Description

Dual monitoring system for opening and closing of self-generating gas valves

[0001] The present invention relates to a dual monitoring system for opening and closing a self-generating gas valve, and more specifically, to a dual monitoring system for opening and closing a self-generating gas valve that generates self-generation according to the opening and closing operation of the gas valve to immediately monitor the opening and closing status of the gas valve wirelessly, thereby improving safety through rapid response.

[0002] SF6 gas is used to fill the interior of Gas Insulator Switchgear (GIS) operating in power systems due to its excellent insulation performance and superior arc extinguishing ability during circuit breaker operation.

[0003] Since GIS is a core device that receives power from substations to connect to the system and supplies power converted to an appropriate voltage through large transformers, performance is maintained and functions are restored through regular precision inspections and repairs in case of equipment malfunction.

[0004] Due to the characteristics of power supply at substations, such precise inspections and repairs require that only a part of the equipment (the relevant device) be shut down for the work, and the work must be carried out after recovering the sulfur hexafluoride (SF6) gas filling the inside of the device by opening the valve of the device.

[0005] Generally, there are about 12 SF6 gas valves per GIS unit. When recovering SF6 gas, only the relevant valve must be opened to recover the gas from that specific device. In situations where multiple devices are mixed in a confined space, the SF6 gas piping is complexly configured, and the valves for the devices are installed separately from the gas tanks in the LCP (Local Control Panel). Consequently, confusion between the valves for the off-line device (the device being worked on) and the valves for the live-line device is causing not only major power outages but also worker safety accidents.

[0006] Such accidents cause disruptions in power supply due to total substation blackouts and delays in restoration, resulting in losses from electricity sales as well as hindering production activities in the national economy.

[0007] Furthermore, although numerous valves such as gas-insulated switchgear, main transformers, and air pressure valves are used during substation inspections, there are significant difficulties in these inspections because the open / closed indicators cannot be visually confirmed and the status can only be determined by manually turning the handle. Although there have been frequent cases where the inaccurate assessment of valve status during inspections has led to gas leaks and equipment failures, there are currently no countermeasures in place.

[0008] Furthermore, while systems capable of electronically operating and verifying the opening and closing status of valves, such as through wiring-connected limit switches, are currently being developed, it is necessary to minimize the application of electronic systems to reduce risk due to the environmental characteristics of substations where gas flows through pipelines. Moreover, even if the application of electronic systems were feasible, there is a problem in that implementing them requires significant time and cost.

[0009] The present invention aims to solve the aforementioned problems by providing a self-generating gas valve opening / closing dual monitoring system that improves safety and operational efficiency. This is achieved by connecting a self-generating gas valve opening / closing sensor capable of self-generation to the gas valve, generating self-generation according to the opening / closing operation of the gas valve, and sending a signal to a wireless receiver to monitor and immediately notify the opening / closing status of the gas valve. This prevents accidents caused by gas valve malfunction and enables a rapid response.

[0122] Additionally, the shaft (3100) may have a male screw thread (3110) formed on the outside to be screw-assembled with the shaft ring (3200), a recessed groove (3120) formed on the lower outer side into which the plate spring (5200) of the self-generating unit (5000) is fitted, and a connecting groove (3130) formed on the lower inner side to be connected to the gas valve (1).

[0123] Meanwhile, an O-ring (R) may be provided around the shaft (3100) to maintain airtightness with the cover (2200).

[0124] The shaft ring (3200) is provided in the receiving portion (2110) of the case (2100) and is assembled by wrapping around the outside of the shaft (3100). At this time, a female screw thread (3210) for assembling the male screw thread (3110) of the shaft (3100) may be formed on the inner circumference of the shaft ring (3200).

[0125] Additionally, the shaft ring (3200) is formed to penetrate vertically so that the shaft (3100) can be inserted, and its side can be opened so that the plate spring (5200) of the self-generating unit (5000) can be connected to the recessed groove (3120) of the shaft (3100).

[0126] The handle (3300) is coupled to the upper part of the shaft (3100) and rotates the shaft (3100) to open and close the gas valve (1).

[0127] The above self-generating unit (5000) is installed in the receiving unit (2110) of the case (2100) and generates power through the rotational operation of the operating unit (3000) and transmits wirelessly to the receiving unit (20).

[0128] Referring to FIG. 14, the self-generating unit (5000) includes a self-generating module (5100), a leaf spring (5200), and a transmission module (5300).

