Embodiment
Please refer to Fig. 1, Fig. 2, the embodiment of the present invention provides a kind of current transformer cooling line, comprising: main pipeline 101; Tube connector 102, comprise hard tube assembly 103 and bellows component 104, the first end of described hard tube assembly 103 is connected with main pipeline 101, the first end of described bellows component 104 is connected with the second end of described hard tube assembly 103, and the second end of described bellows component 104 is used for connecting external equipment 105 or cooling unit 106.
In the present embodiment, main pipeline 101 can connect external equipment 105 by tube connector 102, and external equipment 105 comprises water inlet pipe, outlet pipe, valve etc., and tube connector 102 also can be used as lateral, connects main pipeline 101 and cooling unit 106.Wherein, tube connector 102 is formed by connecting by hard tube assembly 103 and bellows component 104, owing to comprising bellows component 104, therefore, can suitably adjust according to the installation site of external equipment 105 and cooling unit 106 angle of tube connector 102, thereby installation surplus when having promoted greatly each mounting interface docking, increase the degree flexible for installation of cooling line, facilitate the installation of cooling line, in the time that cooling line applies on railway locomotive, also can reduce in railway locomotive running, because the vibration of railway locomotive causes the wearing and tearing of tube connector 102 that the body vibration of cooling line causes and external equipment 105 or cooling unit 106 interfaces.In addition, because tube connector 102 is provided with hard tube assembly 103, and connect main pipeline 101 by hard tube assembly 103, make hard tube assembly 103 form the support for bellows component 104, while avoiding cooling fluid to flow through tube connector 102, cause the gross distortion of tube connector 102, cause tube connector 102 after distortion to touch its other equipment around and affect the problem of other equipment work, the setting of hard tube assembly 103 simultaneously has also increased the intensity of tube connector 102, makes tube connector 102 not fragile.Wherein, hard tube assembly 103 can adopt and be welded to connect with main pipeline 101, and hard tube assembly 103 also can be threaded with the joint employing being arranged on main pipeline 101, and the present invention is not specifically limited this.
In the present embodiment, preferably, bellows component 104 is formed by connecting by bellows piece 107 and hard tube section 108, thus, hard tube section 108 can form and support bellows piece 107, while avoiding cooling fluid to flow through bellows component 104, cause the gross distortion of bellows component 104, cause bellows component 104 after distortion to touch its other equipment around and affect the problem of other equipment work, the setting of hard tube section 108 simultaneously has also increased the intensity of bellows component 104, makes bellows component 104 not fragile.In addition, when the length of bellows component 104 can only comprise bellows piece 107 more in short-term, in the time that the length of bellows component 104 is longer, bellows component 104 can be alternately formed by connecting by multiple bellows pieces 107 and multiple hard tube section 108, and the present invention does not limit the quantity of bellows piece 107 and hard tube section 108 at this.
In the present embodiment, preferred, bellows piece 107 and hard tube section 108 removably connect, thus, situation about being damaged when one section of bellows piece 107 or hard tube section 108, can unload this section of bellows piece 107 or hard tube section 108 to change, easy to operate, save cost.
In the present embodiment, preferably, hard tube assembly 103 is for forming the bend pipe of set angle, wherein, the set angle of bend pipe can be set according to the needed trend of bellows component 104, thereby make hard tube assembly 103 when bellows component 104 is formed to support, bellows component 104 is played to guide effect, ensured that circulating of cooling fluid is smooth and easy in tube connector 102.
In the present embodiment, preferred, the second end of the first end of bellows component 104 and described hard tube assembly 103 removably connects, and the second end of described bellows component 104 is provided with connector, for removably connecting with described external equipment 105 or cooling unit 106.Thus, can make between bellows component 104 and hard tube assembly 103 and bellows component 104 and external equipment 105 or cooling unit 106 between easy installation and removal.
In the present embodiment, hard tube assembly 103 and hard tube section 108 can adopt the hard tube of stainless steel tube or other materials, and main pipeline also can adopt the hard tube of stainless steel tube or other materials, and the present invention does not do concrete restriction to this.
The embodiment of the present invention provides a kind of railway locomotive, comprise car body, in described car body, be provided with current transformer and cooling system for converter, described cooling system for converter comprises arbitrary described current transformer cooling line in cooling unit 106 and claim 1-5, and described tube connector 102 connects external equipment 105 or described cooling unit 106.
In the present embodiment, tube connector 102 is formed by connecting by hard tube assembly 103 and bellows component 104, owing to comprising bellows component 104, therefore, can suitably adjust according to the installation site of external equipment 105 and cooling unit 106 angle of tube connector 102, thereby installation surplus when having promoted greatly each mounting interface docking, increase the degree flexible for installation of cooling line, facilitate the installation of cooling line, also can reduce in railway locomotive running, the tube connector 102 causing due to the body vibration of cooling line and the wearing and tearing of external equipment 105 or cooling unit 106 interfaces.In addition, because tube connector 102 is provided with hard tube assembly 103, and connect main pipeline 101 by hard tube assembly 103, make hard tube assembly 103 form the support for bellows component 104, while avoiding cooling fluid to flow through tube connector 102, cause the gross distortion of tube connector 102, cause tube connector 102 after distortion to touch its other equipment around and affect the problem of other equipment work, the setting of hard tube assembly 103 simultaneously has also increased the intensity of tube connector 102, makes tube connector 102 not fragile.
