Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Consult Fig. 1, a kind of high-tension switch equipment used in highland of the utility model (can be applicable to 4000 meters of height above sea level) comprises cabinet 1, fixed sealing type circuit breaker 2, contact box 3, fixed contact 4, lower row 5, current transformer 6, insulating barrier 7, earthed switch 8, insulator 9, bus casing 10, main busbar 11, the upper row of propping up 12 and curtain formula valve mechanism 13.
Cabinet 1 becomes the A of control room, handcart chamber B, bus-bar room C and the D of cable vault by baffle for separating; Fixed sealing type circuit breaker 2, contact box 3, curtain formula valve mechanism 13 are loaded on handcart chamber B, and fixed contact 4, upper row 12, lower row 5 are contained on contact box 3, and fixed contact 4 comprises the first fixed contact and the second fixed contact, and fixed sealing type circuit breaker 2 is for can extract parts out; Described bus casing 10, insulator 9, main busbar 11 are loaded on bus-bar room C; Described current transformer 6, earthed switch 8, insulating barrier 7 are loaded on the D of cable vault.Major loop by main busbar 11 through upper row the 12, first fixed contact, fixed sealing type circuit breaker 2, the second fixed contact, lower arrange 5, the serial connection such as current transformer 6 consisted of.
When a kind of high-tension switch equipment used in highland of the utility model (4000 meters of height above sea level) uses, first fixed sealing type circuit breaker 2 is pushed the interior test position of cabinet 1 (as shown in Figure 1) outward by cabinet, and handcart advancing mechanism left and right stop pin and cabinet 1 are locked.Again the subsidiary loop plug is pegged graft firm, all cabinet doors are shut pinning.This moment can be in the situation that major loop access failure rival car divides, the combined floodgate electric operation.
In the time of handcart will being put into operation, should be first with earthed switch 8 separately.Again the interlocking of the ground connection on handcart advancing mechanism handle is pulled to low order end.Then open with the handle crank and advance the jack wicket, be inserted into jack, clockwise rotate crank, until advance the clutch automatic trip from.This moment, circuit breaker was in service position (as shown in Figure 2), and metal dampers is opened, and major loop is connected.Shut its jack wicket with the handle crank, can close, divide operation it by control loop, and the operation of giving, have a power failure.This moment, each cabinet Men Jun was blocked, and can't open except instrument door.
If prepare handcart is withdrawed from from the service position, at first should confirm circuit breaker at gate-dividing state, then open its jack wicket with the handle crank, be inserted into jack and rotate counterclockwise crank, until advance the clutch automatic trip from taking off crank, close upper handle crank jack.At this moment, circuit breaker has retreated to test position, and major loop disconnects fully, and metal dampers is closed.
If want switching devices to overhaul, the earthed switch that should first close, the cabinet door can be opened.Open cabinet behind the door, first remove the subsidiary loop plug, more inwardly left and rightly pull that handcart is right, left handle, with the handcart release and pull out outside cabinet.Can switching devices carry out safety inspection this moment.
