Description

Technical Field

[0001] This utility model relates to the field of ignition transformers, and in particular to a stabilizing mechanism for a gas turbine ignition transformer. Background Technology

[0002] Current gas turbine ignition transformers have a defect during operation: the negative terminal of the secondary coil of the ignition transformer requires grounding. The grounding is achieved by connecting an iron plate to the negative terminal of the secondary coil, and then tightening the connector of the ignition cable to make the iron plate fit against the housing, thereby grounding through the housing. After long-term operation of the unit, the connector may loosen, resulting in poor contact between the grounding iron plate and the housing, leading to poor grounding and ultimately unsuccessful ignition. Therefore, a gas turbine ignition transformer stabilization mechanism is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a stabilizing mechanism for gas turbine ignition transformers, which solves the problem that the contact plates of current ignition transformers are prone to loosening.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A gas turbine ignition transformer stabilization mechanism, comprising:

[0006] Box; and

[0007] A connecting plate is provided on one side of the inner wall of the box. Both the connecting plate and one side of the box are provided with screw holes. The screw holes on the box and the connecting plate correspond to each other. A fixing member is inserted into the inside of the screw hole.

[0008] Furthermore, the fastener is configured as a fixing bolt, the thread of which is connected between the receiving plate and the housing.

[0009] Furthermore, the number of screw holes is set to two sets, with the two sets of screw holes being opened opposite each other on the contact plate and the housing.

[0010] Furthermore, two mounting holes are provided on one side of both the connecting plate and the housing, and the mounting holes on one side of the connecting plate and the housing correspond to each other, with the two mounting holes being provided in a front-to-back correspondence.

[0011] Furthermore, an ignition cable is provided on the outside of the enclosure, with one end of the ignition cable inserted into the mounting hole and into the interior of the enclosure.

[0012] Furthermore, the ignition cable is externally mounted with two cable connectors, which are respectively installed on the connector sheet and the housing, and the cable connectors correspond to the mounting holes.

[0013] Furthermore, a terminal block is installed at the bottom of the inner wall of the enclosure, and one end of the ignition cable located inside the enclosure is connected to the terminal block.

[0014] Furthermore, the external thread of the terminal block is connected to a fastening nut, which is pressed against the ignition cable.

[0015] Furthermore, the terminal block is covered with an insulating sleeve, which wraps around the end of the ignition cable located inside the housing.

[0016] Furthermore, the gas turbine ignition transformer includes an ignition transformer body, which is connected to the terminal block.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The enclosure and the grounding plate are connected by screw holes and fixing bolts to ensure a tight fit between them.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model embodiment provides a gas turbine ignition transformer stabilization mechanism. Please refer to [link / reference]. Figures 1-3It includes: a housing 1 and a connecting piece 2. The connecting piece 2 is located on one side of the inner wall of the housing 1. Both the connecting piece 2 and the housing 1 have screw holes 202 on one side. The screw holes 202 on the housing 1 and the connecting piece 2 correspond to each other. A fastener is inserted into the screw hole 202.

[0031] like Figures 1-3 As shown, the housing 1 serves as the main load-bearing structure of the stabilizing mechanism, providing installation space and support for other components, protecting internal components from direct interference and damage from the external environment, and also playing a certain role in electromagnetic shielding, reducing the impact of external electromagnetic fields on internal electrical components such as the ignition transformer.

[0032] The main function of grounding plate 2 is to electrically connect the enclosure 1 and the entire ignition transformer stabilization mechanism to the ground, thereby achieving the grounding function. During equipment operation, it can introduce any static electricity, leakage current, or other currents that may be generated into the ground, preventing damage to equipment or personnel due to charge accumulation or leakage.

[0033] The screw hole 202 provides a fixed position for the connection between the grounding plate 2 and the enclosure 1. By inserting a fastener into the screw hole 202, the grounding plate 2 can be firmly installed on the enclosure 1, ensuring good electrical contact and mechanical connection between the grounding plate 2 and the enclosure 1. This guarantees the stability and reliability of the connection between the grounding plate 2 and the enclosure 1, allowing the grounding function to function continuously and effectively. At the same time, this connection method is easy to install and disassemble, which is beneficial to the maintenance and repair of the equipment. Furthermore, the design of the corresponding screw holes 202 allows the fastener to be accurately inserted and pass through both the enclosure 1 and the grounding plate 2, achieving a precise connection between the two.

