Detailed description of the invention
Fig. 1 is a kind of main view of the potting breaker of 220kV single phase operation；
Fig. 2 is a kind of cross-sectional view of the potting breaker of 220kV single phase operation.
Specific embodiment
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
The utility model be a kind of 220kV single phase operation potting breaker, as shown in Figure 1 and Figure 2, by arc-chutes 5,
Shell 4, operating mechanism 7, bracket 6, conductor 3, connecting lever 9, pull rod 8, switching shell 2, the connection composition of casing 1.The outside of arc-chutes 5
Equipped with shell 4, arc-chutes 5, shell 4 are installed on bracket 6, and arc-chutes 5 are connect by conductor 3 with entry/exit line is crossed, and casing 1 is logical
Switching shell 2 is crossed to connect with shell 4.Shell 4, transferring forms seal between shell 2, casing 1, and arc-chutes 5, conductor 3 are all provided with
In in seal, i.e., arc-chutes 5, conductor 3 are sealingly mounted at shell 4, switching shell 2, in casing 1.
The angle [alpha] formed between the both ends of switching shell 2 is 110 °~170 °, i.e. casing 1 and the angle of horizontal direction is
20 °~80 °.Dielectric filled with specified gauge pressure inside seal, specified gauge pressure are 0.1~0.8MPa.
Arc-chutes 5 are made of dynamic side and quiet side, and dynamic side is connect with 9 one end of connecting lever, and 9 other end of connecting lever and 8 one end of pull rod connect
It connects, 8 other end of pull rod is connect with operating mechanism 7, and operating mechanism 7 drives arc-chutes 5 to complete the separating brake of horizontal direction, close a floodgate and grasp
Make；Quiet side is connect with conductor 3.Arc-chutes 5 are single break or multi-break arc-chutes.Shell 4 is rolled by monolith plate, seam
Locate soldering, structure is simple, handling ease.
The working principle and its course of work of the utility model are as follows：
Breaker switching-on operation：
After breaker is connected to combined floodgate order, the switching-in spring decrement release of operating mechanism 7 is converted into kinetic energy, mechanism
Connecting lever drives pull rod 8 to move downward, and pull rod 8 pushes connecting lever 9 to move downward, and arc-chutes 5 are made of dynamic side and quiet side, moves side
In the case where connecting lever 9 moves downward thrust with the quiet side contacts in arc-chutes 5, breaker switching-on operation is completed.When breaker is run, it is
Unite electric current from side entry/exit line via in casing 1 conductor, conductor 3, the arc-chutes 5 of "on" position, conductor 3, in casing 1
Conductor flows to other side entry/exit line.
Breaker open operation operation：
After breaker is connected to separating brake order, the tripping spring decrement of operating mechanism 7 discharges, and is converted into kinetic energy, mechanism
Connecting lever drives pull rod 8 to move right, and pull rod 8 pulls connecting lever 9 to move right, and arc-chutes 5 are made of dynamic side and quiet side, moves side
It is separated in the case where connecting lever 9 moves right pulling force with the quiet side in arc-chutes 5, completes breaker open operation operation.Due to breaker open operation,
The electric current that breaker carries when running causes system power not between the entry/exit line of two sides because arc-chutes 5 move the separation of side and quiet side
The purpose for disconnecting power grid is played in circulation.
