Description

Technical Field

[0001] The invention relates to the technical field of pole-mounted circuit breakers, in particular to an intelligent primary-secondary fusion pole-mounted circuit breaker. Background Art

[0002] The existing intelligent primary and secondary fusion pole-mounted circuit breakers are installed and operated on poles. They are usually installed in outdoor environments. Snow easily accumulates on the surface during winter use. Snow adheres to the surface of the circuit breaker body and easily exerts additional pressure on the mechanical parts such as the casing and bracket of the circuit breaker. Long-term exposure to such additional loads can easily cause deformation and damage of the parts, affecting the structural stability and normal operation of the equipment. In addition, snow easily freezes and hardens, which reduces the gap between parts and even freezes them, increasing the operating resistance, making the circuit breaker difficult to open and close or even unable to operate normally, resulting in the failure to cut off the circuit in time when a fault occurs, expanding the scope of the accident; and the ice layer contains impurities that increase the conductivity. These impurities will cause surface flashover, thereby generating high-temperature arcs to burn the insulating material, further destroying the insulation performance, causing serious damage to the equipment and affecting its service life.

[0023] It should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In view of the technical problem that the existing intelligent primary and secondary fusion column-mounted circuit breaker is easy to accumulate snow and affect the service life when installed outdoors, the embodiment of the present disclosure provides an intelligent primary and secondary fusion column-mounted circuit breaker, including a column 1, a circuit breaker body 2, a base 3, and a solar panel 4. The base 3 is fixedly installed on the column 1, the circuit breaker body 2 is fixedly installed on the base 3, the solar panel 4 is fixedly installed on the base 3 through a pillar, and a base plate 5 is slidably installed in the base 3, and the base plate 5 is installed below A first reset body 51 is fixedly installed on the side, a total air inlet channel 31 of a T-shaped structure is opened in the base 3, a fan 32 is fixedly installed in the total air inlet channel 31, and blowing components for blowing air to the circuit breaker body 2 are fixedly installed on the surface of the base 3 at both sides of the circuit breaker body 2, and the blowing components are communicated with the total air inlet channel 31, an air inlet duct 52 is opened in the base plate 5, and a temperature variable body 53 is fixedly installed in the air inlet duct 52. The base plate 5 drives the air inlet duct 52 to overlap with the total air inlet channel 31 through linear movement.

[0025] The solar panel 4 is used to supply power to the fan 32 and the temperature variable body 53. On this basis, the embodiment of the present disclosure can also be connected to an external power source.

[0026] During use, the fan 32 is started to inhale air from the main air inlet channel 31, and then the air is blown toward the surface of the circuit breaker body 2 through the main air inlet channel 31 and the blowing assembly, thereby reducing the temperature of the circuit breaker body 2 during summer use, avoiding the degradation of the insulation performance of the circuit breaker body 2 due to overheating, which is beneficial to extending the service life of the circuit breaker body 2.

[0027] During winter use, snow is easily accumulated on the surface of the circuit breaker body 2. The snow attached to the surface of the circuit breaker body 2 is likely to exert additional pressure on the circuit breaker's casing, bracket and other mechanical parts. Long-term exposure to such additional loads is likely to cause deformation and damage of the parts, affecting the structural stability and normal operation of the equipment. In addition, the snow is easy to freeze and harden. On the one hand, the gaps between the parts become smaller or even frozen, increasing the operating resistance, making the circuit breaker difficult to open and close or even unable to operate normally, resulting in the failure to cut off the circuit in time when a fault occurs, thereby expanding the scope of the accident. On the other hand, the ice layer contains impurities that increase the conductivity. These impurities will cause surface flashover, thereby generating high-temperature arcs to burn the insulating material, further destroying the insulation performance and causing serious damage to the equipment.

[0028] During winter use, when snow accumulates on the surface of the circuit breaker body 2, snow also accumulates on the surface of the substrate 5, so that the weight of the snow accumulated on the surface of the substrate 5 overcomes the resistance of the first reset body 51 and drives the substrate 5 to move downward. In the process of the substrate 5 moving downward, the air inlet duct 52 is driven to overlap with the total air inlet duct 31, so that the air passes through the air inlet duct 52 during the process of moving along the total air inlet duct 31, so that the air is heated by the temperature variable body 53 to form hot air, and then the hot air is blown toward the surface of the circuit breaker body 2 by the blowing assembly to eliminate the snow on the surface of the circuit breaker body 2, so as to prevent the snow from affecting the normal operation of the circuit breaker body 2.

