Description
Technical field
The utility model relates to a kind of central-positioned high-voltage switch cabinet current transformers to replace trolley.
Background technique
10 kilovolt middle-placed formula high-tension switch cabinets in substation using more and more extensive, but because of Current Mutual Inductance in switchgear
The reasons such as reserved capacity is insufficient when device designs or load growth is too fast cause current transformer ratio not to be able to satisfy actual load increasing
Long demand need to be replaced.
Currently, current transformer generally uses cable vault rear portion back dress or bus-bar room bottom lifting mode, tradition to make in cabinet
When industry, a people is needed to be held with hand, fixed current mutual inductor, people's fixed disassembly bolt also needs a people to pierce cable vault's cooperation
Dismounting inside fixing bolt.In addition, when the current transformer of replacement is different manufacturers, the parameters such as shape, installation pore size
It is different from original equipment, therefore before new current transformer installation need that new current transformer is repeatedly placed on installation site and compare
It is right, it is ensured that mounting process meets the requirements.But due to narrow space in switchgear, come to current transformer replacement work belt great
Inconvenience, one holds current transformer for a long time and carries out operation in a limited space, and labor intensity is very big.Meanwhile current transformer
Single device weight is easily fallen in disassembly process up to 45 kilograms, causes the person, equipment damage, has biggish safety
Risk.
To solve the above problems, Authorization Notice No. is the Chinese patent of CN204897312U, discloses and set in a kind of replacement
The trolley of cabinet flip-over type current transformer, including the fixation fork arm elevator apparatus between the support platform and pedestal of trolley, in institute
State hydraulic pump fixed on yoke lifting device, the lifting handle connecting with the hydraulic pump；It is hydraulic by lifting handle actuating
Pump driving yoke lifting device, controls the height of support platform, realizes the replacement to middle-placed switch cabinet flip-over type current transformer.This is small
Although vehicle may be implemented current transformer and flexibly move and go up and down, but have the following problems:
1, current transformer is mounted on central-positioned high-voltage switch cabinet upper inside, under the barrier effect of cabinet body wall, needs
Installation position could be risen to completely by being first placed in cabinet, and above-mentioned trolley needs to hold when protruding into cabinet body handle, rearward sticks up
Trolley is played, the current transformer in support platform could be fully recessed into cabinet body, since current transformer weighs 45 kilograms, and
Trolley itself has certain weight, and the process difficulty for tilting push-in is big, operating difficulties.
2, fixed disassembly bolt must by just can be carried out in staff's access switch cabinet, and above-mentioned trolley use yoke
Lifting device, though being able to achieve the automatic lifting of current transformer, structure is complicated, need to occupy support platform and trolley bottom it
Between space, the space that staff carries out operation in cabinet further decreases, and hinders larger, constructional difficulties.
Utility model content
The purpose of this utility model is to provide a kind of simple and quick, easy to use, high conducive to the middle of construction
The cabinet current transformer that compresses switch replaces trolley.
This central-positioned high-voltage switch cabinet current transformer provided by the utility model replaces trolley, including vehicle frame and support
Platform, the vehicle frame installs the idler wheel of stand rear end bottom and top by stand, respectively and handrail forms, the support platform water
Safety on stand is slid vertically mounted in stand front end and by hank dish driving.
The guide housing that the support platform is arranged by horizontally disposed support frame and vertically is vertically affixed to be formed, on stand top
Portion center is equipped with fixed pulley, and for the guide housing sliding sleeve between the side wall of stand, the strand cable of the capstan winch passes through fixed pulley
The support frame being connect on driving guide housing with guide housing slides vertically in stand.
Hangers is equipped with fixed pulley corresponding position at the top of the guide housing.
It is symmetrically arranged with the guide groove being vertically arranged in the inside sidewalls of the stand, is equipped on the side wall of the guide housing
Several pulleys with guide groove cooperation, the guide housing are slidably mounted in stand by pulley and guide groove cooperation.
To guarantee the bearing capacity of support platform and the sliding vertically property of guide housing, edge is equipped in the support frame rear end sides
The auxiliary wheel that guide groove outer wall slides vertically.
For that can automatically keep when guaranteeing heavy lift to the height needed, prevent support platform and current transformer from falling automatically
Under, the safety of effective guarantee staff, the capstan winch uses self-locking manual capstan winch.
For that can automatically keep when guaranteeing heavy lift to the height needed, prevent support platform and current transformer from falling automatically
Under, the safety of effective guarantee staff, the capstan winch uses self-locking electric capstan.
To make the utility model be suitable for special ground environment in substation and 10 kilovolts of hyperbaric chambers, have anti-skidding, durable
The characteristics of with complex road condition is adapted to, the idler wheel use rubber roll, which uses 10 cun to 15 cun rubber rolls.
For the stress for cooperating cabinet door, abuts against trolley on rear cabinet, be symmetrically arranged with two arcs in the stand bottom front
Top plate.
For convenience of the standing of the utility model, support plate is equipped in the support frame front bottom end.
Compared with prior art, the utility model has the advantage that
1, support platform is placed in vehicle frame front end and is gone up and down by winch control, can push directly on during support platform is placed in by vehicle frame
It sets inside formula high-tension switch cabinet, does not need artificial rear overturning body and current transformer, convenient transport are easy to operate；Trolley is in place
Afterwards, under the action of cabinet body bus-bar room rear cabinet door, vehicle frame leans on cabinet body standing and does not fall, and support platform is risen to peace by staff
The space of support platform bottom, fixed disassembly bolt can be entered after holding position, whole process does not need the fixed trolley of personnel, really
Maximization and the operation number for having protected working region are minimized, easy to operate.
2, self-locking after being shaken support platform to current transformer mounting height using capstan winch, it is mutual then can directly to dismount electric current
The fixing bolt of sensor.Whole process does not need additional increase personnel and goes to hold current transformer, and changing operating personnel needs to grow
Phase manually holds the traditional work method that current transformer is installed, and greatly reduces labor intensity；Avoid electric current mutual simultaneously
Sensor falls when replacing, collides with and cause the damage of personnel and equipment, further obviates security risk when operation.
The utility model is easy to operate, space occupied is small, suitable for complicated, narrow space operation field, can be shortened electricity
Current transformer replacing construction reduces construction labor intensity, it is ensured that the person and equipment safety in operation process；It can be used for constructing
The transport and auxiliary dismounting of the equipment such as Work tool, instrument and meter, 35 kilovoltage mutual inductors, current transformer, realize that a vehicle is more
Use function.
