[0035] Please see Figures 1 to 2 The short -circuit test protection device for CT high voltage generator includes protection box 1, test plug 4 and fire extinguishing mechanism 2, wherein the protection box 1 is internally provided with a placing cavity for placing the high voltage generator to be tested, the test plug 4 is arranged on the cavity wall of the placing cavity for plugging on the high voltage generator, the fire extinguishing mechanism 2 includes sensor 24, storage box 21, conveying assembly 23 and fire extinguishing assembly 22, the sensor 24 is arranged in the placing cavity for detecting the temperature in the protection box 1, the storage box 21 is arranged on the protection box 1, and the storage box 21 is filled with fire extinguishing agent, one end of the conveying assembly 23 is arranged on the storage box 21, and the other end is provided with fire extinguishing assembly 22, and the fire extinguishing assembly 22 is used to spray fire extinguishing agent into the placing cavity.

[0036] When the high voltage generator needs to be short -circuit tested, first open the protection box 1 and put the high voltage generator into the protection box 1, and the socket of the high voltage generator is aligned with the test plug 4, so that the test plug 4 is plugged into the socket of the high voltage generator, then the protection box 1 is closed, then the test device is started to start the short -circuit test of the high voltage generator.

[0037] If the high voltage generator appears short -circuit fault during the short -circuit test of the high voltage generator, arc discharge will be generated, and the equipment will be heated, and the arc discharge caused by short circuit may cause the electric wire to catch fire and ignite the equipment, so that the equipment is completely damaged or even the test personnel is injured, therefore the fire extinguishing mechanism 2 is arranged, the temperature in the protection box 1 is detected by the sensor 24, when the temperature in the protection box 1 rises to a certain value, the storage box 21 transports the fire extinguishing agent to the fire extinguishing assembly 22 through the conveying assembly 23, the fire extinguishing assembly 22 receives the fire extinguishing agent and sprays towards the protection box 1, so as to perform the fire extinguishing work on the high voltage generator in the protection box 1.

[0038] Therefore, in the technical scheme, the fire extinguishing mechanism 2 comprises a sensor 24, a storage tank 21, a conveying assembly 23 and a fire extinguishing assembly 22, the sensor 24 is arranged in the placing cavity and is used to detect the temperature in the protection box 1, the storage tank 21 is arranged on the protection box 1, and the storage tank 21 is filled with fire extinguishing agent, one end of the conveying assembly 23 is arranged on the storage tank 21, and the other end is provided with the fire extinguishing assembly 22, the fire extinguishing assembly 22 is used to spray the fire extinguishing agent into the placing cavity, the sensor 24 is used to monitor the temperature in the protection box 1 in real time during the test, and when it is detected that the temperature in the protection box 1 is abnormal, the fire extinguishing assembly 22 is started to extinguish the fire, so that the equipment is prevented from being damaged and the test personnel are prevented from being injured after burning in the flame.

[0039] The conveying assembly 23 does not convey the fire extinguishing agent to the fire extinguishing assembly 22 at all times, so the start and stop of the conveying assembly 23 need to be limited, and specifically, in the embodiment of the utility model, the conveying assembly 23 comprises a conveying pipe 232 and a solenoid valve 231, one end of the conveying pipe 232 is arranged on the storage tank 21, and the other end is arranged on the fire extinguishing assembly 22, so as to convey the fire extinguishing agent in the storage tank 21 to the fire extinguishing assembly 22, and the solenoid valve 231 is arranged on the conveying pipe 232.

[0040] One end of the conveying pipe 232 is arranged on the storage tank 21, and the other end is connected to the fire extinguishing assembly 22, and the main function is to effectively convey the fire extinguishing agent in the storage tank 21 to the fire extinguishing assembly 22, and the solenoid valve 231 is installed at a proper position of the conveying pipe 232, so as to accurately control the flow of the fire extinguishing agent when needed, the solenoid valve 231 is started to open the conveying pipe 232 when the fire extinguishing is needed, and the conveying pipe 232 is closed when the fire extinguishing is not needed, so as to control the conveying of the fire extinguishing agent.

[0041] Further, the fire extinguishing assembly 22 comprises a connecting box 221 and a plurality of nozzles 222, the connecting box 221 is arranged on the cavity wall of the placing cavity, and the plurality of nozzles 222 are arranged on the connecting box 221 and are used to spray the fire extinguishing agent towards the placing cavity.

[0042] In order to ensure the spraying range of the fire extinguishing agent, a large number of nozzles 222 are needed to cooperate, and only one nozzle 222 can be installed on one conveying pipe 232, so a connecting box 221 is installed between the conveying pipe 232 and the nozzle 222 to transfer the fire extinguishing agent, a plurality of nozzles 222 can be installed on the same connecting box 221, and the conveying pipe 232 can also be installed in the same connecting box 221, so that the conveying pipe 232 can convey the fire extinguishing agent to the plurality of nozzles 222 at the same time, and the plurality of nozzles 222 can simultaneously spray the fire extinguishing agent to the inside of the protection box 1 to extinguish the fire.

[0043] Please refer to Figure 3 , the high-voltage generator has a metal part, and the high-voltage generator generates arc discharge when a short circuit occurs, so that the tester may be injured by the arc if directly touching the high-voltage generator, and therefore the high-voltage generator needs to be disconnected from the test device by means of other structures when moving the high-voltage generator, and the power supply is turned off, specifically, in the embodiments of the utility model, the moving assembly 5 is arranged on the protection box 1, and the moving assembly 5 is used to drive the high-voltage generator to move horizontally.

