Description
Technical field
The present invention relates to electric power safeguard technical field, particularly, relate to a kind of water-tight device for circuit breaker mechanism case.
Background technology
Before 2002, Siemens 3AP1FG circuit breaker mechanism case does not design outer, case top, and along with the circuit breaker growth of running time, mechanism case rubber cushion aged deterioration, the in the situation that of rainy in summer, easily causes mechanism case infiltration.At present, the seriousness of this defect is more and more obvious, 8-9 month in 2011, station, the 110kV east of a river has 5 circuit breakers to occur circuit breaker mechanism case infiltration situation simultaneously, cause mechanism case bottom to occur ponding, cause very big potential safety hazard to the safe and stable operation of substation equipment, can only take at present interim bandaging strapping processing, cannot fundamentally solve.
Owing to there being accelerator in mechanism case, accelerate the aging speed of mechanism case seal gasket, change rubber cushion and also can only play the object that the short time prevents infiltration, need to often change very labor intensive material resources, and can not guarantee not seep water completely.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of water-tight device for circuit breaker mechanism case, and this water-tight device is arranged on short-circuiting device mechanism case top, can effectively prevent that rainwater from entering.
The present invention addresses the above problem adopted technical scheme:
For the water-tight device of circuit breaker mechanism case, comprise be arranged on mechanism case top transverse slat, be fixed on column on four angles of transverse slat, be fixed on the inverted V-shaped splash guard on column top; Two root posts near the mechanism case back side are also separately fixed on two supports of mechanism case by anchor ear; On described transverse slat, also offer rectangular through slot, groove runs through the front and back of transverse slat, is provided with a rectangle splash guard in this groove, and this rectangle splash guard can move forward and backward in groove; Described inverted V-shaped splash guard is made up of two straight plates and the arc that is connected to two straight plate lower ends, and two straight plate upper ends are fixed together, and lower end is downward-sloping towards the both sides of mechanism case respectively, forms v-shaped structure; Arc upper end connects straight plate lower end, and lower end is unsettled, and the center of circle is towards oblique upper, and the circular arc of arc section constitution mechanism case dorsad, and the tangent line of circular arc end is parallel to horizontal plane.The circular arc of aforementioned arc section constitution dorsad mechanism case refers on left and right directions, circular arc of arc section constitution, the opening of this circular arc mechanism case dorsad, also the center of circle of the circular arc of the arc section constitution in left side is towards upper left side, and the center of circle of the circular arc of the arc section constitution on right side is towards upper right side; Aforementioned circular arc end refers to the final stage circular arc that is positioned at below of the circular arc of arc section constitution, and the tangent line of this section of circular arc is parallel with horizontal plane.Water-tight device in this programme is mainly used in circuit breaker mechanism case old-fashioned, that do not design waterproof outer, the main means that adopt are included in above-mentioned transverse slat, inverted V-shaped splash guard are set on mechanism case, rainwater is blocked by inverted V-shaped splash guard, flow to mechanism case both sides, can avoid access mechanism case, there is good waterproof effect.Can be used as whole water-tight device installs support to transverse slat on mechanism case on the one hand, on the other hand also as secondary water-tight device.And two lower ends of inverted V-shaped splash guard adopt arc design, can prevent that rainwater from directly flowing down with linear fashion along inclined-plane, two straight plate places, but under effect of inertia and upper end rainwash, flow down with camber line after allowing rainwater stop in arc, the rainwater causing to fall and break is farther apart from mechanism case, prevents from following the strong wind of heavy rain that rainwater is blown on mechanism case.On transverse slat on mechanism case, be also provided with the groove that runs through front and back sides, the built-in rectangle splash guard of groove, in the time of rainy day maintenance circuit breaker, can be further that chamber door place direction pulls by rectangle splash guard to mechanism case front panel direction, block above mechanism case chamber door, prevent that rainwater from tiltedly flying into mechanism case, and can keep off the rain for operating personnel.
As a further improvement on the present invention, described mechanism case both sides are also respectively provided with a fixed head, and fixed head upper end is fixedly connected with transverse slat, offers tapped through hole on fixed head, and it is fixed on the side of mechanism case by puller bolt.Because the present invention is mainly used in old mechanism case, therefore mechanism case can not do any improvement substantially, because the fixation of anchor ear is limited, water-tight device may roll under large wind effect, in order further to strengthen the stability of this water-tight device on mechanism case, this programme is set up two fixed heads, and two fixed heads lay respectively at the left and right side at mechanism case casing, be stuck in mechanism case both sides, prevent that water-tight device from rolling.
Further, the cross section of described arc plate on fore-and-aft direction is also curved, and the center of circle of this arc section upwards, mainly flows down rainwater from arc plate center, prevents that its both sides, front and back from spilling rainwater, drenches mechanism case.
Further, described transverse slat is rectangular slab, and its length and width are greater than respectively length and the width of mechanism case end face, makes transverse slat also can shelter from four edges of mechanism case top panel, further strengthens its waterproof effect.
Further, the angle that two straight plate upper ends form is 120 ° ~ 140 °, makes that rainwater is smooth and easy to be flowed down.
To sum up, the invention has the beneficial effects as follows:
1, the present invention can be used for circuit breaker mechanism case old-fashioned, that do not design waterproof outer, can prevent that rainwater from entering circuit breaker mechanism case;
2, the present invention has designed inverted V-shaped splash guard, the two-layer splash guard of transverse slat, and two lower ends of inverted V-shaped splash guard adopt arc design can make rainwater as far as possible away from mechanism case, have good waterproof effect;
3, the present invention has also designed rectangle splash guard, prevents that rainwater from tiltedly flying to fall into mechanism case from side, chamber door place, and can overhaul in the rainy day time for operating personnel are kept off the rain;
4, the present invention can stablize and is arranged on mechanism case upper end, good stability;
5, the present invention also can be applicable to be designed with the circuit breaker mechanism case of outer, highly versatile, in addition of the present invention simple in structure, easy for installation, cost is low.
