the control principle or add control functions, it is only necessary to adjust the control logic and configure the corresponding control parameters, without large-scale transformation of the system and changing the wire connection.

[0082] The above embodiment is only one of the implementation methods that can realize the technical solution of the present invention. The scope of protection claimed by the present invention is not limited only to this embodiment, but also includes changes, replacements and other implementation methods that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention.
