Description

Technical Field

[0001] The present invention relates to the technical field of intelligent monitoring devices, and in particular to an intelligent monitoring device for maintenance of power facilities. Background Art

[0002] Power facilities mainly include two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, mutual inductors, contactors, distribution cabinets, etc. Transformer oil of transformers is a mineral oil obtained by distillation and refining of natural petroleum. It is a mixture of pure, stable, low-viscosity, good insulation and good cooling properties obtained by acid and alkali refining of the lubricating oil fraction in petroleum.

[0003] When a serious fault occurs inside the transformer, strong gas is generated, causing the pressure in the oil tank to surge instantly. This generates a large amount of oil flow towards the oil pillow. As the oil flow impacts the baffle, the baffle swings and generates an alarm. At this time, the operator needs to come to inspect the transformer. On the oil circuit breaker and the transformer's on-load tap changer, an arc will be generated when the contacts are switched. Due to the good thermal conductivity of the transformer oil, a large amount of gas can be decomposed under the high temperature of the arc, generating a large pressure, which will trigger the alarm. This alarm is triggered for a short time, and the operator generally does not repair this situation, which creates a safety hazard. The current sampling and detection of transformer oil is not dispersed enough and the uniformity is not enough, resulting in inaccurate sampling and low precision. For this reason, we propose an intelligent monitoring device for power facility maintenance. Summary of the Invention

[0017] Beneficial effects

[0018] The present invention provides an intelligent monitoring device for power facility maintenance, which has the following beneficial effects:

[0019] (1) The intelligent monitoring device for power facility maintenance, in the initial state, when a serious fault occurs inside the transformer, the internal pressure of the transformer shell increases suddenly, which will generate a large oil impact in the direction of the oil pillow. The swing plate swings due to the flow of oil, and the swing plate squeezes the squeeze sensor. After the squeeze sensor is squeezed, an alarm signal is issued. When the alarm can be released in a short time, the fourth drainage chamber is moved to the inside of the transformer shell by the sliding tube to increase the detection frequency to avoid safety hazards. If the alarm is not released or the soluble gas inside the oil exceeds the standard during the detection, a signal is issued to rotate the rotating cylinder ninety degrees. By moving the first sliding block, the first guide chamber, the first sliding chamber and the inside of the third drainage chamber are connected. The oil inside the transformer shell can enter the inside of the guide tube through the first guide chamber, the third drainage chamber and the first drainage chamber in turn, so as to sample and analyze the oil at the upper and lower positions inside the transformer shell, thereby sampling the upper, middle and lower positions inside the transformer shell, improving the detection uniformity and improving the detection accuracy.

[0020] (2) The intelligent monitoring device for maintenance of electric power facilities closes the oil inlet channel of the first guide cavity by moving the extrusion rod during cleaning, and moves the third drainage cavity so that the fourth drainage cavity on the second sliding block moves to the position of the third drainage cavity so that the two first drainage cavities and the second drainage cavity are connected. At this time, cleaning liquid can be poured into one end of the sliding tube, and the cleaning liquid passes through the sliding tube, the fourth drainage cavity, and the third drainage cavity in turn into the interior of the first drainage cavity for flushing, which facilitates cleaning.

[0021] (3) The intelligent monitoring device for power facility maintenance has a temperature monitor located at the center of the transformer shell under normal use, and can be used to detect the temperature at the center of the transformer shell. When maintenance is performed, the connection block drives the temperature monitor to rotate ninety degrees. At this time, the two temperature monitors are moved by the connection block to the upper and lower positions of the transformer shell, respectively, to perform specific detection of the temperatures of the upper and lower layers of the transformer shell, and are flexible to use.

[0022] (4) The intelligent monitoring device for power facility maintenance is used. When the oil inside the transformer shell is changed, the transformer shell is disconnected from the power supply, and the rotating cylinder is in a state where it can move freely. The upper and lower sides of the connecting block can be supported and fixed by two connecting plates respectively, and the chamfered edges of the connecting block can be squeezed by two squeezing columns, thereby constraining the position of the connecting block and improving stability.

[0046] Working principle of the present invention:

[0047] When in use, in the initial state, when a serious fault occurs inside the transformer, the internal pressure of the transformer shell 111 increases suddenly, which will generate a large amount of oil impacting the direction of the oil pillow 113.

When the second sliding block 711 passes through the second drainage cavity 614, the two first drainage cavities 613 can be opened. The oil flows to the interior of the detection device for sampling. The oil inside the transformer shell 111 can enter the interior of the guide tube 615 through the first guide cavity 513, the third drainage cavity 616 and the first drainage cavity 613 in sequence, and then move to the interior of the detection device through the guide tube 615 for sampling and analysis. The sliding tube 712 slides inside the third sliding cavity 714 and the second sliding cavity 617. When the sliding tube 712 enters the interior of the transformer shell 111 with the fourth drainage cavity 713, the oil inside the transformer shell 111 can be sampled through the sliding tube 712.

[0048] When cleaning, push the first sliding block 611, which drives the extrusion rod 618 and the adapter block 619 to move, so that the oil inlet channel of the first guide chamber 513 is closed. At this time, move the second sliding block 711, and one end of the second sliding block 711 moves away from the position of the third drainage chamber 616, so that the two first drainage chambers 613 and the second drainage chamber 614 are connected. At this time, the position of the fourth drainage chamber 713 is at the position of the third drainage chamber 616. At this time, clean liquid can be poured into one end of the sliding tube 712.

The rotating cylinder 411 is rotated ninety degrees, and the rotating cylinder 411 drives the connecting rod 412 to rotate ninety degrees. The connecting rod 412 drives the connecting block 511 to rotate ninety degrees, and the connecting block 511 drives the temperature monitor 531 to rotate ninety degrees. At this time, the two temperature monitors 531 are respectively moved by the connecting block 511 to the upper position of the interior of the transformer shell 111 and the lower position of the interior of the transformer shell 111 to perform specific detection of the temperatures of the upper and lower layers of the transformer shell 111 respectively. The guide tube 615 can be moved with the first connecting movable sleeve 213, and the first sliding block 611 can be moved with the guide tube 615. The second connecting movable sleeve 214 can move with the sliding tube 712, and the oil inside the transformer shell 111 can enter the interior of the gas monitoring device 211 through the guide tube 615 and the first connecting movable sleeve 213 for analysis. The oil inside the transformer shell 111 can enter the interior of the gas monitoring device 211 through the sliding tube 712 and the second connecting movable sleeve 214 for analysis. When the rotating cylinder 411 rotates, the sealing structure 9 is used to seal the oil to prevent the oil inside the transformer shell 111 from leaking out. When the extrusion rod 618 moves inside the first guide cavity 513, when the extrusion rod 618 is removed from the second guide cavity 514, the liquid inside the transformer shell 111 can quickly flow through the second guide cavity 514, thereby improving the liquid feed port;

[0050] When changing the oil inside the transformer shell 111, the power supply of the transformer shell 111 is disconnected, and the rotating cylinder 411 is in a freely movable state. The upper and lower sides of the connecting block 511 can be supported and fixed by the two connecting plates 811 respectively, and the chamfered edges of the connecting block 511 can be squeezed by the two extrusion columns 816, so as to constrain the position of the connecting block 511 and improve stability.
