Abstract
The utility model relates to a railway contact net is electronic mechanism of improved generation for isolator, electronic mechanism includes drive mechanism and control mechanism, be connected through the secondary cable between drive mechanism and the control mechanism, drive mechanism includes a transmission box, and this transmission box is installed in isolator's below, at internal motor and the limit switch of installing of transmission case, control mechanism includes a control box, has a control panel in that the control box is internal, and this control panel passes through the secondary cable and links to each other with the motor. The utility model has the advantages of: with drive mechanism and control mechanism separation, the limit switch among the drive mechanism is non -sensitive type of quadratic element spare with the motor, can not appear missing the condition about moving, and when utilizing control mechanism drive drive mechanism in addition, the terminal voltage is little to the influence of above -mentioned quadratic element spare in excess supply, and motor rotation number is slightly little, can ensure that the secondary control component reliably moves, avoids refusing, miss the phenomenon of moving because of control mechanism 0 leads to secondary control control mechanism 2 to produce.
Description
Technical field
The utility model relates to isolating switch and manufactures field, particularly a kind of railway contact line isolating switch improved electric mechanism.
Background technology
Electrification railway contact net isolating switch exists following problem to make isolating switch divide-shut brake unreliable at present: long line (approximately 6.5 kilometers) terminal voltage reduces, long line interference maloperation problem.
When traditional ocs isolating switch distribution actuation mechanism, the unification of linear quadratic control element is arranged in outdoor mechanism case, because long line (approximately 6.5 kilometers) terminal voltage reduces, the electromagnetic interference of long circuit causes linear quadratic control sensing element to produce tripping, malfunction, bring hidden danger to operation of power networks.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of railway contact line isolating switch improved electric mechanism, can effectively solve the problem that existing isolating switch brings because of mechanism's maloperation.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of railway contact line isolating switch improved electric mechanism, the isolating switch that this motor drive mechanism is installed on railway contact line place for actuating divides, closing operation, and its innovative point is: described motor drive mechanism comprises transmission mechanism and controlling organization;
Between described transmission mechanism and controlling organization, be connected by secondary cable;
Described transmission mechanism comprises a transmission case body, and this transmission case body is installed on the below of isolating switch, and motor and limit switch are installed in transmission case body;
Described controlling organization comprises a control casing, in control casing, has a control panel, and this control panel is connected with transmission mechanism by secondary cable and controls.
The utility model has the advantage of: in the utility model, transmission mechanism and controlling organization are separated, limit switch in transmission mechanism and motor are non-sensitive class secondary component, there will not be the situation of malfunction, while utilizing in addition controlling organization drive transmission device, long line end voltage is little on above-mentioned secondary component impact, motor speed is smaller, can guarantee linear quadratic control element action message, output order makes isolating switch correctly divide, close a floodgate, and avoids producing the phenomenon of tripping, malfunction because electromagnetic interference causes linear quadratic control sensing element.
Brief description of the drawings
Fig. 1 is the schematic diagram of railway contact line isolating switch of the present utility model with transmission mechanism in improved electric mechanism.
Fig. 2 is the schematic diagram of railway contact line isolating switch of the present utility model with controlling organization in improved electric mechanism.

Detailed description of the invention
Schematic diagram is as shown in Figure 1-Figure 3 known, railway contact line isolating switch of the present utility model improved electric mechanism, and the isolating switch that this motor drive mechanism is installed on railway contact line 9 places for actuating divides, closing operation.
Motor drive mechanism comprises transmission mechanism 6 and controlling organization 7, between transmission mechanism 6 and controlling organization 7, is connected by secondary cable 8.
Schematic diagram is as shown in Figure 1 known, and transmission mechanism 6 comprises a transmission case body 3, and this transmission case body 3 is installed on the below of isolating switch, and motor 4 and limit switch 5 are installed in transmission case body 3. By divide-shut brake order starting contactor, be communicated with ocs isolating switch motor circuit and realize divide-shut brake, delay function makes automatically to disconnect after control loop self-holding circuit a period of time, efficiently solves control loop pressure drop, severe electromagnetic environment is disturbed the tripping, the malfunction that cause.
Schematic diagram is as shown in Figure 2 known, and controlling organization 7 comprises a control casing 1, and this control casing 1 is installed on contact line switches monitoring place 10, in control casing 1, has a control panel 2, and this control panel 2 is connected with motor 4 by secondary cable. The instruction of controlling organization divide-shut brake makes control cables obtain electrical mechanisms action, and when divide-shut brake puts in place, limit switch automatic cut-off motor loop, has avoided isolating switch malfunction.
Operation principle: transmission mechanism and controlling organization are separated, limit switch 5 in transmission mechanism is non-sensitive class secondary component with motor 4, there will not be the situation of malfunction, while utilizing in addition controlling organization drive transmission device, long line end voltage is little on above-mentioned secondary component impact, and motor 4 rotating speeds are smaller, can guarantee linear quadratic control element action message, output order makes isolating switch correctly divide, close a floodgate, and avoids producing the phenomenon of tripping, malfunction because electromagnetic interference causes linear quadratic control sensing element.
The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model. The claimed scope of the utility model is defined by appending claims and equivalent thereof.
