Description
Technical field
It the utility model is related to a kind of breaker, more particularly to a kind of frame-type circuit breaker.
Background technology
With the development of science and technology breaker is widely used, frame-type circuit breaker is one in breaker application
Kind more typical breaker structure, also known as omnipotent breaker, it is that one kind can be connected, carried and disjunction normal circuit bar
Electric current under part, one kind machinery of certain time and breaking current can be also connected, carried under defined improper circuit condition
Device for switching；And in frame segment pantograph disconnecting switch, its bottom housing section is made up of pedestal and bottom plate two parts, and assembling is fixed between the two
Position is bad, situation about misplacing easily occurs, influences efficiency of assembling.
The content of the invention
The utility model is solution the deficiencies in the prior art, there is provided one kind assembling is well-located, and is not easy out
A kind of frame-type circuit breaker now to misplace.
To achieve the above object, the utility model employs a kind of frame-type circuit breaker, including mask, conducting system, touches
Head system, arc-control device, operating mechanism and drain pan, drain pan include pedestal and bottom plate, and both pedestal and bottom plate coordinate its internal shape
Into 4 cavitys, cavity use is transversely arranged on the inside of drain pan side by side, and is isolated between adjacent cavities by border；At pedestal
Respectively close to being provided with boss on the border of the cavity of outside two, and used between boss and angie type is arranged；At the bottom plate and base
Shrinkage pool is provided with seat boss mated position, and gap is formed between the boss and shrinkage pool and is coordinated；Each side on the pedestal
Spacing batten is provided with boundary, and the spacing batten is arranged on border to opening position, bottom plate between the boss of angie type arrangement
Place forms spacing gap with each borderline spacing batten at pedestal by the limited impression which is provided with and coordinated.
Said frame formula breaker, coordinate because pedestal and bottom plate are formed in the frame-type circuit breaker, if being internally formed
A dry cavity, by contour connection between adjacent cavities, but the main effect in the border be by pedestal and bottom plate respectively
The border being provided with, which is formed, to be coordinated, and makes upper and lower borderless contact, and the cavity close to boundaries on either side is respectively formed closed form；Thus
Stopping means can be set at cavity boundary, and during due in most cases installing drain pan, used mode is first to drain pan
Surrounding can fixed position be fixed, after to remaining part operate；Thus stopping means is set in the boundary of outermost two, then
Person its due to setting stopping means unsuitable too small on border, otherwise can influence your intensity, and stopping means can be installed on border
Place is more than below, then can install one or more stopping means at top, and a stopping means is only installed at lower section, furthermore
Because the stopping means should not be excessive, otherwise it is not easy to pedestal and is closed with base, thus limit is set at outer boundaries diagonal position
Position device；It is spacing between pedestal and bottom plate to strengthen, can also in the spacing batten that each cavity boundary middle position is set with
Limited impression be respectively cooperating with forming it is spacing between pedestal and bottom plate, by between stopping means, spacing batten and limited impression
Cooperation, form spacing between pedestal and bottom plate, this is spacing reliable, and installation place is less prone to the situation of dislocation.
The utility model is further arranged to, and first boss and the 3rd are provided with its top position of left border at pedestal
Boss, and relative to being provided with second boss at first boss and the 3rd boss diagonal position；Left border is below at bottom plate
Opening position is provided with the first shrinkage pool and the 3rd shrinkage pool, is formed at bottom plate right side boundary and with first shrinkage pool and the 3rd shrinkage pool diagonal
The opening position of arrangement is provided with the second shrinkage pool；Each boss and shrinkage pool at pedestal and bottom plate, set using with contract position,
The gap limit being made up of each boss in said base and bottom plate, shrinkage pool between pedestal and bottom plate coordinates.
Said frame formula breaker, the boss and groove by being provided with pedestal and bottom plate, form pedestal and bottom
Plate is spacing, also relatively reasonable due to setting two stopping means because settable spacing place is more than lower section above border, furthermore
By spacing between the cooperation composition pedestal and bottom plate of stopping means, this scheme is first scheme.
The utility model is further arranged to, and first boss, and phase are provided with its top position of left border at pedestal
For being provided with second boss at first boss diagonal position；To be provided with first recessed for opening position below for left border at bottom plate
Hole, at bottom plate right side boundary and form the opening position diagonally arranged with first shrinkage pool and be provided with the second shrinkage pool；Pedestal and bottom plate
Each boss and shrinkage pool in place, set using with contract position, pass through each boss in said base and bottom plate, shrinkage pool structure
Coordinate into the gap limit between pedestal and bottom plate.
Said frame formula breaker, it is described to be respectively adopted two relative to the scheme used in such scheme for border top
Boss and groove, composition is spacing, but is unlikely to the situation of dislocation cooperation in view of coordinating, but the probability phase that this situation occurs
To relatively low, thus to ensure the efficiency of product installation, set a boss to be formed with groove above border spacing, be preferred option.
The utility model is further arranged to, and its cross section of the boss being provided with pedestal is the conical surface, and the boss bottom hole
Footpath is more than top aperture.
Said frame formula breaker, described is to consider production efficiency, efficiency of assembling, boss will be coordinated to be arranged to the conical surface, can
Certain efficiency of assembling is improved, this is rational in infrastructure, and usability is produced in batches in product.
The utility model is further arranged to, and its cross section of the boss being provided with pedestal is to face directly.
Using cone match, then not said frame formula breaker, the fit system employed in the aforesaid way are
With in the case of not, the required effect that reaches is different, to meet the needs of different clients, using face directly form coordinate and
Need existing.
