[0031] Example 2
[0032] On the basis of the embodiment 1, the scheme in the embodiment 1 is further refined in combination with the specific working mode as follows: Figures 1 to 8
[0033] As a preferred embodiment, the inner cavity of the limiting adjusting frame 7 leaves space for the rotation rod 9 to move, and the two sets of limiting adjusting frames 7 are symmetrically arranged; further, the two sets of limiting adjusting frames 7 are symmetrically arranged, so that the rotation rod 9 is uniformly stressed on both sides during movement, and this symmetrical support structure can effectively prevent the rotation rod 9 from deviating or shaking during adjustment, thereby ensuring that the adjusting mounting plate 11 can be angle-adjusted in a stable state. When the circuit breaker needs to be installed in a switch cabinet with a certain inclination angle, the symmetrical limiting adjusting frames 7 can make the rotation rod 9 rotate smoothly, and then the adjusting mounting plate 11 can be accurately adjusted to the required angle.
[0034] As a preferred embodiment, the rotation rod 9 is inserted into the inner cavity of the two sets of movable holes 8 and abuts against the limiting shaft 10 to realize spot welding, the limiting shaft 10 is larger than the inner diameter of the movable hole 8, and the outer surfaces of the two ends of the rotation rod 9 respectively abut against the inner surfaces of the two sets of movable holes 8; further, since the rotation rod 9 abuts against the inner surface of the movable hole 8 and is axially limited by the limiting shaft 10, the rotation angle of the rotation rod 9 can be accurately controlled during rotation adjustment, and the operator can make fine adjustment in small angle increments according to actual installation requirements. This precise control can meet the complex installation space and angle requirements inside different switch cabinets.
[0035] As a preferred embodiment, the rotation adjusting mounting plate 11 changes the angle of the rotation rod 9, so that the rotation rod 9 rotates along the inner surface of the two sets of movable holes 8 around its axis; further, the angle of the rotation rod 9 is changed by the rotation adjusting mounting plate 11, so that the installation angle of the entire circuit breaker can be adjusted as needed, which greatly enhances the adaptability of the circuit breaker in different installation environments. With this rotation adjustment function, the circuit breaker can be easily installed at the appropriate angle.
[0036] As a preferred embodiment, the eight sets of bolts 15 are symmetrically arranged, and the eight sets of bolts 15 are inserted into the inner cavity of the mounting hole 14 and engaged with the bottom of the mounting base 6; further, the eight sets of bolts 15 are symmetrically arranged, so that the mounting base 6 can evenly disperse the force when connected to the external installation plane, and the force is evenly transmitted to the installation plane through the symmetrically arranged bolts 15.
[0037] As a preferred embodiment, the heat dissipation holes 5 are arranged in several groups, and the several groups of heat dissipation holes 5 are arranged in an equidistant interval manner; further, hot air naturally rises due to its small density, and is discharged to the external environment through the equidistantly arranged heat dissipation holes 5.
[0038] The working process of the utility model is as follows: firstly, the liquid crystal display 3 on the control panel 2 displays the working state of the circuit breaker in real time during the operation process, including the information of the opening, closing, energy storage state and various electrical parameters, which is convenient for the operator to understand the equipment operation at any time, the vacuum arc extinguishing chamber 4 is responsible for cutting off and connecting the circuit during the opening and closing operation, and the high insulation performance and arc extinguishing capacity of the vacuum environment are used to ensure the reliable opening and closing of the circuit, avoid damage to the equipment by arc and ensure the safe and stable operation of the power system;
[0039] When the circuit breaker needs to be installed, the installer first rotates the angle of the two sets of adjusting installation plates 11 according to the actual layout and space requirements of the switch cabinet or the installation site, since the rotating rod 9 is in close abutment with the inner surface of the movable hole 8 and is axially limited by the limiting shaft 10, the adjusting installation plate 11 can be fixed on the equipment cabinet by the fixing member such as screw in the installation cavity 12, lifting or lowering one of the two sets of adjusting installation plates 11 will make the rotating rod 9 rotate smoothly along the inner surface of the two sets of movable holes 8 around its axis, so as to accurately adjust the installation angle, the two sets of symmetrically arranged limiting adjusting frames 7 provide stable support for the rotating rod 9, ensure that the rotating rod 9 is uniformly stressed and does not deviate during the adjusting process, ensure that the circuit breaker body 1 can be adjusted to the most suitable installation angle, so as to realize precise butt joint and cooperation with the surrounding electrical equipment, the eight sets of symmetrically arranged bolts 15 are inserted into the eight sets of installation holes 14 and are engaged and connected with the bottom of the installation base 6 through the four sets of connecting plates 13, so as to firmly fix the limiting adjusting frame 7 on the installation plane, so that the whole circuit breaker can remain stable during the operation process and will not be displaced or loosened due to factors such as vibration and external impact, a plurality of groups of evenly distributed heat dissipation holes 5 play an important role, the heat generated by the electronic elements in the control panel 2 during work will cause the temperature of the surrounding air to rise, the hot air will naturally rise due to its small density, and is discharged to the external environment through the equidistantly spaced heat dissipation holes 5, and the connecting plug 16 facilitates the quick connection and disconnection of the circuit breaker with the external control line and communication line, the above is the working principle of the liquid crystal display intelligent indoor vacuum circuit breaker.
