INSTRUCTIONS: [Technical Field] The present invention relates to a pressure test device, and more particularly to a water pressure test device suitable for a Gas Insulated Switchgear (GIS) [Prior Art] General sealed container After the welding process, the leak test is required, that is, the leak test. In addition, it is necessary to carry out the pressure strength test for the liquid transfer line. Needle 10 For the above verification work, the conventional test method, such as the ventilation test, has the potential disadvantage of being an air-compressible fluid, which may cause a gas explosion if inadvertently pressurized, resulting in an on-site safety event. Therefore, a hydrostatic test method was proposed, which focused on the characteristics of water as an incompressible fluid to ensure the safety of the test process. 15 . The conventional hydrostatic test is to first fill the container with water, and then manually pressurize the water in the container directly using a manual supercharger. However, the above J money method takes too long and requires a large number of instruments, for example, it takes time in the pressurization process, and the display on the pressure gauge is visually focused to match the target pressure of 20 people; another disadvantage is, for example, During each test and manual il repair installation of the electric fruit or manual supercharger to the container under test, the pressure may be too high to cause deformation of the container.

The other end is used to connect a test container. The upper device is electrically connected to the pressure switch and the pressure pump. When the buffer tank is reached, the force pressure switch triggers the controller, so that the controller stops the pressure pump. H design, buffer before the container pressure test After the liquid phase is added to the test pressure and confirmed, the pressurization process is performed on the container to be tested, so that the test condition accuracy is better, and the test safety is also taken into account. The hydraulic test system may further include a timer, and : electric = device, and the external pipe is closed and closed. It is also connected to = trigger = alarm, so that the operator knows: 2: the above-mentioned connecting pipe can include a high-shell snake body insulation switch envelope The liquid dust test system can be further packaged: 2:, with a return valve, the return line is connected: - the flow valve set is set in the return line. Phase /, buffer liquid liquid 'back hydraulic test system can It also includes a liquid pipe and a liquid 1 20 200923359 liquid pipe is connected to the liquid tank 'new valve is set in the manifold. The buffer tank can be further equipped with a pressure relief valve for proper pressure reduction. The liquid phase may include a supplemental hole and the reservoir is on the outer surface A transparent window is provided for observing the liquid level state. 5 The hydraulic test system can further include a liquid source, a liquid source, a liquid source, a liquid source, and a liquid source, and a liquid source opening and closing valve group disposed therebetween. Mode 1 Referring to FIG. 1 ' is a block diagram of a hydraulic test system 10 according to a preferred embodiment of the present invention. As shown, the hydraulic test system includes a reservoir 11 , a main line opening and closing valve 12 , and a pressurization The pump 13, the check valve 14, the buffer tank 15, the controller 20, a timer 21, an alarm 22, an external line opening and closing valve 19, a return valve 36, and a drain valve 38 a liquid source 33, and a liquid source opening and closing valve 39. This embodiment is a hydraulic pressure test for applying a test system to a gas insulated device. The liquid storage tank 11, the pressure pump 13, and the buffer tank 15 is sequentially connected through a main line 30, wherein the main line opening and closing valve 12 is disposed between the liquid storage tank u and the pressure pump 13, and controls the liquid circulation between the liquid storage tank 11 and the pressure pump 13 The check valve 14 is disposed between the pressure pump 〖3 and the buffer tank 15. The 〇 reservoir 11 body has a supplementary hole 丨i, the liquid in the tank is replenished through the hole; and a transparent window 112 is also disposed on the outer surface for observing the liquid level state in the tank. The liquid storage tank is connected with a liquid discharge pipe 37 for discharging the liquid to the outside. And the liquid discharge valve 38 is assembled on the liquid discharge pipe 37, and the liquid storage tank u needs to be kept at atmospheric pressure, and a small pore can be opened at the top end. 200923359 The buffer tank 15 body group is provided with a pressure gauge 16 for instant reflection. The pressure inside the box, the exhaust valve 17, and the pressure switch π. The exhaust valve U is used to eliminate unnecessary air to maintain a simple water flow environment. In this example, a mechanical pressure shutoff 18 is used. The pressure of the liquid 5 in the buffer tank 15 is sensed to timely send a trigger signal to the controller for use. The buffer tank is further connected to the reservoir u through a return line 35, and the return line 36 is sighed by the return valve 36. In order to have a pressure relief path for the buffer tank 丨 5, a pressure relief valve 23 is also provided thereon. The control person 20 is electrically connected to the pressure switch 18. By setting the pressure switch 1〇18 in advance, when the pressure switch 18 is subjected to a certain pressure, the mechanical action therein will turn on the circuit between the pressure switch 18 and the controller 2〇 as the trigger