Description
Technical field
The utility model is related to technical field of electric equipment, specially a kind of JP cabinets inlet wire switch anti-misoperation device.
Background technology
JP cabinets are the electrical equipments for being widely used in rural power grids platform area distribution in power system, and it is protection low pressure which acts on
Line security reliability service and the reallocation of platform area electric energy, due to rural power grids larger, JP cabinet conducts by weather, ambient influnence
An important electrical equipment in power system, it is often necessary to manually stopped power transmission operation.
JP cabinets service entrance switch generally uses HD11- type isolation switch, and the isolation switch itself does not possess arc extinguishing ability,
Actually stop easily on-load in power transmission operation to draw（Close）Disconnecting link, in the case that load is larger, easily causes arc short-circuit so as to jeopardizing
The person, equipment safety.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of JP cabinets inlet wire switch anti-misoperation device, which is
FWZ-1 type anti-misoperation apparatus, carry out anti-misoperation locking by mechanically and electrically two aspects to inlet wire isolation switch.
The utility model solves technical problem and adopts the following technical scheme that：
A kind of JP cabinets inlet wire switch anti-misoperation device is provided, which mainly includes cabinet, the metering installed in solid interior
Room, the cabinet include that two fan clamshell doors, wherein side door body center are provided with inlet wire disconnecting link, entering on the inside of inlet wire disconnecting link
Line indoor location has anti-misoperation apparatus, opposite side door body medial center position to be provided with lock- receiving aperture, the anti-misoperation apparatus
Mainly include that electromagnetic lock DS, the breaker TA being connected on inlet wire circuit, breaker TA are connected to outlet switch QF, outlet switch
In the load circuit that 3QF and load elements are located, which chooses two outlet switchs between outlet switch QF, outlet switch 3QF
Normally closed auxiliary node 1QF and 2QF, the outlet switch normally closed auxiliary node 1QF, 2QF and electromagnetic lock DS connect to be formed and control back
Road.
Preferably, the electromagnetic lock DS normally closed with outlet switch auxiliary node 1QF, 2QF control loops to be formed of connecting connect
Enter 220V AC powers.
Compared with prior art, its advantage is the utility model：Its arrange anti-misoperation apparatus, by machinery and
Electric two aspects carry out anti-misoperation locking to inlet wire isolation switch, inlet wire under any non-all the way disconnection of wire-outgoing breaker
Isolation switch cannot all carry out drawing operation, only after determining that all outlet open circuits disconnect, after electricapparatus lock release,
Drawing isolation switch operation can be just carried out, the behaviour violating the regulations of JP cabinets on-load drawing disconnecting link in power transmission operation is stopped can be effectively prevented
Make behavior.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Embodiment in based on the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
As shown in Figures 1 to 3, a kind of JP cabinets inlet wire switch anti-misoperation device, its mainly include cabinet 1, are arranged on solid 1
Internal measuring room 4, the cabinet 1 include that two fan clamshell doors, wherein side door body center are provided with inlet wire disconnecting link 2, enter
Anti-misoperation apparatus 5 are installed in the inlet wire room on the inside of line disconnecting link 2, opposite side door body medial center position is provided with lock- receiving aperture 3,
The anti-misoperation apparatus 5 are main to include that electromagnetic lock DS, the breaker TA being connected on inlet wire circuit, breaker TA are connected to out
In the load circuit that wiretap QF, outlet switch 3QF and load elements are located, which is between outlet switch QF, outlet switch 3QF
Choose the normally closed auxiliary node 1QF and 2QF of two outlet switchs, the outlet switch normally closed auxiliary node 1QF, 2QF and electromagnetic lock
DS connects to form control loop.
For further optimisation technique scheme, the electromagnetic lock DS normally closed with outlet switch auxiliary node 1QF, 2QF connect
The control loop of formation accesses 220V AC powers.
Operation principle：Electromagnetic lock DS will be locked for 2 place service entrance switch room wicket of disconnecting link, and operating personnel cannot open, so as to
Feed isolating switch operation cannot be carried out；Normally closed auxiliary node 1QF, 2QF series winding Access Control loop of electromagnetic lock DS, outlet switch
In, only when outlet switch QF and 3QF disconnect, outlet switch normally closed auxiliary node 1QF, 2QF are also turned on, electromagnetic lock DS
Powered, operating personnel can open locking, carry out feed isolating switch operation, if any one outlet switch does not disconnect, control
Loop processed is obstructed, and electromagnetic lock DS does not open, and operating personnel cannot open locking so as to preventing maloperation, it is ensured that personnel and equipment
Safety.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although being described in detail to the utility model with reference to the foregoing embodiments, for those skilled in the art
For, which still can be modified to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Equivalent is carried out, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements that is made etc.,
Should be included within protection domain of the present utility model.
