Problems solved by technology

[0003] If the structure of the nozzle is unreasonable, the operation work of the mechanism will be seriously wasted, the operation impact will be increased, and the reliability of the switch will be reduced.
It may even lead to the failure of breaking and cause the explosion of the load switch or the inflatable cabinet, causing serious consequences
[0004] The nozzle of the load switch in the prior art usually has only one gas channel. When the rotary piston is compressed, the gas in the cylinder can only flow from one channel, such as the channel between the two contact blades of the movable contact blade. It reaches the arc extinguishing chamber, so its arc extinguishing ability is not strong, the arc cannot be controlled at the most favorable position for arc extinguishing, and the arc cannot be extinguished at the fastest speed

[0035] Such as Figure 5 As shown, in the rotary compressed air load switch of the first embodiment of the present invention, the rotary piston 100 of the arc extinguishing chamber is fitted on the moving contact knife (or called the moving contact) 200, and the moving contact knife 200 is installed on the lower static contact 22, The rotary piston 100 is equipped with a cylinder 27 . When the rotary pneumatic load switch of the embodiment of the present invention is opened, that is, the combination of the rotary piston 100 and the movable contact blade 200 is in the cylinder 27, away from the upper static contact 21 from the position connected to the upper static contact. When the direction of the head 21 is rotated, the rotary piston 100 compresses the gas in the cylinder 27 .

[0036] In the nozzle assembly of the first embodiment of the present invention, the technical solution adopted is that the air outlet 10 of the nozzle assembly is arranged on the rotary piston 100 o...

[0046] The parts of this embodiment that are the same as those of the first embodiment will not be repeated here.

[0047] Such as Figure 6-Figure 8 As shown, the difference between this embodiment and the first embodiment is that in this embodiment, only the main nozzle 12 and the first side nozzle 11 are provided, instead of the second side nozzle. Correspondingly, the air outlet 10 has the first One side 101 and the second side 104, the difference between the second side 104 of this embodiment and the second side 102 in the first embodiment is that the second side 104 is no longer vertically arranged, and It has a certain inclination. In this embodiment, the gas passes through the main nozzle 12 and the first side nozzle 11 to extinguish the arc, so an arc striking device can be installed on the first blade 201 to guide the arc to the side of the first blade 201 .

[0050] The parts of this embodiment that are the same as those of the first embodiment will not be repeated here.

[0051] Such as Figure 9 with Figure 10 As shown, the difference between this embodiment and the first embodiment is that in this embodiment, only the main nozzle 12 and the second side nozzle 13 are provided, instead of the first side nozzle. Correspondingly, the air outlet 10 has the second side nozzle One side 109 and the second side 102, the difference between the first side 109 of this embodiment and the first side 101 in the first embodiment is that the first side 101 is no longer vertically arranged, and It has a certain inclination. In this embodiment, the gas passes through the main nozzle 12 and the second side nozzle 13 to extinguish the arc, so an arc striking device can be provided on the second blade 202 to lead the arc to the side of the second blade 202 .

Abstract

The invention discloses a rotary air-compressing load switch and a nozzle assembly thereof. The nozzle assembly comprises a rotary piston installed in a cylinder and a movable contact knife. The top of the rotary piston is inwardly recessed to form an air outlet corresponding to the cylinder. The air outlet is provided with a first lateral side and a second lateral side. The movable contact knife corresponds to the cylinder, is fixedly connected with the inner side of the rotary piston, and comprises a first blade and a second blade in parallel. Gaps are arranged between the first blade and the second blade, the first lateral side and the first blade and / or the second blade and the second lateral side such that a main nozzle, a first lateral nozzle and / or a second lateral nozzle are formed. Therefore, when the rotary piston rotationally compresses air in the cylinder, the air fast erupts from the air outlet via the nozzles. The nozzle assembly may control arc at a position which is the most beneficial to arc extinction and extinguishes the arc at the highest speed.

Description

technical field [0001] The invention relates to the technical field of switching appliances, in particular to a spout assembly and a rotary compressed air load switch with the spout assembly. Background technique [0002] The nozzle assembly of the rotary compressed air load switch is the core component of the arc extinguishing chamber. Its structure is closely related to the arc extinguishing ability of the load switch. A reasonable nozzle structure can control the arc at the most favorable position for arc extinguishing and extinguish it at the fastest speed. arc, improve the breaking performance of the load switch, and reduce the operating work of the mechanism. [0003] If the structure of the nozzle is unreasonable, the operation work of the mechanism will be seriously wasted, the operation impact will be increased, and the reliability of the switch will be reduced. It may even lead to the failure of breaking and the explosion of the load switch or the inflatable cabin...
