Abstract
The utility model relates to a section insulator without circuit breakage for a direct current contact system electric section of the electric railway. Four groups of guide plates are fixedly connected to an insulation piece, and two groups of guide plates connecting to two section wires are respectively connected to an adjacent group of guide plates through a continuous current device. When an electric locomotive passes through the section insulator without circuit breakage, the electricity string can not generate between two sections. The section insulator without circuit breakage can ensure safety driving and create advantages for improving the train speed.
Description
The utility model belongs to the improvement of electric railway direct current contact system section point.
The section point majority that present China electric railway direct current contact system is adopted is the epoxy resins insulation circuit sectionalizer, and this kind circuit sectionalizer is connected firmly on insulating part by two groups of ed tabs and constitutes, and two groups of ed tabs are connected with two district's leads respectively.Electric locomotive enters before this device the driver must the manual operation controller power cut-off, slides by manual operation controller energized again behind the circuit sectionalizer, and locomotive continues to be subjected to popular sailing, and road speed is restricted.Press operating regulations, forbid locomotive charged, so driver's spirit must high concentration during at every turn by electric segmentation place in electric locomotive, and carelessness is arranged slightly, does not have power cut-off that charged accident by the insulation circuit sectionalizer will take place by electric segmentation place.According to the introduction of Chinese patent application 87.2.07246 specification sheets, the electric section insulator of water chestnut row solved electric locomotive by the time problem of manual operation controller power cut-off not, and guarantee that locomotive is subjected to stream uninterrupted, but this device locomotive by the time moment of two sections of short circuit arranged.When section interruption maintenance of contact system, once there is electric locomotive to pass through this device, will be at transcient short circuit time fax to the power failure operating area, jeopardize the personal safety of power failure operating area.Introduce according to another Chinese patent application 87.2.11300 specification sheets, interrupted deflecting plate neutral section insulator also solved electric locomotive by the time problem of manual operation controller power cut-off not, but there is the cutout problem in this device, and road speed is restricted.
The invention the purpose of this utility model is to make a kind ofly to continue to flow when utilizing deflecting plate and afterflow device to guarantee electric locomotive by electric segmentation place, and make two sections not have short circuit phenomenon, thereby allow the driver not make any M/C, locomotive just can be by the insulation circuit sectionalizer of electric segmentation place.
Characteristics of the present utility model are that the two groups of deflecting plates and the middle two groups of deflecting plates that link to each other with contact system two district's leads respectively connect firmly equally on insulating part, and the two piece lead-in wire connections of two groups of deflecting plates by afterflow device are faced at two ends mutually.
The utility model has the advantages that the shortcoming that has overcome water chestnut electric section insulator of row and interrupted deflecting plate neutral section insulator.Utilize afterflow device by deflecting plate to powering continuously by locomotive, and do not make two sections that short circuit phenomenon is arranged, guaranteed traffic safety, created advantage for improving road speed.
Fig. 1 is the front elevation that continuous electrical isolation circuit sectionalizer is suspended on segmentation place of contact system electricity.
Insulation circuit sectionalizer (7) be connected (A) district and (B) distinguish between, main element is that afterflow device (3), (3 ') of diode are suspended on the catenary (1) by dropper (4), (4 '), be connected with insulation circuit sectionalizer (7) by lead (5), (5 '), insulation circuit sectionalizer (7) is suspended on the catenary (1) by dropper (6), installing four insulation rods (2) between three droppers (4) of catenary (1), (4 '), (6).
Fig. 2 is the birds-eye view of insulation circuit sectionalizer (7).Deflecting plate (8), (10), (11), (8 ') connect firmly on insulating part (9), and deflecting plate (8), (8 ') are connected with (A), (B) two district's leads respectively.
The utility model is made simple, easy to use, insulation circuit sectionalizer (7) is suspended on the catenary (1) by dropper (6), two ends deflecting plate (8), (8 ') respectively and (A), (B) two district's leads connect, when electric locomotive marches to the insulation circuit sectionalizer by (A) district, pantograph leaves that deflecting plate (8) is preceding just to be contacted with deflecting plate (10), after leaving deflecting plate (8), under the effect of afterflow device (3), continue to be flowed by deflecting plate (10), deflecting plate (10) is preceding just to be contacted with deflecting plate (11) when pantograph is left, in afterflow device (3), under the effect of (3 ') simultaneously from deflecting plate (10), (11) accept (A), (B) district's electric current; After pantograph is left deflecting plate (10), under the effect of afterflow device (3 '), accept (B) district electric current from deflecting plate (11); Deflecting plate (11) is preceding just to be contacted with deflecting plate (8 ') when pantograph is left, and (B) district electric current is directly accepted in beginning.Effect when entering (A) Qu Shitong (A) district from (B) district and entering (B) district is identical.
