Abstract
A novel arc-isolating wall is disclosed to mainly solve the problem that an arc extinguish board in a present arc extinguish chamber is inconvenient to install and replace. The novel arc-isolating wall provided by the utility model is characterized in that an arc-isolating wall body is also provided with several arc extinguish board clamping slots which are positioned on the upper portion of a grid clamping groove; the arc extinguish board clamping slots are rectangular and are arranged parallel to each other; and the arc-isolating wall body is provided with a connecting hole. As the novel arc-isolating wall is provided with the arc extinguish board clamping slots, an arc extinguish chamber with the mechanism provided by the utility can effectively isolate electric arc, and simultaneously installation and replacement of the arc extinguish board are simplified.
Description
Technical field
The utility model relates to a kind of arc separating wall, is specifically related to a kind of novel arc separating wall.
Background technology
Circuit breaker is a kind of existing hand switch effect, can transship automatically again and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; do not start asynchronous motor continually; power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and fault such as under-voltage take place for their, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And behind the disjunction fault current, generally do not need to change parts, therefore obtained to use widely.
It is universal phenomenon that circuit breaker produces arcing, so all be provided with arc control device in the circuit breaker, arc control device are made up of two arc separating walls, arc quenching plate is connected between two arc separating walls, and arc quenching plate top is equipped with arc extinguishing board, has isolated electric arc in all directions, in arc extinguishing, avoided electric arc calcination contact.On October 28th, 2011, Chinese patent discloses a kind of arc control device (patent No. is ZL 201120417273.8), needs repeatedly tighten the screws when the flash barrier in this arc control device is installed, and when a through hole stops up on the flash barrier, need whole replacing flash barrier, install and repair very trouble.
The utility model content
In order to overcome disadvantages of background technology, the utility model provides a kind of novel arc separating wall, has mainly solved the problem that arc extinguishing board is installed in the existing arc control device, replacing is inconvenient.
The technical scheme that the utility model adopts is: a kind of novel arc separating wall, comprise the arc separating wall body, described arc separating wall body is provided with grid sheet draw-in groove, striking sheet draw-in groove, also be provided with some arc extinguishing board draw-in grooves on the described arc separating wall body, described arc extinguishing board draw-in groove is positioned at grid sheet draw-in groove top, described arc extinguishing board draw-in groove is rectangle and is arranged parallel to each other that described grid sheet draw-in groove and arc extinguishing board draw-in groove form certain angle, and described arc separating wall body is provided with connecting hole.
Described grid sheet draw-in groove is rectangle.
Described arc separating wall body edge is provided with radiating groove.
The beneficial effects of the utility model are: this novel arc separating wall is provided with the arc extinguishing board draw-in groove, makes the arc control device that this mechanism has been installed when completely cutting off electric arc effectively, has simplified installation and the replacing of arc extinguishing board.

1-arc separating wall body among the figure, 2-grid sheet draw-in groove, 3-striking sheet draw-in groove, 4-arc extinguishing board draw-in groove, 5-connecting hole, 6-radiating groove.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As Fig. 1 in conjunction with shown in Figure 2, a kind of novel arc separating wall, comprise arc separating wall body 1, described arc separating wall body 1 is provided with grid sheet draw-in groove 2, striking sheet draw-in groove 3, also be provided with some arc extinguishing board draw-in grooves 4 on the described arc separating wall body 1, described arc extinguishing board draw-in groove 4 is positioned at grid sheet draw-in groove 2 tops, and described arc extinguishing board draw-in groove 4 is rectangle and is arranged parallel to each other, described grid sheet draw-in groove 2 forms certain angle with arc extinguishing board draw-in groove 4, and described arc separating wall body 1 is provided with connecting hole 5.Contiguous block 5 is used for the connection of two arc separating wall bodies 1.
Described grid sheet draw-in groove 2 is rectangle.
Described arc separating wall body 1 edge is provided with radiating groove 6.Two arc separating walls piece together, and form a louvre, are used for distributing of the interior heat of arc control device.
The utility model is concrete use as follows: during installation, the arc extinguishing board of the no through hole of a plurality of rectangles and surface is connected between the arc extinguishing board draw-in groove 4 of two arc separating walls, installs arc separating wall and just installed arc extinguishing board; And this structure is not easy to stop up the passage that forms between the flash barrier; Only need change single flash barrier during replacing.
The beneficial effect of utility model is: this novel arc separating wall is provided with the arc extinguishing board draw-in groove, makes the arc control device that this mechanism has been installed when completely cutting off electric arc effectively, has simplified installation and the replacing of arc extinguishing board, has reduced maintenance cost.