[0029] It should be noted that, in the embodiment of the present disclosure, the weight of the accumulated snow drives the base plate 5 to move so that the air inlet duct 52 and the total air inlet duct 31 overlap, thereby enabling the degree of overlap between the air inlet duct 52 and the total air inlet duct 31 to be controlled by the amount of accumulated snow, thereby enabling part of the air or all of the air to be controlled to contact with the temperature variable body 53 for heating according to the amount of accumulated snow, thereby enabling the snow removal efficiency to be controlled according to the amount of accumulated snow, thereby avoiding excessive blowing of hot air to the circuit breaker body 2 that affects its operation.

[0030] The air inlet duct 52 includes an upper air duct 521 and a lower air duct 522 , and a temperature variable body 53 is fixedly installed between the upper air duct 521 and the lower air duct 522 . Two ends of the temperature variable body 53 penetrate into the upper air duct 521 and the lower air duct 522 , respectively.

[0031] The temperature variable body 53 adopts a semiconductor refrigeration chip in the prior art. The semiconductor refrigeration chip is a very mature technology in the prior art, and the structure, principle and parameters of the semiconductor refrigeration chip are not described in detail here.

[0032] It should be noted that the semiconductor cooling sheet in the prior art can control the temperature of the semiconductor cooling end 531 by controlling voltage, current or pulse width modulation (PWM) technology, and the technology for controlling and adjusting the temperature of the semiconductor cooling end 531 is a very mature technology in the prior art, and the specific control principles and parameters are not described in detail here. The temperature of the cooling end 531 in the embodiment of the present disclosure is 10°-15°.

[0033] The cooling end 531 of the semiconductor cooling sheet penetrates the substrate 5 and enters the lower air duct 522 , and the heating end of the semiconductor cooling sheet penetrates the substrate 5 and enters the upper air duct 521 .

[0034] When used in summer, the base 3 is not compressed, and the first reset body 51 drives the base 3 to be located in the initial position, so that the downwind duct 522 overlaps with the total air inlet channel 31, so that the cooling end 531 of the semiconductor and the downwind duct 522 overlap with the total air inlet channel 31, so that the air can contact the cooling end 531 of the semiconductor refrigeration plate to cool down and form cold air, so that the circuit breaker body 2 can be cooled by blowing cold air, avoiding the circuit breaker body 2 being in a high temperature state in summer when used in summer, resulting in a decrease in insulation performance due to overheating, which is beneficial to extending the service life of the circuit breaker body 2.

[0035] When used in winter, when snow accumulates on the surface of the circuit breaker body 2, the surface of the base body 3 is also covered with snow, so that the weight of the snow drives the base plate 5 to overcome the resistance of the first reset body 51 and move downward, and in the process of the base plate 5 moving downward, the upper air duct 521 and the heating end of the semiconductor refrigeration plate are driven to overlap with the total air inlet channel 31, so that the air is heated by the upper air duct 521 and the heating end of the semiconductor refrigeration plate during the process of moving along the total air inlet channel 31, so that the air is heated by the temperature variable body 53 to form hot air, and then the hot air is blown from the first air outlet toward the surface of the circuit breaker body 2 to eliminate the snow on the surface of the circuit breaker body 2, so as to prevent the snow from affecting the normal operation of the circuit breaker body 2.

[0036] It should be noted that during use, when the accumulated snow drives the base plate 5 to overcome the resistance of the first reset body 51 and move downward, the upper air duct 521 and the lower air duct 522 may overlap with part of the total air inlet channel 31 at the same time, thereby causing the air to contact the two ends of the semiconductor refrigeration plate at the same time. However, due to the low ambient temperature in winter, the temperature of the semiconductor refrigeration end 531 is 10°-15°, which is still higher than the temperature of 0° and below during snowing or melting, and can also play a heating role. That is to say, in winter use, the cooling end 531 of the semiconductor refrigeration plate can also play a slight heating role. Combined with the heating of the heating end 532, it can still play a role in blowing away the snow on the surface of the circuit breaker body 2, thereby preventing the snow from affecting the normal operation of the circuit breaker body 2. Moreover, the situation in which the upper air duct 521 and the lower air duct 522 partially overlap with the total air inlet channel 31 can further improve the effect of controlling part of the air or all of the air to contact with the temperature variable body 53 for heating according to the amount of snow accumulation, thereby further improving the snow removal efficiency according to the amount of snow accumulation and avoiding excessive blowing of hot air to the circuit breaker body 2 to affect operation.

