Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figures 2 and 3, the utility model high-voltage switch cabinet door and earthed switch interlocking device, comprise cabinet, cabinet is provided with door, earthed switch, earthed switch operating axis is coaxially fixedly connected with cam 1, below cam 1, be provided with and be the L shaped blocking lever 2 that stands upside down, there is the path section 2.2 of one section of reduced the centre of blocking lever 2 vertical sections 2.1, described door is fixedly connected with a horizontal hyoplastron 3, support 4 is installed on cabinet, described support 4 is a case type rectangular frame, the top and bottom of support 4 have the circular hole of upper and lower correspondence, vertical section 2.1 of blocking lever 2 successively through horizontal hyoplastron 3 and support 4.One end of horizontal hyoplastron 3 is the U-shaped of horizontal positioned, and the other end has circular hole 3.1, and the edge of this circular hole 3.1 is formed with breach 3.2, as shown in Figure 4.The described blocking lever 2 vertically diameter of section 2.1 is less than circular hole 3.1 diameters on horizontal hyoplastron 3, and be greater than breach 3.2 width on horizontal hyoplastron 3, the diameter of the path section 2.2 of blocking lever 2 is less than breach 3.2 width of horizontal hyoplastron 3, on vertical section 2.1 of described blocking lever 2, be fixed with a Horizontal limiting pin 5, between Horizontal limiting pin 5 and support 4, be provided with back-moving spring 6, described Horizontal limiting pin 5 and back-moving spring 6 are all arranged on the inside of support 4.
Described high-voltage switch cabinet door and earthed switch interlocking device also comprise that driving blocking lever makes blocking lever path be positioned at the drive unit of hyoplastron indentation, there, described drive unit comprises fixed cover 7, pin 8 and release lever 10, described fixed cover 7 is linked in the vertically end of section 2.1 of blocking lever 2, and be fixed on blocking lever 2, described pin 8 is fixed on cabinet, described release lever 10 is hinged on blocking lever 2 lower ends by swivel pin 9.1, described 8 close release levers 10 of pin, and be positioned at 1/3rd places of release lever 10 near swivel pin 9.1 one end, when blocking lever 2 path sections 2.2 are positioned at hyoplastron 3 breach 3.2 place, the axis of described pin 8 and the axis of swivel pin 9.1 are in the same horizontal line, release lever 10 can rotate around pin 8, described release lever 10 one end are rotatably fixed on fixed cover 7, the other end is through the slotted hole on cabinet body door.
When high-tension apparatus catastrophic failure, and now earthed switch cannot close a floodgate, blocking lever 2 is at the highest notch under the effect of back-moving spring 6, vertical section 2.1 of blocking lever 2 in the circular hole 3.1 of horizontal hyoplastron 3, the path section 2.2 of blocking lever 2 is above horizontal hyoplastron 3, and because vertical section of 2.1 diameters of blocking lever 2 are greater than the width of horizontal tongue version breach 3.2, blocking lever 2 cannot be deviate from from the breach of horizontal hyoplastron 3 3.2, horizontal hyoplastron 3 is fixedly connected with door again, so door cannot be opened.Now need to use emergency unlocking device, upwards lift release lever 10 and be positioned at one end of slotted hole outside, because release lever 10 can rotate around pin 8, and pin 8 is fixed on cabinet, due to leverage, one end that release lever 10 is connected with fixed cover 7 drives blocking lever 2 to move downward, when the path section 2.2 of blocking lever 2 is positioned at the circular hole 3.1 of horizontal hyoplastron 3, because the diameter of path section 2.2 is less than the width of circular hole 3.1 emargintions 3.2, now horizontal hyoplastron 3 can move horizontally, cabinet body door just can be opened, as shown in Figure 3, be convenient to equipment to carry out on-call maintenance.
With regard to the utility model preferred embodiment, be described above, but can not be interpreted as it is limitations on claims.This practicality is carried out and is not only confined to above embodiment, and its concrete structure allows to change, as: pin can be positioned at optional position on release lever; When blocking lever path section is positioned at hyoplastron indentation, there, not in the same horizontal line etc., all various variations of doing in the protection range of the utility model demand for independence are all in protection range of the present utility model for the axis of pin and the axis of swivel pin.