[0129] The above-mentioned self-generating module (5100) is provided within the receiving portion (2110) of the case (2100) to convert mechanical displacement into electricity and enable self-generation. Meanwhile, the self-generating module (5100) generates self-generation by inducing an induced current through the movement of a magnet and a coil according to Faraday's law. Since this method is already widely used, the technical configuration and operating principle thereof will be omitted.

[0130] The above leaf spring (5200) is connected to the shaft (3100) of the operating unit (3000) in the self-generating module (5100) and operates the self-generating module (5100) according to the rotation of the shaft (3100).

[0131] The above-mentioned transmitting module (5300) is electrically connected to the self-generating module (5100) to receive the output generated from the self-generating module (5100) and send a wireless signal to the receiving unit (20).

[0132] The receiver (20) monitors whether the gas valve (1) is open or closed by receiving wireless communication from the transmission module (530, 5300) according to the operation of the self-generating gas valve opening / closing detector (10, 10-1). That is, the receiver (20) receives the detection signal of the self-generating gas valve opening / closing detector (10, 10-1) as a radio frequency (RF) signal and transmits the received signal to the application unit (30).

[0133] Additionally, when the self-generating gas valve opening / closing detector (10, 10-1) is activated, the receiver (20) displays the location number of the area where the gas valve (1) is open on the monitor and sends a signal to the application unit (30) using a communication module (e.g., a signal indicator (485 communication) or a repeater).

[0134] The above application unit (30) receives a signal from the receiving unit (20), uses a monitor and a relay module to indicate whether the gas valve (1) is open or closed, and is connected to a server to check registered signals, thereby preventing gas accidents caused by misoperation of the gas valve (1).

[0135] In addition, the LCD monitor of the application unit (30) receives a signal from the signal indicator and can check whether the gas valve is open or closed on-site. The contact provision part of the relay module is applied universally to ensure compatibility with solutions for companies and public institutions, and the open / closed status of each gas valve (1) is applied in a compatible manner through the contacts of the relay module in the existing SCADA (central control system) owned by the company. Accordingly, it can be applied in a compatible manner to existing systems rather than as a separate application.

[0136] Meanwhile, the registration of the self-generating gas valve opening / closing detector (10, 10-1) of the present invention is achieved by rotating the handle (320, 3300) so that when the gas valve (1) is opened / closed, the self-generating module (510, 5100) operates and sends a wireless signal to the receiver (20) to register each self-generating gas valve opening / closing detector (10, 10-1).

[0137]

[0138] As described above, in the present invention, as the shaft (310) rotates according to the rotation of the handle (320), the push button (420) rises, and the plate spring (520) in contact with the push button (420) is lifted, causing the self-generating module (510) to operate and instantaneously generate self-generation, and the output generated from the self-generating module (510) is received by the transmission module (530) and wirelessly sends an RF signal to the receiver (20).

[0139] Then, the signal indicator of the receiver (20) receives a wireless signal, and the signal indicator displays a notification number on the signal indicator screen window and transmits the received signal to the application unit (30) as a communication signal. Upon receiving the communication signal, the field manager can check through the monitor whether the opening / closing of the gas valve (1) has operated correctly. In addition, through the relay module, it is possible to immediately check which gas valve (1) at which location has been opened or closed.

[0140] Accordingly, the opening and closing status of the gas valve (1) is immediately detected by the self-generating unit (500, 5000) in accordance with the operation of the self-generating gas valve opening and closing detector (10, 10-1), and a signal is sent to the receiving unit (20), so that a large number of people can easily determine at a glance whether the gas valve (1) is open or closed through the application unit (30).

[0141] In addition, a fixed guide (100, 1000) is fixed to the gas valve (1), and a self-generating unit (500, 5000) containing a self-generating module (510, 5100) capable of self-generating power is installed on the fixed guide (100, 1000). By connecting an operating unit (400) and a control unit (3000) for opening and closing the gas valve (1) to the self-generating unit (500, 5000), it is possible to install a self-generating gas valve opening / closing detector (10, 10-1) without removing the existing gas valve, thereby making installation and disassembly convenient.

[0142] In addition, a self-generating module (510, 5100) capable of self-generating power is embedded inside the body part (200, 2000) to determine whether the gas valve (1) is open or closed through self-generation, thereby allowing for semi-permanent use without a separate wired connection.

However, it should be understood that the present invention is not limited to the specific forms mentioned in the detailed description, but rather should be understood to include all variations, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.

[0145] In other words, the present invention is not limited to the specific embodiments and descriptions described above, and any person skilled in the art to which the present invention pertains can make various modifications without departing from the essence of the invention as claimed in the claims, and such modifications fall within the scope of protection of the present invention.