[0034] The fastener (such as the fixing bolt 201) tightly connects the grounding plate 2 and the housing 1 together through the threaded engagement with the screw hole 202. It bears the force between the grounding plate 2 and the housing 1, prevents the grounding plate 2 from loosening or falling off during use, provides a reliable mechanical connection, ensures a long-term stable connection between the grounding plate 2 and the housing 1, ensures that the grounding function is always in good condition, and provides a strong guarantee for the safe operation of the equipment.

[0035] Operation process: First, place the grounding plate 2 on the designated side of the inner wall of the housing 1, aligning the screw hole 202 on the grounding plate 2 with the corresponding screw hole 202 on the housing 1. Then, insert the fixing component (such as the fixing bolt 201) into the screw hole 202, and rotate the fixing bolt 201 to make its screw threadedly connect with the screw hole 202 on the grounding plate 2 and the housing 1. Gradually tighten the fixing bolt 201 until the grounding plate 2 is firmly fixed to the housing 1. At this time, good electrical contact and mechanical connection are achieved between the grounding plate 2 and the housing 1, and the entire stabilizing mechanism is initially installed. During the operation of the equipment, the grounding plate 2 will introduce any current that may be generated into the ground at any time to ensure the safe operation of the equipment.

[0036] Please continue reading. Figures 1-3 The fastener is set as a fixing bolt 201. The screw of the fixing bolt 201 is threaded between the receiving plate 2 and the housing 1. The number of screw holes 202 is set as two sets, and the two sets of screw holes 202 are opened on the receiving plate 2 and the housing 1 in opposite directions.

[0037] like Figures 1-3 As shown, the fixing bolt 201 includes a screw and a screw head. Through the threaded engagement of its screw with the threaded hole 202 on the grounding plate 2 and the housing 1, the grounding plate 2 is tightly fixed to one side of the inner wall of the housing 1. This threaded connection method can provide strong mechanical tensile force to ensure that the grounding plate 2 will not loosen or fall off due to vibration, shaking or other factors during equipment operation. In addition to achieving mechanical fixation, the fixing bolt 201 can also ensure good electrical contact between the grounding plate 2 and the housing 1. Because the metal fixing bolt 201, the grounding plate 2 and the housing 1 are tightly connected to each other, the current can be smoothly conducted between them, thereby achieving a reliable grounding function and introducing any static electricity, leakage current and other currents that may be generated into the ground, ensuring the safety of equipment and personnel.

[0038] The design of two sets of front and rear opposite screw holes 202 makes the fixing of the connecting piece 2 on the housing 1 more secure. Through the combined action of the two sets of fixing bolts 201, the force on the connecting piece 2 can be dispersed, reducing the stress concentration at a single fixing point, thereby improving the stability of the connection between the connecting piece 2 and the housing 1 and preventing the connecting piece 2 from tilting, shaking or deforming during use.

[0039] Please see Figure 1Two mounting holes 203 are provided on one side of the connecting plate 2 and the box 1. The mounting holes 203 on the side of the connecting plate 2 and the box 1 correspond to each other. The two mounting holes 203 are provided in front and behind. An ignition cable 4 is provided on the outside of the box 1. One end of the ignition cable 4 is inserted into the inside of the mounting hole 203 and into the inside of the box 1. Two cable connectors 3 are installed on the outside of the ignition cable 4. The two cable connectors 3 are respectively installed on the connector sheet and the box 1. The cable connectors 3 correspond to the mounting holes 203.

[0040] like Figure 1 As shown, the corresponding mounting holes 203 provided with a channel for the ignition cable 4 to enter the interior of the housing 1, allowing the ignition cable 4 to smoothly pass through the interior of the housing 1 from the outside and connect with other components inside the housing 1. This is an important part of the electrical connection of the ignition system.

[0041] The ignition cable 4 is a key component in the gas turbine ignition system. Its main function is to transmit ignition energy from the external power source to the terminal 7 inside the housing 1, thereby providing the required electrical energy to the ignition transformer and realizing the ignition function of the gas turbine.

[0042] The function of the cable connector 3 is to make an electrical connection between the ignition cable 4 and the contact plate 2 and the box 1. By installing the cable connector 3 on the connector sheet and the box 1 respectively, a more stable and reliable electrical contact can be provided, reducing contact resistance, reducing power loss, and improving electrical transmission efficiency.

