Description
Technical field
The utility model is related to the apparatus field of current conversion station/transformer station of 220kV and above, more specifically
Say, be related to the shell for disconnecting switch module.
Background technology
Disconnecting switch (is commonly called as " disconnecting link "), the generally referred to as isolation of high voltage isolator, i.e. rated voltage in more than 1kV
Switch, often referred to simply as disconnecting switch, be in high-voltage switch electric appliance using a kind of most electrical equipment, the operation principle of itself and
It is relatively simple for structure, but be due to that usage amount is big, functional reliability requires high, to electric substation, the design of power plant, sets up and safety
The influence of operation is larger.Disconnecting switch is mainly characterized by no arc extinguishing ability, can only divide in the case of no load current,
Close circuit.Disconnecting switch is used for each step voltage, and as changing circuit connection or making circuit or equipment and isolated from power, it does not break
Stream ability, is operated again after can only first circuit be disconnected with miscellaneous equipment.The general connection with maloperation when preventing from switching on-load
Locking device, it is sometimes desirable to which pin switchs to prevent from disconnecting under the magneticaction of big failure.
But the development of the progress and national economy with power technology, GIS products are commercially accounted for by self structure
Ground area is small, and operation troubles rate is low, lightweight, non-maintaining etc., and a series of advantages are more and more applied.
The single break disconnecting switch module (DS used on traditional GIS：Disconnector Switch) will not fit into
The demand of present industrial.By the disconnecting switch module of mechanical communication because its outstanding stability has obtained the concern and again in market
Depending on, but because the metallic produced by mechanical transmission course can influence the uniformity of internal electric field, there is switch module
Potential safety hazard.
Utility model content
The utility model aim to provide it is a kind of be avoided that metallic influence internal electric field, safe and reliable one kind keeps apart
Close module housing.
In order to solve the above-mentioned technical problem, the utility model proposes technical scheme it is as follows：
For the shell of disconnecting switch module, including outer cover body, the inside of outer cover body is N number of, and being used for of being sequentially communicated holds
The cavity of a set of disconnecting switch is put, at least one particle trap is provided with the inwall bottom surface of cavity；Shell body bottom portion and with
Particle trap homonymy is provided with N number of correspondence and connects the shield shell of each cavity, is used in shell outer body provided with least one
In the peep hole of observation cavity.
Multiple disconnecting switch modules are can be set in multiple cavities connection, it is adaptable to which plurality of devices is switched.Particle trap is set up to adopt
Collection metallic simultaneously makes the granule trap keep electric field ground potential by shield shell, and the metallic for so entering trap will not
Again fly ease to escape from.
As the improvement of scheme one, particle trap is infundibulate blind hole, and big end opening is towards cavity.
As the improvement of scheme one, the opposite sides of cavity is equipped with a pair of the through holes turned on for disconnecting switch, one
To being all covered with the first disc insulator on through hole.
As the improvement of scheme one, explosion-proof apparatus is provided with away from the side of outer cover body in shield shell.
As the improvement of scheme one, the junction of shield shell and outer cover body is covered with the second disc insulator,
Two disc insulators are provided with towards the side of cavity to be used to support the support base for installing disconnecting switch.
As the improvement of scheme one, in addition to grounding switch, the peace for being used for installing grounding switch is provided with the top of cavity
Fill hole.
As the improvement of scheme one, outer cover body is molded by integral cast, and material is aluminium alloy ZL101A-T6.
The utility model has the advantages that：
1. effectively preventing influence of the metallic to internal electric field, make switch module operation safe and reliable.
2. further metallic is controlled, it is to avoid it enters cavity once again influences internal electric field.
3. being molded by integral cast, good airproof performance is sturdy and durable.

Embodiment
Embodiment
As shown in Figure 1 to Figure 3, the shell for disconnecting switch module, including outer cover body 1, the inside of outer cover body 1 is set
There are three cavitys 2 for being used to house a set of disconnecting switch (not depending on going out) being sequentially communicated, two are provided with the inwall bottom surface of cavity 2
Particle trap 3；Three shielding cases that are corresponding and connecting each cavity 2 are provided with the bottom of outer cover body 1 and with the homonymy of particle trap 3
Body 4, shield shell 4 is pipe fitting and is located between two particle trap 3, is used to observe cavity 2 provided with two in the outside of outer cover body 1
Peep hole 5.The opposite sides of cavity 2 is equipped with a pair of the through holes 6 turned on for disconnecting switch, is covered on a pair of through holes 6
