Description
Technical field
This utility model relates to a kind of twin columns disconnecting switch.
Background technology
Disconnecting switch, i.e. when dividing position, has between contact and meets the insulation distance of regulation requirement and significantly disconnect mark；When closing position, can carry the switchgear of the electric current under normal loop condition and the electric current under abnormal condition (such as short-circuit) at the appointed time.
Disconnecting switch, generally referred to as high voltage isolator, i.e. rated voltage is in 1kV and above disconnecting switch thereof, often referred to simply as disconnecting switch, being to use most a kind of electrical equipment in high-voltage switch electric appliance, the principles and structure of itself is fairly simple, but owing to usage amount is big, functional reliability requires height, and the impact on electric substation, the design of power plant, foundation and safe operation is the biggest.Disconnecting switch be mainly characterized by without arc extinguishing ability, can only divide in the case of there is no load current, close circuit.Disconnecting switch is used for each step voltage, is used as to change circuit and connects or make circuit or equipment and isolated from power, and it does not stop ability, can only operate after first being disconnected by circuit with miscellaneous equipment again.Typically with the interlock of maloperation when preventing from switching on-load, it is sometimes desirable to pin prevents from disconnecting switch under the magneticaction of big fault.General one group of disconnecting switch of two each installations before and after chopper, purpose is all intended to, by chopper and isolated from power, form obvious cut-off point；Because chopper originally uses oil-break, oil-break needs often maintenance, therefore will there be obvious cut-off point two sides, is beneficial to maintenance；Generally, outgoing line cabinet is to be powered downwards by switch cubicle from bus above, one group of disconnecting switch is needed to be intended to and isolated from power before chopper, but sometimes, also the possibility of incoming call is had after chopper, as sent by the counter of other loop, capacitor etc. send by the counter of device, therefore is also required to one group of disconnecting switch after chopper.
Current existing disconnecting switch simple in construction, less stable, insulation effect is the best, and usage safety performance is general.
Utility model content
It is good that the technical problems to be solved in the utility model is to provide a kind of insulation effect, safe and reliable, compact conformation, having stable behavior reliable twin columns disconnecting switch.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of twin columns disconnecting switch, including base, first support insulator, second support insulator and insulated sleeve, described first support insulator and the second support insulator are fixed on base, on described first support insulator, the first contact base is installed, on described second support insulator, the second contact base is installed, on described first contact base, hook seat and rope sling are installed, described insulated sleeve one end is provided with connector, it is provided with rotating shaft in described connector, described rotating shaft is flexibly connected with hook seat, the described insulated sleeve other end is provided with pull bar, on described pull bar, draw-in groove is installed.
As preferably, in described insulated sleeve, it is provided with conductor.
As preferably, described hook seat and the first contact base are fixed and are connected.
As preferably, below described pull bar, it is provided with fixture.
As preferably, described pull bar is connected with insulated sleeve by fixture.
The beneficial effects of the utility model are: the first support insulator of setting, the second support insulator and insulated sleeve keep insulation effect good, and conductor is arranged in insulated sleeve, keeps safe and reliable；Rotating shaft is flexibly connected the position that can effectively regulate insulated sleeve with hook seat；The pull bar arranged can be enclosed within rope sling by draw-in groove, and holding circuit disconnects so that compact conformation, having stable behavior is reliable.
Accompanying drawing explanation
Fig. 1 is the structure chart of this utility model a kind of twin columns disconnecting switch.
Detailed description of the invention
As shown in Figure 1, a kind of twin columns disconnecting switch, including base 1, first support insulator 2, second support insulator 3 and insulated sleeve 4, described first support insulator 2 and the second support insulator 3 are fixed on base 1, on described first support insulator 2, first contact base 5 is installed, on described second support insulator 3, second contact base 6 is installed, on described first contact base 5, hook seat 14 and rope sling 7 are installed, described insulated sleeve 4 one end is provided with connector 8, it is provided with rotating shaft 9 in described connector 8, described rotating shaft 9 is flexibly connected with hook seat 14, described insulated sleeve 4 other end is provided with pull bar 10, on described pull bar 10, draw-in groove 11 is installed.
Being provided with conductor 12 in described insulated sleeve 4, insulated sleeve 4 can carry out exterior insulation to conductor 12 when conduction.
Described hook seat 14 is fixing with the first contact base 5 to be connected, and keeps sound construction reliable.
It is provided with fixture 13 below described pull bar 10, keeps easy for installation.
Described pull bar 10 is connected with insulated sleeve 4 by fixture 13 so that Stability Analysis of Structures is reliable.
The beneficial effects of the utility model are: the first support insulator of setting, the second support insulator and insulated sleeve keep insulation effect good, and conductor is arranged in insulated sleeve, keeps safe and reliable；Rotating shaft is flexibly connected the position that can effectively regulate insulated sleeve with hook seat；The pull bar arranged can be enclosed within rope sling by draw-in groove, and holding circuit disconnects so that compact conformation, having stable behavior is reliable.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
