Description

Technical Field

[0001] The present invention relates to the technical field of intelligent circuit breakers, and specifically to an intelligent circuit breaker with a network communication unit and its usage method. Background Art

[0002] An intelligent circuit breaker, also known as an intelligent low-voltage electrical appliance or power distribution equipment, is an electrical component used to distribute electric energy and control circuits. It has multiple protection functions, such as short-circuit protection, overload protection, etc., and is small in size, light in weight, compact in structure, convenient and flexible to operate, and has high safety performance.

[0003] Although intelligent circuit breakers have many advantages, there are also some disadvantages. For example, the overload protection function of the circuit breaker fails. Generally, the reason for the above problem is incorrect wiring or aging of the wiring of the circuit breaker. When the wiring of the circuit breaker is aged and damaged, it is necessary to touch the contacts of the circuit breaker with a multimeter. If the reading is 0, it means the circuit breaker conducts electricity normally; if the reading is infinite, it means the wire of the circuit breaker has been disconnected and cannot work properly.

[0004] When the overload protection function of the existing circuit breaker fails, it is impossible to quickly detect the cable status of the circuit breaker. At the same time, the existing circuit breakers are all fixed by bolts, which is inconvenient when the staff disassembles the damaged circuit breaker and lacks intelligence. Summary of the Invention

[0029] A method for using an intelligent circuit breaker having a network communication unit comprises the following steps:

[0030] S1: When the multimeter 10 detects that the circuit breaker 7 is damaged, the motor 8 is started through signal transmission. When the motor 8 is started, the power output shaft can drive the rollers 12 to rotate. When the rollers 12 rotate, the pull rope 16 can drive the slider 28 to move upward. When the slider 28 moves upward, the clamping plate 27 contacts the moving block 25, which can drive the connecting block 19 to move upward as a whole.

[0031] S2: When the connecting block 19 moves upward, the linkage plate 22 can be driven to move upward through the cross plate 31. When the linkage plate 22 moves upward, the sleeve 21 can be driven to move upward. When the sleeve 21 moves upward, the plurality of movable balls 32 lose external pressure and become movable. At this time, the staff can take out the damaged circuit breaker 7, place a new circuit breaker on the surface of the bottom plate 1, re-sleeve the wiring tube 37 on the wiring head, and insert the wiring tube 37 into the inner cavity of the fixed tube 33. At this time, the plurality of movable balls 32 can contact the annular diamond groove on the outer side of the wiring tube 37. At the same time, when the moving block 25 continues to move upward and contact the inclined plate 14, it can move forward, break away from the contact with the inclined plate 14 and the clamping plate 27, and move downward.

[0032] S3: When the connecting block 19 moves downward, the horizontal plate 31 can be driven to move downward, and the horizontal plate 31 can drive the sleeve 21 to move downward. When the sleeve 21 moves downward, it can fit with the outer sides of the plurality of movable balls 32, and the cable 11 is fixed.

The connecting rod 43 can drive the cross bar 38 to move upward through the adjacent swing plate 48, thereby lifting the cable 11 upward, further facilitating the staff to remove the damaged circuit breaker 7 and preventing several cables 11 from being entangled.

[0034] Working principle: When the multimeter 10 detects that the circuit breaker 7 is damaged, the motor 8 is started through signal transmission. When the motor 8 is started, the power output shaft can drive the rollers 12 to rotate. When the rollers 12 rotate, the pull rope 16 can drive the slider 28 to move upward. When the slider 28 moves upward, the card plate 27 contacts the moving block 25 to drive the connecting block 19 to move upward as a whole. When the connecting block 19 moves upward, the cross plate 31 can drive the linkage plate 22 to move upward. When the linkage plate 22 moves upward, it can drive the sleeve 21 to move upward. When the sleeve 21 moves upward, the several movable balls 32 lose external pressure and become movable. At this time, the staff can take out the damaged circuit breaker 7, place a new circuit breaker on the surface of the bottom plate 1, re-sleeve the wiring tube 37 on the wiring head, and insert the wiring tube 37 into the fixed tube 3. 3, at this time, several movable balls 32 can contact the annular diamond groove on the outside of the wiring tube 37.

When the connecting block 19 moves downward, it can drive the cross plate 31 to move downward, and the cross plate 31 can drive the sleeve 21 to move downward. When the sleeve 21 moves downward, it can fit with the outside of several movable balls 32. At this time, the cable 11 is fixed. When the damaged cable 11 is turned into an active state, when the electric pole 45 is started, the connecting rod 43 can be pulled upward by the linkage spring 44. The connecting rod 43 can drive the cross bar 38 to move upward through the adjacent swing plate 48, thereby realizing the lifting of the cable 11 upward, further facilitating the staff to take out the damaged circuit breaker 7, and preventing several cables 11 from being entangled.

At this time, the staff can take out the damaged circuit breaker (7), place a new circuit breaker on the surface of the bottom plate (1), re-sleeve the wiring tube (37) on the wiring head, and insert the wiring tube (37) into the inner cavity of the fixed tube (33). At this time, the plurality of movable balls (32) can contact the annular diamond groove on the outer side of the wiring tube (37). At the same time, when the moving block (25) continues to move upward and contact the inclined plate (14), it can move forward, break away from the contact with the inclined plate (14) and the clamping plate (27), and move downward; S3: When the connecting block (19) moves downward, the horizontal plate (31) can be driven to move downward, and the horizontal plate (31) can drive the sleeve (21) to move downward. When the sleeve (21) moves downward, it can fit with the outer sides of the plurality of movable balls (32), and the cable (11) is fixed; S4: When the damaged cable (11) is turned into an active state, when the electric pole (45) is started, the connecting rod (43) can be pulled upward by the linkage spring (44), and the connecting rod (43) can drive the cross bar (38) to move upward through the adjacent swing plate (48), so that the cable (11) is lifted upward, which further facilitates the staff to remove the damaged circuit breaker (7) and prevents the cables (11) from being entangled.
