Abstract
The utility model discloses a kind of high-voltage alternating current isolating switch, it is characterised in that including installing plate, installing plate is provided with a pair of posts insulator, and the top of two support insulators connects a line bank by fixed plate respectively；One of line bank is flexibly connected with one end of plug-in strip, and another line bank is connected by the other end of self-locking structure and plug-in strip；The self-locking structure includes the compression spring that one end is fixedly connected with plug-in strip, and the other end of compression spring is connected with operating mechanism；When compression spring stretches, operating mechanism is in gate-dividing state；When compression spring is compressed, operating mechanism is in "on" position.The utility model product structure is reasonable, firmly, can run, work well by batch in heavily contaminated, ruthless area safe and stable operation, reliability is done, and switching accuracy is high, and nimbly and freely, security and stability is high.
Description
Technical field
A kind of 12kV power systems high-voltage alternating current isolating switch is the utility model is related to, it is defeated installed in 10-12kV high pressures
On distribution line, for cutting off and closing the non-loaded individual event for having voltage or three-phase circuit.
Background technology
Traditional high-voltage alternating current isolating switch is simple in construction, by the composite insulator 18 of 1 busbar of line bank, 6 operating mechanism 7
And the part of installing plate 19 5 composition.Line bank is easily deformed；Insulator air insulation distance deficiency before and after busbar connection；It is multiple
The creep age distance of conjunction insulator is small and connection plate is single bolt, easily loosens and turns to.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of suitable for heavily contaminated, one kind of ruthless area
12kV high-voltage alternating current isolating switch.
In order to solve the above problems, the technical solution of the utility model there is provided a kind of high-voltage alternating current isolating switch, its
It is characterised by, including installing plate, installing plate are provided with a pair of posts insulator, the top of two support insulators is respectively by solid
Fixed board connects a line bank；One of line bank is flexibly connected with one end of plug-in strip, and another line bank passes through self-locking knot
The other end of structure and plug-in strip connects；The self-locking structure includes the compression spring that one end is fixedly connected with plug-in strip, compression spring
The other end is connected with operating mechanism；When compression spring stretches, operating mechanism is in gate-dividing state；When compression spring is compressed, operation
Mechanism is in "on" position.
Preferably, the plug-in strip is combined using at least a piece of busbar.
It is highly preferred that the plug-in strip is combined using two panels busbar.
The utility model is mainly used on high pressure electric line, in the power system for exchanging 50Hz, voltage 10kV, is used for
The non-loaded individual event for having voltage or three-phase circuit are cut off and closed, ensures the safety of High-Voltage Electrical Appliances and device in service work,
Play isolation voltage, it is impossible to with cutting off, putting into load current and cut-off short circuit current, can only be used to not produce powerful electricity
Some handover operations of arc.
The utility model product structure is reasonable, firmly, can be passed through in heavily contaminated, ruthless area safe and stable operation
Cross batch to run, work well, reliability is done, and switching accuracy is high, and nimbly and freely, security and stability is high.
Brief description of the drawings
Fig. 1 is provided by the utility model
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in figure 1, being a kind of high-voltage alternating current isolating switch provided by the utility model, it includes installing plate 19, installation
Plate is provided with a pair of posts insulator 18, and the top of two support insulators 18 connects a line bank by fixed plate 16 respectively
1；One of line bank 1 is flexibly connected with the one end of plug-in strip 6 (plug-in strip 6 is combined using two panels busbar), and another connects
Line row 1 is connected by self-locking structure with the other end of plug-in strip 6；The self-locking structure includes the pressure that one end is fixedly connected with plug-in strip 6
Contracting spring 9, the other end of compression spring 9 are connected with operating mechanism 7；When compression spring stretches, operating mechanism 7 is in separating brake shape
State；When compression spring is compressed, operating mechanism 7 is in "on" position.
The operating mechanism 7 provided with forced locking device contacts stable and firm after combined floodgate, now, loop conducting.
The utility model is structurally simple, economical, easy to use, is mainly used on high pressure electric line, exchange 50Hz, electricity
In the power system for pressing 10kV, for cutting off and closing the non-loaded individual event for having voltage or three-phase circuit, ensure High-Voltage Electrical Appliances and
Safety of the device in service work, plays isolation voltage, it is impossible to with cutting off, putting into load current and cut-off short-circuit electricity
Stream, it can only be used to not produce some handover operations of powerful electric arc.
The utility model can be run, effect is good in heavily contaminated, ruthless area safe and stable operation by batch
Good, property indices reach the requirement of GB1985 and IEC62271-102 standards after testing.