[0043] Please continue reading. Figure 1 A terminal block 7 is installed at the bottom of the inner wall of the housing 1. One end of the ignition cable 4 located inside the housing 1 is connected to the terminal block 7. A fastening nut 6 is threaded on the outside of the terminal block 7. The fastening nut 6 is pressed onto the ignition cable 4. The gas turbine ignition transformer includes an ignition transformer body 8, which is connected to the terminal block 7.

[0044] like Figure 1 As shown, terminal 7 is the key hub for the electrical connection of the entire ignition system. It concentrates and distributes the electrical energy transmitted from ignition cable 4. After ignition cable 4 introduces the electrical energy from the external power source into the housing 1, it transmits the electrical energy to the ignition transformer body 8 through connection with terminal 7, providing the necessary energy for the ignition of the gas turbine.

[0045] The fastening nut 6 is threaded onto the terminal 7 and applies pressure to the ignition cable 4, making the contact between the ignition cable 4 and the terminal 7 tighter. This tight contact can reduce contact resistance, reduce power loss, improve power transmission efficiency, and ensure that the ignition system receives a stable and sufficient power supply.

[0046] The ignition transformer body 8 is the core energy conversion component of the entire ignition system. It converts the low-voltage electrical energy into high-voltage electrical energy to meet the energy requirements of the gas turbine ignition and achieve reliable ignition of the gas turbine.

[0047] Please continue reading. Figure 1 The terminal block 7 is covered with an insulating sleeve 5, which wraps around one end of the ignition cable 4 located inside the housing 1.

[0048] like Figure 1 As shown, the primary function of the insulating sleeve 5 is to provide electrical insulation. In the stabilizing mechanism of the gas turbine ignition transformer, the terminal 7 connects the ignition cable 4 and the ignition transformer body 8, and current will pass through it. The insulating sleeve 5 can prevent the current from being conducted from the terminal 7 to other unnecessary components or the housing 1 around it, prevent leakage, avoid short circuits, electric shocks and other safety accidents caused by leakage, and ensure the electrical safety of the entire ignition system.

[0049] The end of the ignition cable 4 located inside the housing 1 is a critical part of the electrical connection and also an area prone to insulation problems. The insulating sheath 5 wraps around this part, which can enhance the insulation strength of this area and further improve electrical safety. Even if the insulation of other parts is damaged, it can provide additional insulation protection for the ignition cable 4.

[0050] In another embodiment, a groove 9 is provided at the bottom of the inner wall of the housing 1, and multiple sliders 10 slide inside the groove. Each slider 10 includes a bottom block that slides inside the groove 9 and a base fixedly connected to the top of the bottom. The base is located above the groove 9, and the groove 9 is opened horizontally, so that the sliders 10 can slide horizontally inside the groove 9. At the same time, two clamping blocks 11 rotate on the base. The clamping blocks 11 have an inverted U-shaped structure, so that the ignition cable 4 can pass through the clamping blocks 11. The clamping blocks 11 limit and fix the ignition cable 4, ensuring that when the ignition transformer body 8 vibrates and pulls the ignition cable during ignition, the ignition cable 4 can be fixed, further improving the stability between the grounding plate 2 and the housing 1. The clamping blocks 11 can also fix and organize the ignition cable 4 to prevent tangling. The two clamping blocks 11 are connected by a magnet, which makes it more convenient to disassemble and assemble the ignition cable 4.

[0051] A slot 1001 is provided on the base of the slider 10, and movable slots 12 are provided on the front and back of the inner wall of the slot 1001. Movable blocks are provided inside the two movable slots 12, and a roller 14 is rotatably connected between the two movable blocks. The outer side of the roller 14 is located inside the clamping block 11 to ensure smoother entry of the ignition cable 4. A spring 13 is provided inside the movable slot 12. The spring 13 abuts against the movable block. After the ignition cable 4 is installed, the clamping block 11 rotates and fixes the ignition cable 4. The ignition cable 4 presses down on the roller 14, so that the roller 14 enters the slot 1001. This ensures that after the ignition cable 4 is installed, the roller 14 will not cause the ignition cable 4 to move easily.

[0052] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
