Abstract
The present invention discloses a grounding handcart non-station interlocking mechanism used for a PT cabinet. The grounding handcart non-station interlocking mechanism used for the PT cabinet is characterized by comprising a stroke switch and a switch support, wherein the stroke switch is in series connection with a power supply circuit of the chassis electromagnets of the breaker handcarts of an incoming line cabinet, a segmentation cabinet and an isolation cabinet at the segment in which the PT cabinet is located, and the switch support is erected in the PT cabinet; the stroke switch is arranged on the switch support, when a plum blossom tentacle of a grounding handcart matching the PT cabinet is not separated, the contact arm of the stroke switch is pressed by the grounding handcart, and the stroke switch disconnects the power supply of the chassis electromagnets of the breaker handcarts, so that the positions of the breaker handcarts are locked. The present invention can provide an interlocking mechanism among the handcarts of a grounding cabinet, the incoming line cabinet and a buscouple cabinet.
Description
Technical field
The present invention relates to High voltage power supply equipment field, the non-station interlocking machine of the especially a kind of earth handcart for PT cabinet
Structure.
Background technology
The requirement of electrical network project anti-misoperation interlocking between cabinet is increasing, because most of system station has collocation at present
Earth handcart, uses when convenient maintenance, then the interlocking between earth handcart and incoming line cabinet, mother cabinet handcart becomes
The design point of important consideration；If the handss of incoming line cabinet or segmentation cabinet still can be operated when earth handcart is in PT cabinet
Car, so very likely causes primary side short circuit, and switch cubicle explodes, and consequence is extremely serious；How to design earth handcart and inlet wire
Interlocking mechanism between cabinet, mother cabinet handcart, is a research direction.
Because with the electromagnet mechanism at chassis, incoming line cabinet, mother cabinet handcart to determine whether it may move, therefore if
Powered by the electric magnet of rational mechanism control incoming line cabinet, mother cabinet handcart, the interlocking between handcart will be enabled.
Content of the invention
The present invention proposes a kind of non-working-position interlock mechanism of earth handcart for PT cabinet, using the teaching of the invention it is possible to provide ground connection cabinet and inlet wire
Interlock mechanism between cabinet, mother cabinet handcart.
The present invention employs the following technical solutions.
A kind of non-working-position interlock mechanism of the earth handcart for PT cabinet, described interlocking mechanism includes travel switch, switch
Frame；Described travel switch is series at the incoming line cabinet of PT cabinet place section, segmentation cabinet, the circuit breaker cart chassis electric magnet of isolation cabinet
On power supply circuits, described switch bracket in PT cabinet, described travel switch on switch bracket, when PT cabinet institute matingly handss
When the Flos Mume tentacle of car does not separate, the contact arm of travel switch is grounded handcart compressing, travel switch cut-off breaker handcart bottom
The power supply of disk electric magnet makes the position of circuit breaker cart be locked.
Described travel switch is bent-arm travel switch.
Described earth handcart is provided with collision block, when the Flos Mume tentacle of earth handcart does not separate, the collision block on earth handcart
The contact arm of compressing travel switch.
Described switch bracket is the bent plate at the secondary slot of earth handcart Flos Mume tentacle.
In the present invention, described switch bracket in PT cabinet, described travel switch on switch bracket, travel switch
Contact arm leans out to the operating position of earth handcart；Because when the secondary line access failure of PT cabinet, PT cabinet still needs to be grounded handss
Keep interlocking between car and circuit breaker cart, therefore travel switch in PT cabinet, make the action of travel switch not be subject to cabinet exopathogenic factor
Element interference, and the action of PT cabinet other part can be accepted when needed and respond, so that it is guaranteed that when the secondary line of PT cabinet does not connect
When logical, still keep between earth handcart and circuit breaker cart interlocking.
In the present invention, described travel switch is bent-arm travel switch；This design considers earth handcart Mume flower contact
The problem of first and second contacting travel is so that only after Mume flower contact is kept completely separate, what earth handcart ability release travel switched connects
Contact arm（Connecting lever）.
In the present invention, described earth handcart is provided with collision block, when the Flos Mume tentacle of earth handcart does not separate, earth handcart
On collision block oppress travel switch contact arm；This design can ensure that earth handcart can press travel switch, and due to not
Big change is carried out to original PT cabinet, thus without the use of impact earth handcart.
Brief description
The present invention is described in more detail with reference to the accompanying drawings and detailed description：
Accompanying drawing 1 is the schematic diagram of the present invention
In figure：1- collision block；2- travel switch；3- contact arm；Contact arm when 4- is oppressed；5- is in forceful contact arm state
Collision block；6- Flos Mume tentacle；7- earth handcart.
Specific embodiment
As shown in figure 1, a kind of non-working-position interlock mechanism of the earth handcart for PT cabinet, described interlocking mechanism includes stroke and opens
Close 2, switch bracket；Described travel switch 2 is series at the incoming line cabinet of PT cabinet place section, segmentation cabinet, the circuit breaker cart of isolation cabinet
On the power supply circuits of chassis electric magnet, described switch bracket in PT cabinet, described travel switch 2 on switch bracket, when
PT cabinet matingly handcart 7 Flos Mume tentacle 6 do not separate when, the contact arm 3 of travel switch 2 is grounded handcart 7 and oppresses, and stroke is opened
The power supply closing 2 cut-off breaker handcart chassis electric magnet makes the position of circuit breaker cart be locked.
Described travel switch 2 is bent-arm travel switch.
Described earth handcart 7 is provided with collision block 1, when the Flos Mume tentacle 3 of earth handcart 7 does not separate, on earth handcart 7
Collision block 1 oppresses the contact arm 3 of travel switch 2, contact arm attitude such as labelling 4 indication now, collision block position so such as labelling 5
Indication.
Described switch bracket is the bent plate at the secondary slot of earth handcart Flos Mume tentacle.
