27.5kV be isolated on-load switch, be voltage rating 27.5kV, rated frequency 50Hz it is single-phase, two-phase alternating current height presses off Equipment, often referred to simply as on-load switch are closed, is using a kind of more electric appliance in electric railway electric appliance, for division load electricity Stream, no-load transformer and cable charging current assemble the on-load switch (with fuse) of earthing switch, can be with bearing load electricity Stream.Its arc quenching principle mainly has air pressing type and grid formula, and type of insulation uses air insulation;Mounting means using side-mounted, The 10kV and 35kV of such mounting means power grid use more (three-phase equipment), since its particularity requires it in electric railway Right angle setting or coplanar installation, on-load switch has, heat dissipation area is small for existing 27.5kV isolation, conductive and antiseptic property not The problems such as good, for this purpose, we have proposed a kind of indoor single isolation on-load switches of 27.5KV to come into operation, to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of indoor monopoles of 27.5KV, and on-load switch is isolated, to solve above-mentioned background The problem of being proposed in technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of indoor monopole isolation load of 27.5KV Switch, including chassis, present on the chassis in have three groups of supporting insulators, the top supporting insulator is equipped with touching Piece, the contact are equipped with arc-control device, and rotation is equipped with operator, two groups of lower section supporting insulator in the intermediate supporting insulator Between be equipped with fuse, the chassis is equipped with the main connecting lever of mechanism, and the bottom end of the main connecting lever of mechanism connect with insulated pull rod, institute The other end and operator for stating insulated pull rod are rotatablely connected, and the chassis is equipped with separating brake energy-stored spring.
Preferably, the chassis is equipped with earthing knife-switch, and earthing knife-switch passes through mechanism pull rod manual divide-shut brake, the operator and earthing knife-switch Between added with mechanical latching
Preferably, the outer wall of the contact is provided with silver coating, and the top of the contact is equipped with arc initiation device and interrupter cartridge It sets, the outside of the contact is equipped with spring.
Preferably, the chassis is equipped with quick-release mechanism, and quick-release mechanism and operator connect.
Compared with prior art, the utility model has the beneficial effects that by the main connecting lever of motor drive mechanism rotating mechanism, then lead to It crosses pull rod or shaft coupling is coupled isolation on-load switch main shaft, make divide-shut brake of operating;Its ram bounces after fuse blows, Quick-release mechanism movement makes separating brake of operating, and earthing knife-switch is operated between earthing knife-switch by mechanism pull rod manual divide-shut brake added with machine Tool locking;The outer wall of contact is provided with silver coating, top has striking and arc-control device, keeps contact heat dissipation area big, lead Electricity and Corrosion Protection are good, and spring leaf is provided on the outside of contact, deform that small service life is long, does not form galvanic circle, not by galvanic corrosion, Adjustable pressure, makes contact be in contact condition always, and contact friction stroke is short during division, operating force is small, has The characteristics of structure novel, high reliablity.
Detailed description of the invention
Fig. 1 is the utility model front view;
Fig. 2 is the utility model side view.
In figure: 1 chassis, 2 supporting insulators, 3 arc-control devices, 4 separating brake energy-stored springs, 5 fuses, 6 mechanism masters turn wall, 7 Insulated pull rod, 8 operators, 9 contacts.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of indoor monopole isolation load of 27.5KV is opened Close, including chassis 1, presented on the chassis 1 in have three groups of supporting insulators 2, the top supporting insulator 2 is equipped with Contact 9, the contact 9 are equipped with arc-control device 3, and rotation is equipped with operator 8, two groups of lower section branch in the intermediate supporting insulator 2 Support insulator 2 between be equipped with fuse 5, the chassis 1 be equipped with the main connecting lever 6 of mechanism, the bottom end of the main connecting lever 6 of mechanism and absolutely Edge pull rod 7 connects, and 8 rotation connection of the other end and operator of the insulated pull rod 7, the chassis 1 is equipped with separating brake energy-stored spring 4。
Wherein, the chassis 1 is equipped with earthing knife-switch, and earthing knife-switch is by mechanism pull rod manual divide-shut brake, convenient for the closure of earthing knife-switch, Added with mechanical latching between the operator 8 and earthing knife-switch, when faulty operation occurs, automatic blocking may be implemented, prevent mistake behaviour The progress of work, the outer wall of the contact 9 are provided with silver coating, and the top of the contact 9 is equipped with arc initiation device and arc-control device 3, Keep 9 heat dissipation area of contact big, conductive and Corrosion Protection is good, and the outside of the contact 9 is equipped with spring so that contact 9 deform it is small Service life is long, does not form galvanic circle, and not by galvanic corrosion, the chassis 1 is equipped with quick-release mechanism, and quick-release mechanism and master Knife 8 connects, convenient for the separating brake of operator 8.
