Abstract
The invention discloses a high-voltage circuit breaker. The circuit breaker is a circuit breaker with a disconnecting switch. The circuit breaker comprises a circuit breaker body and an operating mechanism which controls the switching on and switching off of the circuit breaker body; the circuit breaker further comprises an upper disconnecting switch contact arm, a lower disconnecting switch contact arm, an upper disconnecting switch transmission shaft, a lower disconnecting switch transmission shaft and a sprocket-chain mechanism; the upper disconnecting switch transmission shaft receives an external torque and converts rotary motion into vertical rectilinear motion of the upper disconnecting switch contact arm through a transmission mechanism; the sprocket-chain mechanism conveys the external torque to the lower disconnecting switch transmission shaft; the lower disconnecting switch transmission shaft converts rotary motion to vertical rectilinear motion of the lower disconnecting switch contact arm through a transmission mechanism; and the upper disconnecting switch contact arm and the lower disconnecting switch contact arm are respectively provided with an upper disconnecting switch contact and a lower disconnecting switch contact. According to the high-voltage circuit breaker of the invention, the upper disconnecting switch contact arm and the lower disconnecting switch contact arm are adopted, so that the circuit breaker and the disconnecting switch are integrated, and therefore, occupied space can be greatly reduced, and the size of equipment can be greatly decreased, and the high-voltage circuit breaker is safe and reliable and is convenient to transport and install.
Description
Technical field
The present invention relates to a kind of primary cut-out.
Background technology
At present, existing primary cut-out is generally independent component, is connected with isolator by bus, often causes quality heavy, bulky, and conduction loop length, tie point are many, and heat dispersion is poor, is unfavorable for safe operation.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that the primary cut-out that a kind of volume is less, security is high.
The primary cut-out of the present invention is the isolating switch of band isolator, comprise breaker body and be its provide power control its close a floodgate, the actuating mechanism of point lock, described isolating switch also comprises the upper isolator contact arm being installed on breaker body, lower isolator contact arm, upper isolator transmission shaft, lower isolator transmission shaft, sprocket wheel link chain mechanism; Described upper isolator transmission shaft accepts external torque, through transmission rig, rotary motion is turned into the translational motion up and down of upper isolator contact arm, the external torque that upper isolator transmission shaft accepts is passed to lower isolator transmission shaft by described sprocket wheel link chain mechanism, rotary motion is turned into the translational motion up and down of lower isolator contact arm by described lower isolator transmission shaft through transmission rig, upper isolator contact arm is provided with the dynamic contact of isolator, and lower isolator contact arm is provided with the dynamic contact of lower isolator.
In addition, described upper and lower isolator contact arm is also respectively equipped with arm insulation sleeve.
The invention has the beneficial effects as follows:
The primary cut-out of the present invention uses the isolating switch with isolator, adopt the design of upper and lower isolator contact arm, isolating switch and isolator are integrated, without the need to extra transmission rig, greatly reduce the space taken, reduce equipment volume significantly, safe and reliable and be convenient to transport install.
Accompanying drawing explanation
Fig. 1 is the structural representation of isolating switch in the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the primary cut-out of the present invention is the isolating switch of band isolator, comprise the breaker body 17 being installed on frame body 1 and provide power controller to close a floodgate for it, divide the actuating mechanism 5 of lock, actuating mechanism 5 transmits power by transmission rod 2, and described isolating switch also comprises the upper isolator contact arm 14 being installed on breaker body, lower isolator contact arm 18, upper isolator transmission shaft 7, lower isolator transmission shaft 3, sprocket wheel link chain mechanism;Described upper isolator transmission shaft 7 accepts external torque, through transmission rig, rotary motion is turned into the translational motion up and down of upper isolator contact arm 14, described sprocket wheel link chain mechanism comprises two sprocket wheels 4, 8 and chain 6, the external torque that upper isolator transmission shaft 7 accepts is passed to lower isolator transmission shaft 3, rotary motion is turned into the translational motion up and down of lower isolator contact arm 18 by described lower isolator transmission shaft 3 through transmission rig, upper isolator contact arm 14 is provided with the dynamic contact 10 of isolator, lower isolator contact arm 18 is provided with the dynamic contact 19 of lower isolator.
Also being respectively equipped with arm insulation sleeve 16 on described upper and lower isolator contact arm 14,18, isolator contact arm adopts upper and lower linear telescopic to move, and can be wrapped in arm insulation sleeve 16 when point lock. When upper and lower isolator contact arm moves up and down, keep excellent electric contact by slider 15 and the conducting plates 13 being located at bottom dynamic contact 10 or 19.
