Description
Technical field
The utility model belongs to the electric switchgear field, relates in particular to a kind of special maintenance device that is used for handcart type breaker.
Background technology
Circuit breaker not only can cut-off and the normal load operating current is closed in the pass, can also cut-off and rated short circuit current is closed in the pass, and therefore, circuit breaker is commonly used to cooperate excision fault loop overload or short circuit current automatically with element such as relay.
3AH type vacuum circuit-breaker (hereinafter to be referred as handcart type breaker) belongs to open type air insulation vacuum circuit-breaker product, and it obtains widely applying in each transformer station that the applicant belongs to electric company.
So in the actual operation power course of work, the regular maintenance of such handcart type breaker, maintenance or testing amount are bigger, what needs were regular carries out corresponding regular maintenance, maintenance or detection to it according to plan.
Existing 3AH type handcart type breaker carries out " from cabinet " (in switch cubicle, haul out, be commonly called as from cabinet) when safeguarding at needs to it; Can only be earlier along the sliding rail in the switch cabinet; Handcart type breaker is hauled out to come from switch cubicle, again it is moved to and safeguard vacant lot or safeguard that the place carries out related work, because due to its switch mechanical structure; When it is carried out regular maintenance or service work; Can only place it in the enterprising line correlation work in ground, the operating personnel need lie prone or couchantly carry out operation, very inconvenience.
Adopt this mode to carry out maintenance work; The one, harmful to this body structure of breaker apparatus; And be not easy to the associated components of its bottom is overhauled, safeguards; The 2nd, when needs carry out various electrical tests (such as withstand voltage test etc.) to whole handcart type breaker, the direct placement of handcart type breaker can't be carried out on the ground, and satisfied/Pass Test, the requirement of electrical distance over the ground in the safety regulations.
For above-mentioned reasons; Sometimes on-the-spot operation, testing crew also can be placed on a wooden chair or the enterprising line correlation work of stool with handcart type breaker; But such one is that the lifting surface area of chair or stool is quite little; It is insecure that handcart type breaker is placed, and the danger of toppling is arranged, the 2nd, still easily the associated components of rival car formula circuit breaker bottom overhaul, maintenance work.
Generally speaking, the maintenance of a conventional 10KV switch disconnector only needs 3 manual works to carry out/to accomplish; But 3AH type handcart type breaker is safeguarded; Must 4 manual works can carry out, 1 manual work that has more will be unloaded switch from the delivery dolly; And in maintenance process, help the handcart-type killer switch, do not topple with protection switch.
So the type circuit breaker particular structural makes when the actual field service work, will expend more manpower and materials compared with general circuit breaker, and also very inconvenience of the operation of personnel when maintenance, also there is bigger potential safety hazard when safeguarding.
The utility model content
The utility model technical problem to be solved provides a kind of 3AH type handcart type breaker special maintenance platform; It adopts a cabinet type double-deck maintenance platform special, that have the rectangle service hatch to place handcart type breaker to be repaiied; Both solved and waited to repair handcart type breaker and place stable/firm problem; Overhaul, safeguard and provide convenience for associated components again the circuit breaker bottom; Also can make and wait that the place to place of repairing handcart type breaker satisfy/meets the requirement of electrical distance over the ground in the electrical test safety, greatly alleviate field operation personnel's labour intensity, improve operating efficiency; Shorten the repair time, and then helped to improve the operation effective time and the online power-on time of equipment of whole transformer station.
The technical scheme of the utility model is: a kind of 3AH type handcart type breaker special maintenance platform is provided, it is characterized in that: be provided with one by rectangle upper plate, rectangle lower shoe and four maintenance platforms that support post constitutes; Its described four support posts are fixed on four arms of angle of rectangle upper plate and rectangle lower shoe, and upper plate and lower shoe is spaced apart abreast, constitute a cabinet body maintenance platform; Below the rectangle upper plate, two reinforcements are set; At the upper surface of rectangle upper plate, an insulating blanket is set; At the medium position of rectangle upper plate and insulating blanket, offer a rectangle manhole; At four arms of angle of rectangle lower shoe bottom, correspondence is provided with four pulleys respectively.
Concrete, the transverse width dimension of said rectangle upper plate is greater than the transverse width dimension of rectangle lower shoe.
Further, in the both sides of said cabinet body maintenance platform, between rectangle upper plate and the rectangle lower shoe, be provided with the side shrouding.
Its described reinforcement is " U " type reinforcement.
At least two pulleys in its said four pulleys are for having the universal wheel of brake structure.
Compare with prior art, the utility model has the advantages that:
1. adopt movably the cabinet structure maintenance platform to place handcart type breaker to be repaiied, the equipment that both guaranteed is placed firm, can guarantee again to wait that the place to place of repairing handcart type breaker meets the requirement of electrical distance over the ground in the electrical test safety;
2. the rectangle manhole is set, for the associated components to the circuit breaker bottom overhauls, safeguards and provide convenience;
3. the operating personnel need not to lie prone again or couchantly carries out operation, and labour intensity alleviates greatly;
4. the repair time has been shortened in the raising of operating efficiency, and then helps to improve the operation effective time and the online power-on time of equipment of whole transformer station.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Among Fig. 1, the utility model discloses a kind of 3AH type handcart type breaker special maintenance platform, its concrete structure is: be provided with one by rectangle upper plate 1, rectangle lower shoe 2 and four maintenance platforms that support post 3 constitutes; Its described four support posts are fixed on four arms of angle of rectangle upper plate and rectangle lower shoe, and upper plate and lower shoe is spaced apart abreast, constitute a cabinet body maintenance platform; Below the rectangle upper plate, two reinforcements 4 are set; At the upper surface of rectangle upper plate, an insulating blanket 5 is set; At the medium position of rectangle upper plate and insulating blanket, offer a rectangle manhole 6; At four arms of angle of rectangle lower shoe bottom, correspondence is provided with four pulleys 7 respectively.