[0037] The base 3 is provided with a receiving groove 34, in which a mounting plate 6 is slidably mounted, a second reset body 61 is fixedly mounted below the mounting plate 6, and the circuit breaker body 2 is fixedly mounted above the mounting plate 6. The circuit breaker body 2 is fixedly mounted above the mounting plate 6 by bolts. After the circuit breaker body 2 is fixedly mounted above the mounting plate 6, the weight of the circuit breaker body 2 presses the mounting plate 6 to overcome the resistance of the second reset body 61 and move downward, so that the base 3 can partially or completely wrap the mechanism box below the circuit breaker body 2, thereby improving the stability of the fixed installation of the circuit breaker body 2. On this basis, the operator can reduce the number of bolts required to fix the circuit breaker body 2, thereby reducing the difficulty of installation and improving the efficiency of installation, thereby facilitating the operator to install, dismantle or perform later maintenance.

[0038] A groove 7 is provided in the base 3 and is located around the mounting plate 6. The groove 7 is used to collect water after snow melts on the surface of the base 3 and the circuit breaker body 2.

[0039] It should be noted that the side wall of the slot body 7 in contact with the circuit breaker body 2 is made of copper or aluminum with high thermal conductivity.

[0040] During use, the concentrated opening of electrical equipment in local areas and the additional load caused by the failure of large industrial equipment will cause the current that the pole-mounted circuit breaker needs to carry to greatly exceed the rated current. The heat generated by the increase in current will increase sharply and easily cause overheating. Local overheating will further cause the degradation of various performances of the circuit breaker body 2, thus creating a vicious cycle that affects the service life.

[0041] It should be noted that the side wall of the slot body 7 is in contact with the circuit breaker body 2 .

[0042] During use, the tank body 7 can store rainwater in summer or water after melting snow in winter. Therefore, when the power consumption suddenly increases and causes the circuit breaker body 2 to suddenly overload and heat up, the side wall of the tank body 7 in contact with the circuit breaker body 2 is cooled by water, and then the temperature of the circuit breaker body 2 during use is reduced through the side wall of the tank body 7, so as to avoid overheating of the circuit breaker body 2 when it is suddenly overloaded and affect its own performance, thereby extending the service life.

[0043] The blowing assembly includes a bidirectional screw 8, a slider 81 and a movable plate 82. The bidirectional screw 8 is fixedly installed in the base 3. The slider 81 is symmetrically installed on the surface of the bidirectional screw 8. The movable plate 82 is fixedly installed on the surface of the slider 81. A driving motor 83 for driving the bidirectional screw 8 to rotate is fixedly installed at the end of the bidirectional screw 8. The bidirectional screw 8 is controlled to rotate by the driving motor 83. A slide groove 33 for accommodating the sliding of the movable plate 82 is opened on the surface of the base 3. A blowing hole 822 is fixedly opened above the movable plate 82. A blowing channel 823 connected to the blowing hole 822 is opened in the movable plate 82. A bellows 824 is fixedly installed on the surface of the movable plate 82. The two ends of the bellows 824 are respectively connected to the blowing channel 823 and the total air inlet channel 31.

[0044] The specific principle and parameters of the driving motor 83 to control the rotation of the bidirectional screw rod 8 belong to the prior art and will not be described in detail here. On this basis, the operator can also drive the bidirectional screw rod 8 to rotate by fixing a crank in the prior art or other manual driving methods to rotate the bidirectional screw rod 8 at the end of the bidirectional screw rod 8.