[0044] Further, the moving assembly 5 comprises a movable seat 51, the movable seat 51 is slidably arranged in the placing cavity, and the movable seat 51 is provided with a containing groove for placing the high-voltage generator, and has an electric connection position close to the test plug 4 and a power-off position away from the test plug 4 during horizontal sliding.

[0045] The high-voltage generator is placed on the movable seat 51, when testing, the movable seat 51 is moved towards the test plug 4 until the test plug 4 is inserted into the socket of the high-voltage generator, and then the test device is started to test, when the plug is pulled out, the movable seat 51 is moved away from the test plug 4 to make the test plug 4 separate from the high-voltage generator and make the high-voltage generator power off, and the test personnel can insert or pull out the test plug 4 from the high-voltage generator without touching the high-voltage generator by means of the movable seat 51, thereby reducing the possibility of injury of the test personnel.

[0046] Further, the moving assembly 5 further comprises a driving member 52 arranged on the movable seat 51, and the driving member 52 is used to drive the movable seat 51 to move horizontally to drive the high-voltage generator to move towards the electric connection position or the power-off position.

[0047] The high-voltage generator may generate arc discharge when a short circuit occurs, and therefore the tester may be injured by the current when the hand is close to the high-voltage generator, and therefore the high-voltage generator needs to be moved away from the high-voltage generator, and the distance between the movable seat 51 and the high-voltage generator is too close, and the movable seat 51 is easy to be hit by the current, and therefore the driving member 52 is arranged to push the movable seat 51 to drive the high-voltage generator to move to complete the connection or separation of the high-voltage generator and the test plug 4.

[0048] Further, the protection box 1 is provided with a movable hole for the driving member 52 to penetrate.

[0049] When the high-voltage generator appears a short-circuit fault, the current is discharged, so that the personnel around and the equipment can be shocked, therefore, the short-circuit test of the high-voltage generator is carried out in the closed protective box 1, so that the current can only concentrate on the inner cavity wall of the protective box 1, but the high-voltage generator needs to be driven to move to complete the connection with the test device, therefore, a through hole matched with the driving piece 52 is formed on the protective box 1, so that the driving piece 52 can extend to the outside of the protective box 1 through the through hole, and the test personnel can control the high-voltage generator to move horizontally through the driving rod located outside the protective box 1, so that the high-voltage generator is connected with or separated from the test plug 4.

[0050] In addition, in order to ensure the safety of the test process, the material selection of the protective box 1 is also limited, and materials with high insulation performance are usually used, such as polycarbonate or polytetrafluoroethylene, which can not only effectively isolate the current, but also can withstand high temperature and high pressure environment, and ensure the structural stability and safety of the protective box 1 under extreme conditions.

[0051] In order to further improve the convenience and safety of operation, the protective box 1 is also provided with observation windows, which are usually made of explosion-proof glass, allowing the test personnel to observe the working state of the high-voltage generator without opening the protective box 1, in addition, the design of the observation window also considers the problem of light refraction and reflection, ensuring clear vision when observing, reducing the possibility of misjudgment.

[0052] The high-voltage generator not only causes a fire when a short circuit occurs, but also can cause the device to overheat, thereby causing the temperature inside the protective box 1 to rise, in order to exclude the temperature rise caused by the overheat of the device, a corresponding device needs to be set, specifically, in the embodiment of the utility model, the protective box 1 is provided with a heat dissipation mechanism 3 for reducing the temperature in the protective box 1.

[0053] Further, the protective box 1 is provided with a mounting hole, the heat dissipation mechanism 3 includes a fan 31 arranged in the mounting hole, and the protective box 1 is provided with a ventilation hole 32 for air circulation.

[0054] The mounting hole is arranged to accommodate and fix the key components in the heat dissipation mechanism 3, specifically, the fan 31 is installed in the mounting hole, and the fan 31 is an important part of the heat dissipation mechanism 3, which is responsible for extracting hot air from the inside of the protective box 1 to reduce the temperature in the box and ensure the normal operation of the internal equipment, in addition, in order to ensure that the fan 31 can effectively dissipate heat, the protective box 1 is specially designed with ventilation holes 32 at the corresponding position, which can provide sufficient air circulation path for the fan 31, so that the hot air can be smoothly discharged, and at the same time, fresh cold air can enter the box, forming a good air circulation system.

[0055] The heat dissipation mechanism 3 needs to be used in cooperation with the fire extinguishing mechanism 2, so the heat dissipation mechanism 3 and the fire extinguishing mechanism 2 need to be linked, specifically, in the embodiment of the utility model, the sensor 24 is electrically connected with the fan 31.

[0056] When the sensor 24 detects that the temperature in the protection box 1 rises to a set value, the fan 31 is started to reduce the temperature in the protection box 1, and when the temperature in the protection box 1 does not drop to the set temperature within a set time, the fan 31 is closed, and the fire extinguishing mechanism 2 is started to perform fire extinguishing work, so that the heat dissipation mechanism 3 and the fire extinguishing mechanism 2 are linked and started, and the heat dissipation work and the fire extinguishing work do not interfere with each other.

[0057] The above is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and the attached drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
