Abstract
The invention discloses a drain device for a main breaker of a locomotive, aiming at solving the technical problems that the arc extinguishing chamber of the main breaker of the existing electronic locomotive can not timely drain water, and the like. The technical scheme thereof is mainly characterized in that a solenoid pilot actuated valve DT is connected with a controller which consists of a time relay SJ and an intermediate relay ZJ; between the input terminals 101 and 102 of a power, the solenoid pilot actuated valve DT is connected with the normally closed contact point ZJ3 of the intermediate relay in parallel, the time relay SJ is connected with the normally closed contact point ZJ2 of the intermediate relay, and the intermediate relay ZJ is connected with the normally open contact point ZJ1 of the intermediate relay and the timelag contact point SJ of the time relay. The drain device for the main breaker of the locomotive can completely drain the water accumulated in the arc extinguishing chamber of the main breaker, prevent the arc extinguishing chamber from explosion, reduce the accident of the locomotive, improve the performance of safe operation of the locomotive and be capable of effectively maintaining the normal transportation procedures. The drain device for the main breaker of the locomotive is mainly used for removing the water accumulated in the arc extinguishing chamber of the main breaker.
Description
Technical field
The present invention relates to a kind of drainage arrangement that is used for main circuit breaker of railway engine.
Background technology
Electric locomotive roof main circuit breaker is the critical component of electric locomotive cruising; the power supply that it is being undertaken between whole locomotive and the power supply network is introduced, is withdrawed from and protective effect; in a single day it break down; locomotive just can't normally come into operation; gently then locomotive breakage; heavy then cause bow net to damage, seriously disturb the normal transport production of this railway line.
From the operating position of present main circuit breaker of railway engine, the fault that its takes place is mainly reflected in following several respects: 1. main contact arcing scaling loss; 2. the arc extinguishing porcelain vase is blown up; 3. nonlinear resistance is blown up etc.Locomotive all has a lot of main circuit breaker arc control device to blow up and causes locomotive and accident between pantograph every year in service, has caused serious economy loss.Reason from the accident, main cause are in the main circuit breaker arc control device ponding to be arranged, and air is moist, cause the main contact arcing, and then blast, and be exactly that the main circuit breaker arc control device do not have timely draining and the reason of water is arranged.The present gas and water separator that uses, the water of separating will lean on manual emission, and as untimely discharging, a large amount of air waters will enter the main circuit breaker arc control device, finally cause adverse consequences.From not being very desirable by the situation of crew's draining at present, a lot of people do not have the draining custom, have in addition never arranged water, only advance and just arrange one time water when supplementally take for a short time in the storehouse, brought great potential safety hazard to locomotive.
Summary of the invention
The purpose of this invention is to provide a kind of water drainage device for main circuit breaker of railway engine that can in time drain the water away for the main circuit breaker arc control device.
The technical solution adopted for the present invention to solve the technical problems is: electromagnetically operated valve DT joins with the controller that is made of time relay sj and intermediate relay ZJ, is parallel with electromagnetically operated valve DT and meets auxiliary relay normally-closed contact ZJ between power input 101,102
3, time relay sj meets auxiliary relay normally-closed contact ZJ
2, intermediate relay ZJ meets auxiliary relay normally opened contact ZJ
1With time relay delayed contact SJ.The main power source key of power input 101,102 and locomotive links.Described controller is made of the controlling parts that is installed on the base 4, and controlling parts comprises time relay sj 1, intermediate relay ZJ 2 and binding post 3.Time relay sj 1, intermediate relay ZJ 2 and binding post 3 are installed on base 4 successively.The top of base 4 is provided with the control box cover 5 that matches with base 4 and controlling parts overall dimensions respectively.
The invention has the beneficial effects as follows: it can thoroughly drain the ponding of main circuit breaker arc control device, prevents that arc control device from blasting, and falls the generation of end locomotive accident, improves the performance of locomotive safety running, can safeguard normal transport order effectively.It is mainly used in the ponding that is used as the main circuit breaker arc control device in the electric locomotive and gets rid of.
Description of drawings
Fig. 1 is circuit theory diagrams of the present invention.
Fig. 2 is the control box structural representation.
Fig. 3 is a components and parts distributed architecture schematic diagram of the present invention.
Among the figure: 1-time relay sj, 2-intermediate relay ZJ, 3-binding post, 4-base, 5-control box cover.
Embodiment
That the invention will be further described is as follows below in conjunction with drawings and Examples:
Embodiment 1, and electromagnetically operated valve DT of the present invention joins with the controller that is made of time relay sj and intermediate relay ZJ, is parallel with electromagnetically operated valve DT and meets auxiliary relay normally-closed contact ZJ between power input 101,102
3, time relay sj meets auxiliary relay normally-closed contact ZJ
2, intermediate relay ZJ meets auxiliary relay normally opened contact ZJ
1With time relay delayed contact SJ, the main power source key of described power input 101,102 and locomotive links.In use, the water pipe of electromagnetically operated valve DT and main circuit breaker arc control device are linked, operation main power source key when locomotive operation makes power input 101,102 energisings, the electromagnetically operated valve DT work of switch on, valve open, the draining of main circuit breaker arc control device adding air pressure; The work of time relay sj energising simultaneously, the drainage works that reaches setting is after the time, time relay delayed contact SJ closure, and intermediate relay ZJ energising work and self-locking keep, auxiliary relay normally-closed contact ZJ
2, ZJ
3Disconnect, electromagnetically operated valve DT outage, valve closing, drainage works is finished, and the while time relay also cuts off the power supply and quits work.As the draining of need continuous several times, when the drainage arrangement power supply does not turn-off, should first power cutoff, then water feeding and draining device is served power supply again, and drainage arrangement could enter normal drainage works again, and it can carry out delayed setting to the time relay according to the draining required time.
The present invention is by utilizing air pressure that the main circuit breaker arc control device are carried out draining, and working method adopts discontinuous work, and the opening and closing of air pressure are by solenoid control.According to present locomotive routing situation, the number of times of operation master control power supply key in two-way process of locomotive can form and give the draining of main circuit breaker arc control device automatically main circuit breaker arc control device draining four times at least.It mainly is to be used for electric locomotive, as the control device that main circuit breaker arc control device ponding is got rid of, can thoroughly drain the ponding of main circuit breaker arc control device, prevents that arc control device from blasting, and falls the generation of end locomotive accident, improves the performance of locomotive safety running.Important technological parameters of the present invention: rated operational voltage: DC110V, specified power controlling: 3W, the drainage works time is generally: 0.5～3 second.Consult Fig. 1 and Fig. 2.