[0045] During the installation of the circuit breaker body 2, the bidirectional screw rod 8 is driven to rotate by the driving motor 83, thereby driving the bidirectional screw rod 8 to move relatively closer or farther away, so that the movable plate 82 clamps the mechanism box at the lower part of the circuit breaker body 2, thereby further improving the stability of the circuit breaker body 2 during installation.

[0046] The lower part of the movable plate 82 is provided with a protruding clamping portion 821 for clamping the circuit breaker body 2. The protruding clamping portion 821 can ensure that the circuit breaker body 2 is clamped stably.

[0047] When the bidirectional screw rod 8 drives the movable plate 82 to slide in the slide groove 33, the blowing channel 823 in the movable plate 82 is connected with the main air inlet channel 31 through the deformation of the bellows 824, so that the air in the main air inlet channel 31 can be blown from the blowing hole 822 to the surface of the circuit breaker body 2, and then can be blown close to the circuit breaker body 2, thereby improving the blowing cooling or snow removal effect on the circuit breaker body 2.

[0048] The blowing hole 822 is set at an angle with the circuit breaker body 2. The blowing hole 822 set at an angle faces the base 3, so that the circuit breaker body 2 and the surface of the base 3 can be simultaneously removed from the snow in an oblique direction, thereby reducing the snow pressure as a whole. In addition, the movable plates 82 on both sides simultaneously blow and remove snow, so that the air collision can form vortices and turbulence, thereby making the temperature of the circuit breaker body 2 and the surrounding area of ​​the base 3 more uniform, which is conducive to the overall snow removal of the base 3 and the circuit breaker body 2.

[0049] It should be noted that the substrate 5 is located adjacent to the circuit breaker body 2 and as close as possible, so that the snow removal of the substrate 5 is closer to the circuit breaker body 2. Alternatively, the substrate 5 is located close to the edge of the base 3 and as far away from the circuit breaker body 2 as possible, so that when snow is removed from the circuit breaker, the snow on the surface of the base 3 can be removed cleanly, thereby reducing the pressure of the snow.

[0050] It should be noted that the circuit breaker body 2 in the embodiment of the present disclosure can monitor the mechanical and electrical states of the circuit breaker body 2 in real time through sensors and intelligent diagnostic algorithms in the prior art, such as electrical parameters such as current, voltage, power factor, frequency, or mechanical properties such as the degree of wear of contacts, vacuum degree of arc extinguishing chamber, performance of operating mechanism, and insulation resistance, so as to ensure the stable use of the circuit breaker body 2. Intelligent monitoring of the circuit breaker body 2 by sensors is a mature technology in the prior art, and the principle, structure and parameters of intelligent monitoring are not described in detail here.

[0051] Working principle of the embodiment of the present disclosure: When installing the circuit breaker body 2, the circuit breaker body 2 is first quickly fixed on the mounting plate 6 by a small number of bolts, and the weight of the circuit breaker body 2 presses the mounting plate 6 to overcome the resistance of the second reset body 61 and move downward, so that the base 3 can partially or completely wrap the mechanism box below the circuit breaker body 2, thereby improving the stability of the fixed installation of the circuit breaker body 2. Then, the bidirectional screw rod 8 is driven to rotate by the driving motor 83, thereby driving the bidirectional screw rod 8 to move relatively closer or farther, so that the moving plate 82 clamps the mechanism box at the bottom of the circuit breaker body 2, thereby further improving the stability of the circuit breaker body 2 when installed.

[0052] After the installation and clamping are completed, the lower part of the movable plate 82 clamps the circuit breaker body 2, and the fan 32 is started, and the air enters the connected main air inlet channel 31 through the blowing channel 823 and blows toward the circuit breaker body 2 through the blowing hole 822.

[0053] During use, there is no accumulation above the substrate 5 in summer, and the first reset body 51 drives the base 3 to be located in the initial position, so that the downwind duct 522 overlaps with the total air inlet channel 31, and then the cooling end 531 of the semiconductor and the downwind duct 522 overlap with the total air inlet channel 31, so that the air can contact the cooling end 531 of the semiconductor refrigeration plate to cool down and form cold air, so that the circuit breaker body 2 can be cooled by blowing cold air, avoiding the circuit breaker body 2 being in a high temperature state in summer when used in summer, resulting in a decrease in insulation performance due to overheating, which is beneficial to extending the service life of the circuit breaker body 2.

