Description
Technical field
The present invention relates to the electric railway section post, particularly a kind of multiple line of electrified railway section post main electrical scheme with the capacitive character electrical equipment.
Background technology
The multiple line electrified railway is provided with section post at the feeding section end usually.The electrical main connecting wire of conventional section post only comprises Switch equipment, can with connection feeding section the up-downgoing contact system by Switch equipment carry out the up-downgoing parallel connection, the switch of more distinguishing that arranges between by two adjacent feeding sections when a traction substation is out of service carries out over zone feeding.
The section post parallel operation can reduce traction net equivalent impedance, improves the traction power supply ability; Improve traction net current distribution, reduce loaded vehicle direction traction net current capacity demand, its improvement degree is directly proportional with the gap of up-downgoing train electric current, and gap is larger, improves effect better; Reduce traction net energy loss.
Conventional contact system current capacity is 800A approximately.Mountain area electrified railway long steep grade is more, and the gradient is up to 18 ‰, 24 ‰ even 30 ‰, and electric current is very large for heavily loaded direction (upward slope direction), and underloading direction (direction of fall) electric current is very little.Take railways in Southwestern area goods train the most common, traction quality 4000t as example, heavily loaded direction traction current is up to 600 ~ 800A, and underloading direction traction current only has 10 ~ 40A.The general length of feeding section has 2 ~ 3 train operations about 20km.When the contact system up-downgoing is separately powered, heavily loaded direction contact system current capacity demand up to 1500A about, contact system must arrange two line feeders could be satisfied; And the underloading direction only has tens peaces, and the contact system current capacity utilizes wretched insufficiency.When conventional section post, contact system up-downgoing parallel operation are set, can only reduce at most 25% of heavily loaded direction contact system current capacity demand, heavily loaded direction contact system current capacity demand up to 1200A about, still single line feeder must be set; Underloading direction current capacity is about 400A simultaneously, and the contact system current capacity still can not get effective utilization.
Mountain railway bridge tunnel ratio is higher, line feeder is set to very inconvenience of operation maintenance.
Summary of the invention
The purpose of this invention is to provide a kind of multiple line of electrified railway section post main electrical scheme with the capacitive character electrical equipment, can effectively improve traction net current distribution, reduce loaded vehicle direction contact system current capacity demand, improve light car direction contact system current capacity degree of utilization, improve voltage levvl and power supply capacity, and reduce traction net energy loss.
It is of the present invention that to solve the problems of the technologies described above the technical scheme of taking as follows:
The present invention is with the multiple line of electrified railway section post main electrical scheme of capacitive character electrical equipment, it is characterized in that: described main electrical scheme comprises Switch equipment and capacitive character electrical equipment, and this capacitive character electrical equipment carries out parallel connection with heavily loaded direction contact system and underloading direction contact system at the feeding section end through Switch equipment.
The present invention compares with conventional section post wiring, has the following advantages and beneficial effect:
Reduce heavily loaded direction contact system current capacity demand, by selecting suitable capacitive reactances, compare maximum and can reduce loaded vehicle direction contact system current capacity approximately 50% with separating power supply, contact system self current capacity can satisfy the demands; Improve voltage levvl and power supply capacity, because the existence of capacitive reactances, electric locomotive obviously improves at the terminal voltage levvl of traction net; Under the Same Efficieney demand, reduced traction net electric current, thereby reduced traction net energy loss; Improve the over zone feeding ability, electrified railway voltage levvl under over zone feeding in mountain area is lower, and the existence of capacitive reactances will significantly improve voltage levvl.
Main electrical scheme provided by the invention both can adopt indoor or outdoor arrangement in engineering construction, also can adopt the box-type equipment arrangement, can also by portable and (or) fixed device combination forms; Switch equipment can adopt the patterns such as air insulation, switch cubicle or combined electric.
Main electrical scheme provided by the invention both can adopt complete equipment once to make, install in engineering construction, can also transform on existing conventional section post basis to form.
