Abstract
The invention discloses a disconnecting switch. The disconnecting switch comprises a rack, a rotating shaft, insulators and a conductive rod, wherein the rotating shaft is arranged in the rack; the insulators are arranged on the rack; the insulators are fixedly connected with the rack; a first bracket and a second bracket are arranged on the insulators separately; a moving contact is arranged on the first bracket; the moving contact is electrically connected with the conductive rod; the second bracket is provided with a tulip contact and a conductive plate; a bearing and a driving rod are mounted on the rotating shaft; the bearing is rotationally connected with the rotating shaft; a connecting lever is arranged on one side of the driving rod; and the connecting lever is hinged with the conductive rod and the driving rod separately. The disconnecting switch is stable and reliable in actions, long in service life, convenient to install, and high in safety.
Description
Technical field
The present invention relates to a kind of isolating switch.
Background technology
Isolating switch,, in the time dividing position, the insulation distance that having between contact conforms with the regulations requires and significantly disconnection indicate; In the time that co-bit is put, can carry electric current under normal loop condition and the switchgear of for example, electric current under exceptional condition (short circuit) at the appointed time.
Isolating switch, generally refer to high voltage isolator, be that rated voltage is at 1kV and above isolating switch thereof, conventionally referred to as isolating switch, be in high-voltage switch electric appliance, to use maximum a kind of electrical equipment, the principles and structure of itself is fairly simple, but because use amount is large, functional reliability requires high, and the impact of design, foundation and safe operation on electric substation, power plant is all larger. The main feature of isolating switch is without arc extinguishing ability, can only in the situation that there is no load current, divide, close circuit. Isolating switch is for each step voltage, connects or makes circuit or equipment and isolated from power as changing circuit, and its ability that do not stop, operate after can only be first will circuit disconnecting with miscellaneous equipment again. Generally the interlock of maloperation when preventing switch band load, needs pin to prevent cut-off switch under the magneticaction of large fault sometimes. Generally one group of isolating switch of two each installations before and after breaker, object is all by breaker and isolated from power, to form obvious cut-off point; Because what breaker originally adopted is oil-break, oil-break needs often maintenance, therefore two sides will have obvious cut-off point, is beneficial to maintenance; Generally, outgoing line cabinet is to power downwards by switch cubicle from bus above, before breaker, needing one group of isolating switch is to want and isolated from power, but sometimes, also the possibility that has incoming call below of breaker, as sent by the counter of other loop, the counter of the devices such as capacitor sent, thus breaker also need below one group of isolating switch.
Current existing isolator operation inconvenience, action stability is lower, and usage safety performance is not high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of reliable and stable, and long service life is easy for installation, the isolating switch that security performance is high.
For addressing the above problem, the present invention adopts following technical scheme: a kind of isolating switch, comprise frame, rotating shaft, insulator and conducting rod, described rotating shaft is located in frame, described insulator is located in frame, described insulator is fixedly connected with frame, on described insulator, be respectively arranged with the first support and the second support, on described the first support, be provided with moving contact, described moving contact and conducting rod are electrically connected, on described the second support, be provided with Mume flower contact and conductive plate, bearing and drive rod are installed in described rotating shaft, described bearing and rotating shaft are rotationally connected, described drive rod one side is provided with Abduction arm, described Abduction arm is hinged with conducting rod and drive rod respectively.
As preferably, described conductive plate and Mume flower contact are electrically connected, and Mume flower contact patches reliably, can significantly improve through-current capability and the dynamic and thermal stability performance of switch.
As preferably, described insulator is inclination angle and arranges, and keeps easy for installation.
As preferably, described the first support is fixedly connected with insulator respectively with the second support, and holding structure is reliable and stable.
As preferably, described conducting rod is round copper pipe conducting rod, keeps conductive effect good.
Beneficial effect of the present invention is: the drive rod of setting can rotate in rotating shaft, drives Abduction arm that conducting rod is moved horizontally, thus the break-make of control circuit, bearing keeps rotational stability high, and conductive plate facilitates in mounting circuit.
