Description
Technical field
The utility model relates to a kind of measuring apparatus, specifically VD4 type overhaul of line breaker control enclosure.
Background technology
VD4 type isolating switch, in the time of operation and testing position, provides control, the accumulation power supply of isolating switch, and realizes the operation control of isolating switch by aviation plug.Now, tank circuit is realized the electric energy-stored of spring by energy storage motor, and divide-shut brake control all can realize by divide-shut brake coil motion.But isolating switch is in the time of maintenance position, aviation plug be cannot connect and corresponding control, accumulation power supply also just lost, the combined floodgate electrical apparatus release of the dead electricity coil of isolating switch mechanical latching isolating switch after power supply out of hand is to prevent reliably separating brake of isolating switch, in the time closing a floodgate in maintenance position, must operate by manual unlocking dead electricity coil, and can only thread off and operate by Manual press divide-shut brake, can only carry out spring energy-storage by manual energy storage rod after losing accumulation power supply.By manual operation and energy storage, there are certain hazards, spring easily causes personal injury while dropout, and manual energy storage speed is slow, reduces overhaul efficiency.
The mechanical characteristic test of isolating switch is to control point closing operation of isolating switch by the divide-shut brake order of tester, and the break-make that detects isolating switch two fractures judges the data such as the branch wire time, divide-shut brake speed, operation curve of isolating switch.While carrying out mechanical characteristic test due to isolating switch, need the control power supply of external tester to control deciliter action of isolating switch, but present stage, all testers did not all have the joint of VD4 type isolating switch coupling, so can not carry out mechanical characteristic test to this equipment, cannot ensure the safe operation of equipment always.
Utility model content
In order to address the above problem, the utility model provides VD4 type overhaul of line breaker control enclosure, can solve the problem of isolating switch at out of hand, the accumulation power supply in maintenance position.
The utility model is by the following technical solutions: VD4 type overhaul of line breaker control enclosure, it is characterized in that, comprise box body, on described box wall, be embedded with power switch, test joint, energy storage air switch, aviation plug, switch and divide-shut brake control handle, in described box body, be provided with rectifier, the input end of described rectifier connects a circumscripted power line with plug, the output terminal of described rectifier connects one end of power switch, the other end of power switch connects one end of a moving contact joint test joint of switch stationary contact and switch, the test joint other end connects the contact pin of aviation plug, one end of another moving contact connecting dividing lock control handle of switch, the other end of divide-shut brake control handle connects the contact pin of aviation plug, the 3rd moving contact of switch connects energy storage air switch one end, the energy storage air switch other end connects the contact pin of aviation plug.
Further, described rectifier is the full wave rectifier of 220V AC-DC.
Further, described control enclosure also comprises mechanic character tester, and described mechanic character tester is connected with test joint.
The beneficial effects of the utility model are: the utility model has solved that isolating switch is out of hand in maintenance position, the problem of accumulation power supply, can realize the electric energy-stored and electric operating of isolating switch in maintenance position, hand tripping operation and manual energy storage are avoided, improve overhaul efficiency, effectively avoided personal injury.In addition, increased the test loop of isolating switch in maintenance position, can realize the switching of the electronic control of isolating switch and controlling test, can realize the testing mechanical characteristic of isolating switch, checkout equipment defect in time, improves equipment reliability of operation.
Brief description of the drawings
Fig. 1 is circuit theory schematic diagram of the present utility model.
In figure: 1 rectifier, 2 power switches, 3 switches, 4 divide-shut brake conversion handles, 5 test joints, 6 energy storage air switches, 7 aviation plugs.
Embodiment
VD4 type overhaul of line breaker control enclosure of the present utility model comprises box body, on described box wall, be embedded with power switch 2, test joint 5, energy storage air switch 6, aviation plug 7, switch 3 and divide-shut brake control handle 4, in described box body, be provided with the full wave rectifier 1 of 220V AC-DC, as shown in Figure 1, the input end of described rectifier connects a circumscripted power line with plug, the output terminal of described rectifier connects one end of power switch, the other end of power switch connects one end of a moving contact joint test joint of switch stationary contact and switch, the test joint other end connects the contact pin of aviation plug, one end of another moving contact connecting dividing lock control handle of switch, the other end of divide-shut brake control handle connects the contact pin of aviation plug, the 3rd moving contact of switch connects energy storage air switch one end, the energy storage air switch other end connects the contact pin of aviation plug.
Before use, be plugged corresponding with isolating switch side aviation plug, the external control line of mechanic character tester is connected with test joint, the fracture line of tester is connected on the dynamic and static contact both sides of isolating switch.
When use, connect alternating current 220V power supply, switch is got to the branch road at energy storage air switch place, power turn-on switch and tank circuit air switch, can connect tank circuit, can automatic energy storage energy storage in the situation that at isolating switch.
After energy storage completes, need to carry out inspection operation time, switch is got to the branch road at combined floodgate control handle place, rotation divide-shut brake control handle can be realized the breaking-closing operating of isolating switch.
Need to carry out mechanical characteristic test time, switch is got to the branch road at test joint place, then opened mechanic character tester.
Because tool characteristic tester needs to be used in conjunction with this control enclosure, therefore tool characteristic tester can be fixed on this control enclosure, conveniently carry simultaneously.
Except structure described in the utility model, all the other are prior art.
The above is preferred implementation of the present utility model; for those skilled in the art; not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications are also regarded as protection domain of the present utility model.