[0054] In winter, when snow accumulates on the surface of the circuit breaker body 2 and the base body 3, the weight of the snow drives the base plate 5 to overcome the resistance of the first reset body 51 and move downward. In the process of the base plate 5 moving downward, the upper air duct 521 and the heating end of the semiconductor cooling plate are driven to overlap with the total air inlet channel 31, so that the air is heated by the upper air duct 521 and the heating end of the semiconductor cooling plate during the process of moving along the total air inlet channel 31, so that the air is heated by the temperature variable body 53 to form hot air, and then the hot air is blown from the blowing hole 822 toward the surface of the circuit breaker body 2 to remove the snow on the surface of the circuit breaker body 2, so as to avoid the snow affecting the normal operation of the circuit breaker body 2. In this way, the overlap between the air inlet duct 52 and the total air inlet channel 31 can be controlled by the amount of snow, and then part of the air or all of the air can be controlled to contact with the temperature variable body 53 for heating according to the amount of snow, and then the snow removal efficiency can be controlled according to the amount of snow, so as to avoid excessive blowing of hot air to the circuit breaker body 2 to affect the operation.

[0055] When electrical equipment in a local area is turned on in a concentrated manner or a large industrial equipment fails, causing the pole-mounted circuit breaker to be overloaded and heated, the tank 7 stores rainwater in summer or water from snowmelt in winter to cool the side walls in contact with the circuit breaker body 2, thereby lowering the temperature of the circuit breaker body 2 during use through the side walls, thereby preventing the circuit breaker body 2 from overheating and affecting its own performance when it is suddenly overloaded, thereby extending its service life.

[0056] Embodiment 2: Based on the above-mentioned embodiment 1, only the differences from embodiment 1 are recorded below.

[0057] An ultrasonic snow depth sensor 54 is fixedly mounted above the substrate 5 , an electromagnet 55 is fixedly mounted inside the base 5 , and an upper magnet 56 is fixedly mounted below the substrate 5 .

[0058] In use, when snow accumulates on the surface of the base plate 5, the ultrasonic snow depth sensor 54 detects the snow accumulation, the semiconductor refrigeration sheet is activated, and the electromagnet 55 is powered on to start adsorbing the upper magnet 56, thereby controlling the base plate 5 to move downward, and switching the connection state between the lower air duct 522 and the main air duct 31 to the connection state between the upper air duct 521 and the main air duct 31. In this way, the upper air duct 521 and the lower air duct 522 in the base plate 5 can be stably switched to each other, which is convenient for use.

[0059] The trough body 7 is provided with a through hole connected to the outside. In the embodiment of the present disclosure, the trough body 7 is only used to collect and discharge water after melting snow or rainwater. When collecting and discharging water after melting snow or rainwater, the water is discharged to the outside through the through hole, thereby avoiding water accumulation on the surface of the base 3 and the circuit breaker body 2, and avoiding damage caused by rainwater corrosion.

[0060] Example 3: Based on the above Example 2, only the differences from Example 1 are recorded below. A temperature sensor 57 is fixedly installed in the base 3 , and the temperature sensor 57 is close to the circuit breaker body 2 and the mounting plate 6 . A connecting hole 58 is provided between the main air inlet duct 31 and the accommodating groove 34 .

[0061] In use, the temperature sensor 57 detects that the temperature of the circuit breaker body 2 is too high, closes the electromagnet 55 and starts the semiconductor cooling sheet, so that the upper air duct 521 is connected with the main air inlet duct 31. The semiconductor cooling sheet works so that cold air enters the connecting hole 58 from the main air inlet duct 31, and then enters the receiving groove 34 from the connecting hole 58 and cools the circuit breaker body 2 in the receiving groove 34. Therefore, when the temperature of the circuit breaker body 2 is too high during use in summer, the circuit breaker body 2 can be cooled in time to avoid overheating of the circuit breaker body 2 and affecting its service life.

[0062] It should be noted that the ultrasonic snow depth sensor 54 and the temperature sensor 57 for controlling the electromagnet 55 and the semiconductor cooling plate belong to the prior art, and the specific circuits and parameters are not described in detail here.

[0063] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and improvements, which are within the scope of the present invention to be protected.
