Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model safety interlocking timer is elaborated.
In order to allow the utility model easy to understand, some directivity terms in this instructions, have been used.It should be noted that; the directivity term of mentioning in this instructions, such as " on ", D score, " left side ", " right side " etc., be the direction with reference to accompanying drawing; the directivity term using is in order to illustrate and to understand the utility model, but not in order to limit protection domain of the present utility model.
Referring to accompanying drawing 1 to 4, the housing 1 of safety interlocking timer is rectangular structure, and its top is locking closure 2, housing 1 can adopt to be renovated or the structure of cover-closing type, after whole device installation, housing 1 is fastening is arranged to an integral body, can be fixed or is directly welded and fixed by screw.In housing 1 outer side edges, by arranging portable, conveniently lift this device.
In housing 1, pass through slide mechanism setting program plate 3, program board 3 aluminium alloy materials, program board 3 is parallel with locking closure 2, and slide mechanism makes program board 3 realize and sliding in a direction.The structure of slide mechanism can adopt various forms of the prior art, and such as the dual-side at housing 1 arranges chute, the dual-side of program board 3 is being embedded in chute.In the drawings, slide mechanism comprises four slide bars 4 on the angle that is arranged on program board 2 both sides and is arranged on four upper sliding sleeves 5 in housing 1, each slide bar 4 penetrates in a sliding sleeve, and making slide bar 4 reserve the stroke space that enough program board 3 are slided, the glide direction of program board 3 is for being set to the length direction of housing 1.
On the locking closure 2 of housing 1, be provided with an inlet wire lock 6 and at least two outlet locks, the quantity of outlet lock determines according to the quantity of disconnector or grounding switch, the quantity of outlet lock or select 2,3,6 etc., three outlets lock of take here in scheming describes as example, three outlet locks in figure are respectively the first outlet lock 7, second and pay the bill to lock the 8 and the 3rd outlet lock 9, inlet wire lock 6 and outlet lock are bar lock, the core below of bar lock has vertical eccentric finger 10, and each finger 10 is connected to each core by a jam plate 11 separately.Inlet wire lock 6 and described each outlet lock all just can be extracted key when locking.First outlet lock the 7, second outlet lock the 8 and the 3rd outlet lock 9 glide directions along program board 3 are arranged, and inlet wire lock 6 is arranged on a side of three outlet lock lines, and has a spacing between the line of three outlet locks.
Position corresponding to inlet wire lock 6 in program board 3 arranges a playground type slotted hole, it is the first slotted hole 12, the first slotted hole 12 is at inlet wire lock 6 on the lock core center and the line between the center of finger during in released state, the first slotted hole 12 is vertical with the glide direction of program board 3, its width is slightly larger than the diameter of finger 3, guarantees that finger 3 can move in the first slotted hole.
Position corresponding to the first outlet lock 7 in program board 3 arranges a playground type slotted hole, it is the second slotted hole 13, the second slotted hole 13 is at the first outlet lock 7 on the lock core center and the line between the center of finger during in released state, and the second slotted hole 13 is parallel with the glide direction of program board 3.The first outlet lock 7 during from released state to blocking the movement locus of finger be 90 degree arcs, in program board 3, corresponding to the position of this 90 degree arc, offer an arcuate socket 14, arcuate socket 14 is connected with the second slotted hole 13, the width of arcuate socket 14 equates with the width of the second slotted hole 13, is all slightly larger than the diameter of finger.In program board 3, corresponding to the second outlet lock the 8 and the 3rd outlet lock 9, arcuate socket 14 and the second slotted hole 13 separately is also set, its setting position and parameter are identical with the first outlet lock 7.
After housing 1 installation, the finger 10 of inlet wire lock 6 penetrates in the first slotted hole 12, and the finger 10 of each outlet lock penetrates in each self-corresponding second slotted hole 13 or arcuate socket 14.
When carriage will meet inlet wire lock 6 from released state to blocking or from blocking to released state, the sliding space of program board 3 is enough.
Disconnector when this device transfers inspecting state for the voltage switchgear middle high-pressure primary system of generating plant, electric substation, distribution substation to from running status and while transferring running status to from inspecting state, the safety interlocking of grounding switch operation.
With primary system, operate the course of work of bright device for instance below, the key of the inlet wire lock of this device mates with feed isolating switch, the key of each outlet lock mates separately with outlet disconnector, a bus You Yi road feed isolating switch, three tunnel outlet disconnectores, respectively corresponding inlet wire lock and three outlet locks.
According to electrical standard, when each road possesses isolator operation condition, sub-switching operation program is: first disconnect after three tunnel outlet disconnectores, just allow to disconnect feed isolating switch; Closing operation program is: first close after feed isolating switch, three tunnel outlet disconnectores just allow to close successively.
After the first outlet is locked, the second outlet is locked and the 3rd outlet lock all injects key and all releases put in place, the finger of three outlet locks is all positioned at the junction of arcuate socket and the second slotted hole, at this moment, inlet wire lock turns to locking position from separating lock-bit, the finger of inlet wire lock moves in the first slotted hole, promote program board simultaneously and move downward, because the finger of three outlets lock is positioned at the upper end of the second slotted hole, moving upward of program board produced and hindered.
When any one in the first outlet lock, the second outlet lock and the 3rd outlet lock do not separated pin and put in place, inlet wire lock just cannot locking, and in the time of the key of three outlets locks all will being positioned to outlet lock, the key that inlet wire is locked just can be extracted.When the key of three outlet locks has one to extract from outlet lock, the key of inlet wire lock just cannot be extracted.
When inlet wire is locked in blocking, while extracting inlet wire lock key, because program board cannot horizontally slip, three outlets locks are all in released state, and three all cannot extract outlet lock key.
This device can be crossed work ticket system and manage, and electrician is operated and meet electric work standard completely, has improved job security.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
