Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a backup protector with a fast circuit breaking protection function. Background Art

[0002] Backup protection refers to the protection used to cut off the fault when the main protection or circuit breaker fails to operate. When a circuit fails, the protection on the circuit will instantly send a signal to disconnect the circuit's breaking element. This immediate protection is the main protection. When the main protection does not operate for various reasons, after a short delay, another protection will start and operate to trip the fault circuit. This protection is the backup protection.

[0003] However, the existing backup protector has the following problems during use: since the backup protector is a backup protection device that will only be triggered when the circuit breaker refuses to operate, the backup protector is idle for a long time, rusts or ages excessively, and the gate body is blocked, resulting in failure to trip normally, and lacks corresponding maintenance means. Therefore, it is necessary to design a corresponding technical solution to solve the existing technical problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides a technical solution: a backup protector with a fast circuit breaker protection function, comprising a protector body 1 and a gate assembly mounted on the protector body 1, the gate assembly comprising a hollow shaft 2, an oil guide rod 3, a rotor 4, an inner ring 5 and an insulating gate 6, the hollow shaft 2 is mounted on the protector body 1 and has a flow guide cavity 7 formed inside, the oil guide rod 3 is divided into several groups and is evenly distributed in the hollow shaft 2 in a ring shape, the oil guide rod 3 comprises an arc-shaped liquid accumulation plate 8 and two groups of blades 9 symmetrically mounted on the outer side of the arc-shaped liquid accumulation plate 8, the bottom of the arc-shaped liquid accumulation plate 8 The main body has a hollow structure, two groups of blades 9 are symmetrically inserted on the hollow shaft body 2 and a drainage hole 10 is formed between them, the rotor 4 is divided into several groups, and the several groups of rotors 4 are evenly distributed between the hollow shaft body 2 and the inner ring 5, the inner ring 5 is fixed on the inner wall of the insulating gate 6, and a maintenance and lubrication component is also installed on the outer end of the hollow shaft body 2. The maintenance and lubrication component includes a cover body 12 with a liquid accumulation groove 11 formed inside and an airbag ball 13 installed on the cover body 12. An oil inlet pipe 14 is installed on the top of the cover body 12 and a drainage port 15 is opened in the lower left corner. The drainage port 15 is connected to the guide cavity 7.

[0020] Further improvement, such as Figure 3 As shown, the bottom of the cover body 12 is processed into an inclined structure and the height of one end close to the drain port 15 is smaller than the height of the other end. This design makes it easy to discharge the internal lubricating liquid through the drain port 15.

[0021] Further improvement, such as Figure 3 As shown: the airbag ball 13 is a two-stage structure and includes a pressing hemisphere 16, a partition 17 and a telescopic hemisphere 18. The pressing hemisphere 16 is filled with gas, and the partition 17 is located between the pressing hemisphere 16 and the telescopic hemisphere 18. The telescopic hemisphere 18 is built into the liquid accumulation groove 11. By applying pressure to the pressing hemisphere 16, the internal gas can be introduced into the telescopic hemisphere 18, so that the telescopic hemisphere 18 expands and the internal lubricating fluid is guided outward.

[0022] Further improvement, such as Figure 3 As shown, a gas guide port 19 is opened in the middle of the partition 17 , and both ends of the gas guide port 19 are respectively connected to the pressing hemisphere 16 and the telescopic hemisphere 18 , so as to facilitate the gas to be guided through the gas guide port 19 .

[0023] Specifically, the telescopic hemisphere 18 is in a hemispherical structure as a whole and has a layered structure formed on the surface. This design makes it easy to inflate and deflate the telescopic hemisphere 18.

[0024] During use: When the brake body of the backup protector of the utility model is aged, rusted, etc., the staff can introduce the lubricating liquid from the oil inlet pipe 14 and into the liquid accumulation tank 11, and then block the oil inlet pipe 14. At this time, the internal gas can be introduced into the telescopic hemisphere 18 by pressing the hemisphere 16, so that the telescopic hemisphere 18 expands and quickly squeezes out the internal lubricating liquid. The lubricating liquid flows along the guide cavity 7 and sprays the oil onto the rotor 4 through the oil guide rod 3, so as to achieve the purpose of lubricating the hollow shaft 2 and the inner ring 5.
