Abstract
The utility model discloses a pressure buffer in a pressure releasing channel of a switch cabinet, which comprises current-limiting chute plates adopting net-shaped structures with small holes, wherein cross sections of the current-limiting chute plates are inverted V-shaped and the small holes are distributed on two sides of the inverted V-shaped cross sections. In the utility model, the current-liming chute plates are improved into the inverted V-shaped ones, a pressure fluid body P in the channel is prevented by the current-limiting chute plates when released out of a channel outlet, a part of pressure fluid bodies L2 and L3 are discharged outside the channel via the small holes on the current-limiting chute plates and gaps between the current-limiting chute plates, and the other part of pressure fluid body L1 is prevented from returning by the current-limiting chute plates, so as to realize buffering by slowing down the releasing speed of the pressure fluid boy P towards the channel outlet and relieving the shock to the channel outlet. The pressure buffer in the pressure releasing channel of the switch cabinet has the advantages of simple structure and convenience in mounting, and is applicable to electric equipment.
Description
Technical field
The utility model relates to power equipment, particularly relates to switch cubicle pressure release passage pressure buffer.
Background technology
Before the utility model proposes, switch cubicle pressure release passage top generally all is to adopt guard, and this guard is narrow meshed network structure, and its function is to satisfy the requirement of degree of protection, prevents that toy from entering in the switch cubicle.When switch cubicle breaks down, can produce great pressure fluid P in the cabinet, at this moment, this pressure fluid P can directly discharge from the aperture of guard along pressure release passage, can cause outer movement of objects of channel outlet and building infringement like this.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, provides a kind of simple and can play the switch cubicle pressure release passage pressure buffer of cushioning effect to the pressure fluid P that fault causes.
In order to realize above purpose, a kind of switch cubicle pressure release passage pressure buffer that the utility model provides, comprise: the band aperture is cancellated current limliting frid, and the cross section of described current limliting frid is down " V " font, and described aperture arrangement is on the dual-side of described " V " font.
In the such scheme, the two ends of described current limliting frid are provided with the extension fixed head, and this extension fixed head is provided with installing hole, and like this, described current limliting frid can be installed on the switch cubicle by this installing hole.
The utility model improves the cross section of current limliting frid and is down " V " font, like this, when channel inner pressure fluid P when channel outlet discharges, can run into the obstruction of current limliting frid, part pressure fluid L2, L3 can be by outside the apertures and the slit passing away between the current limliting frid on the current limliting frid, and another part pressure fluid L1 can be stopped by the current limliting frid and turns back.Pressure fluid P is slowed down to the speed that channel outlet discharges, thereby slow down impact, play the effect of buffering channel outlet.
The utility model is compared with the prior art, and shows that fully its superiority is: simple in structure, easy for installation and can play cushioning effect etc. to the pressure fluid P that fault causes.
Description of drawings
Fig. 1 is an assembly structure schematic diagram of the present utility model;
Fig. 2 is an operation principle schematic diagram of the present utility model.
Among the figure: current limliting frid-1, aperture-2 extends fixed head-3, installing hole-4, switch cubicle-5.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
Present embodiment provides a kind of switch cubicle pressure release passage pressure buffer, comprising: band aperture 2 is cancellated current limliting frid 1, and the cross section of described current limliting frid 1 is down " V " font, and described aperture 2 is arranged on the dual-side of described " V " font.
The two ends of above-mentioned current limliting frid 1 are provided with extends fixed head 3, and this extension fixed head 3 is provided with installing hole 4.
When the utility model uses, choose the radical of current limliting frid 1 earlier according to the model of switch cubicle 5; Then the extension fixed head 3 of current limliting frid 1 by two ends is installed on the switch cubicle 5, and even side by side layout of current limliting frid 1 got final product.In addition, derive as of the present utility model, also can be according to the current limliting frid of the suitable cross section undulate of the model one-shot forming area of switch cubicle 5.
Claims (2)
1. switch cubicle pressure release passage pressure buffer comprises: the band aperture is cancellated current limliting frid, and it is characterized in that: the cross section of described current limliting frid is down " V " font, and described aperture arrangement is on the dual-side of described " V " font.
2. switch cubicle pressure release passage pressure buffer as claimed in claim 1, it is characterized in that: the two ends of described current limliting frid are provided with the extension fixed head, and this extension fixed head is provided with installing hole.
