Description
Technical field
The utility model is related to frame for movement technical field more particularly to a kind of insulation of railcar dc circuit breaker are outer
Shell.
Background technology
With the continuous development of railcar, vehicle is more next to safe operation, the requirement of installation maintenance of dc circuit breaker
It is higher.Currently, existing dc circuit breaker is installed on mostly in the frame of metal welding, the direct current that this mounting means requires is disconnected
Apart from bigger, the installation space size of corresponding breaker will increase the electrical safety on road device and ground, be unfavorable for the small of product
Type and lightweight.
Utility model content
The purpose of this utility model is to provide a kind of railcar dc circuit breaker insulation crust, simple in structure, reliable
Property it is strong, be easily installed.
The purpose of this utility model is achieved through the following technical solutions：
A kind of railcar dc circuit breaker insulation crust is installed on car body for fixing dc circuit breaker, including
Lower housing 1, sealing ring 2 and upper shell 6；Sealing ring 2 is set to the junction of lower housing 1 and upper shell 6,
1 side of lower housing is equipped with connector mounting hole 3, peep hole 4 and cable aperture 5.
The lower housing 1 sets that there are four mounting holes 7 with upper shell 6.
The lower housing 1 is formed with upper shell 6 by glass fiber reinforced unsaturated polyester plastic pressure injection.
The sealing ring 2 is made of high-temperature silicon disulfide rubber.
6 bottom of upper shell is embedded in four M8 screw holes.
A kind of subway that the utility model embodiment provides it can be seen from above-mentioned technical solution provided by the utility model
Vehicle DC breaker insulation crust, it is simple in structure, highly reliable, be easily installed.Breaker installation space is reduced, is improved
The shock resistance of dc circuit breaker and vibration ability, the reliability for simplifying composed structure, enhancing device are reduced and are produced into
Sheet and maintenance cost.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
The attached drawing used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some implementations of the utility model
Example, for those of ordinary skill in the art for, without creative efforts, can also be according to these attached drawings
Obtain other accompanying drawings.
Fig. 1 is the structural schematic diagram for the railcar dc circuit breaker insulation crust that the utility model embodiment provides；
Fig. 2 is that the lower housing structure for the railcar dc circuit breaker insulation crust that the utility model embodiment provides is shown
It is intended to；
Fig. 3 is that the upper shell structure for the railcar dc circuit breaker insulation crust that the utility model embodiment provides is shown
It is intended to.
Specific implementation mode
With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, belongs to the scope of protection of the utility model.
The utility model embodiment is described in further detail below in conjunction with attached drawing.
Embodiment one
As shown in Fig. 1 to Fig. 3, a kind of railcar dc circuit breaker insulation crust is pacified for fixing dc circuit breaker
Loaded on car body, including lower housing 1, sealing ring 2 and upper shell 6；Sealing ring 2 is set to the junction of lower housing 1 and upper shell 6；
Rainwater can be better protected to enter in shell.Degree of protection IP67 is widely used in high altitude localities and other severe rings
It is run steadily in the long term under border.Sealing ring 2 is made of high-temperature silicon disulfide rubber, and high-temperature silicon disulfide rubber is the line with high molecular weight
Property poly dimethyl (or methyl ethylene, methyl phenyl vinyl, methyl trifluoro propyl etc.) siloxanes be basic polymer, be mixed into
Reinforced filling and vulcanizing agent (organosilicon oxide) etc., in the lower vulcanization elastomer-forming of heating, pressurization.
In this example, 1 side of lower housing is equipped with connector mounting hole 3, peep hole 4 and cable aperture 5.The connection
Device mounting hole 3 for fixing low voltage connector, come control breaker separating brake and combined floodgate and feedback signal transmission.Described
Whether peep hole 4 is normal for checking breaker closing and disconnection, convenient for safeguarding.The cable aperture 5 is used for extraneous high-voltage electricity
Cable connects.
In this example, the lower housing 1 and upper shell 6 set that there are four mounting holes 7.Specifically, surrounding is stayed, there are four diameters
The mounting hole 7 of 10mm, it is convenient to be installed with metro vehicle car body.
In this example, the lower housing 1 is formed with upper shell 6 by glass fiber reinforced unsaturated polyester plastic pressure injection.
It is resistance to filthy and moist, it is suitable for severe cold areas and filthy serious area.Glass fiber reinforced unsaturated polyester plastic SMC is
The english abbreviation of sheet, molding, compound, i.e. sheet molding compound.Primary raw material by SMC special yarns, unsaturated-resin,
Shrinking agent, filler and various auxiliary agents composition.
In this example, 6 bottom of upper shell is embedded in four M8 screw holes.Facilitate fixed dc circuit breaker.
As it can be seen that the utility model embodiment is mounted on inside by insulation crust structure, by dc circuit breaker, to simplify
Composed structure, the reliability for enhancing device；It reduces production cost, the weight and volume for reducing device, facilitate peace
Dress and use.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
Subject to the scope of protection of the claims.