controller 20 Trigger signal. The controller 2 is additionally electrically connected to the pressurization collector 13, and a device incorporating the timer 21 and the alarm 22, and when the controller 20 is triggered, the pressure pump 13 is controlled to stop. The 15' buffer tank 15 is also connected to the container under test 34 through the external line 31, in this case a gas insulated switch enveloping the outer casing. The above-mentioned external pipeline opening and closing is verified to be connected to the external pipeline 31±, and the core (four) buffer (four) Lang is connected to the pipeline between the measuring vessels 34. In this example, the outer pipe 31 is used to facilitate the disassembly and assembly of the gas-insulated switch enveloping casing; the external pipe 20-way opening and closing valve 19 is a solenoid valve' electrically connected to the controller 2'. a Since the container to be tested 34 is pre-filled with liquid before being pressurized, a line-injection line 32 is also bypassed on the external line 31, which is connected to a liquid source 33, such as ground water. The above-mentioned liquid source opening and closing interval % is set on the liquid injection line 32. 200923359 The operation of the test system is described below with reference to Fig. 1 and Fig. 2. Fig. 2 is the main component operation state table of the hydraulic test system. The main components are preset to be off in the initial state. First in the steps! In the middle, the liquid source opening and closing valve 39 is opened to fill the ground water to the container 34 to be tested until it is full. Next, in step 2, the liquid source closing valve 39 is closed and held for about one minute to stabilize it. In fact, the link to the GIS can be connected to the water before or after the automatic test phase described below, without affecting the test. In step 3, the main pipe opening and closing valve 12 and the exhaust valve 17 are opened, and water is supplied through the replenishing hole 1 1 1 to the tank 使其 to be full. Next, the pressurizing pump 13 is started in step 4 of step 10, and the pump is pumped to the buffer tank 15 by the pressurizing pump 13 to be full. When the air in the buffer tank 15 has actually been discharged through the exhaust valve 17, it is convenient to close the exhaust valve 17 in step 5, and the pressurizing pump 13 continues to operate at the same time to raise the water pressure in the buffer tank 15. When the water pressure in the buffer tank 15 rises to a specific pressure value set in advance by the pressure opening 15 off 18, in this example, 12 kg/cm 2 , the controller is electrically connected between the pressure switch 18 and the controller 20, so that the controller When the trigger is triggered, the pressure pump 13 is controlled to stop operating. Due to the check valve 14, the pressure in the buffer/tank 15 is regulated at a specific pressure. Read the pressure gauge “You can confirm that the water pressure is the desired pressure. Therefore, the above steps 3 to 5 are equivalent to the 2 〇 system and the water pressure control. ^ After confirming the pressure value, proceed directly to step 6, and connect the outer tube. When the opening and closing compartment 19 is opened to allow the buffer tank 15 to communicate with the container under test 34, the container to be tested is thus subjected to the above-mentioned high water pressure. Immediately after the step 7, the pipelines are interconnected so that the pressure balance takes only a short time. After the intercommunication, the external pipe 9 200923359 opening and closing valve 19 can be closed again, and the container under test 34 is maintained under the high water pressure state for a suitable period of time, depending on the specification, for example, 3 minutes. For example, when the external pipe opening and closing valve 19 is opened, the controller 2 is triggered, and the controller 20 controls the timer 21 to start timing. When the timer is called, the setting is delayed by 5, and after the interval, the The alarm device 22 is triggered to issue an alarm, for example, an singer sound or a flashing light signal to inform the operator that the test is over. When a certain time has elapsed, in step 8, the external pipe opening and closing valve 19 and the return valve are connected. 36 simultaneously open, carry out reflow, (four), so that Flowing back to the storage tank 11. When the reflow process is completed, the external pipe opening and closing 10 19 and the return valve 36 are closed again in step 9. The foregoing embodiment except the container 34 to be tested, the liquid source 33, and the liquid source The other components can be integrated on the mobile device to provide a more flexible and convenient application. The hydraulic test system of the present invention can obtain the effect of self-testing, 15 Make sure that the hydraulic pressure is correct and avoid damage to the test product caused by excessive pressure. In addition, the operator does not need to have long pressure values as in the prior art, and does not need to re-pipe each test. 'Annon related equipment is more convenient and efficient. The invention is applicable to the withstand voltage test of various sealed casings, and is not limited to GIS, and the pump of the higher capacity can be replaced according to the test requirement, and the pressure pipeline is adapted to the invention. The above-mentioned embodiments are merely examples for convenience of description, and the scope of the claims is based on the above-mentioned embodiments, which are based on the scope of the patent application. 200923359 [Simplified description of the drawings] FIG. 1 is a comparison of the present invention.
