Description
Technical field
The utility model belongs to electric power system power plant or transformer station's main equipment technical field, relates to voltage transformer (PT) cabinet of the new structure that a kind of security performance and Practical Performance are higher.
Background technology
The conventional voltage transformer cabinet unreasonable structure of electric power system at present, security performance is not high, go wrong frequently, main manifestations is: it is not to place separate unit PT that a PT cabinet is placed, many group PT cause the enabling capabilities of PT cabinet design inadequate, often occur the distortion of PT cabinet, the bottom out-of-flatness of PT cabinet, while easily causing PT operation, be obstructed, be difficult for pull-out or advance; Joint adopts duck-beak type structure, designs unreasonablely, and contact-making surface is less, often occurs overheated spark phenomenon; PT adopts direct push-in type, in use often goes wrong, and exerts oneself contact little bad, the excessive contact of worrying again to damage of exerting oneself.
Therefore, need to, from changing the structure angle of voltage transformer (PT) cabinet, need in conjunction with onsite user, carry out serious analysis and research, by brand-new design concept, try to explore to make security performance and Practical Performance to arrive the PT cabinet of mutually unified new structure.
Summary of the invention
The purpose of this utility model is the unreasonable structure that the voltage transformer conventional for current electric power system (PT) cabinet exists, security performance is not high, the problem such as go wrong frequently, has proposed voltage transformer (PT) cabinet of the new structure that a kind of security performance and Practical Performance are higher.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of voltage transformer cabinet is installed a voltage transformer in a cabinet; Comprise cabinet and be arranged on cabinet inner rocker arm pull-out type dolly, voltage transformer, high-tension fuse and insulator; Described voltage transformer and insulator are arranged on rocking arm pull-out type dolly; Quincunx dynamic/static contact is installed in the upper end of described insulator, and one end of described quincunx dynamic/static contact is connected with voltage transformer by high-tension fuse, and the other end contacts with copper bar; The base plate of described cabinet is provided with travel switch and heating plate; The madial wall of described cabinet is provided with a greenhouse controller.
Voltage transformer of the present utility model (PT) cabinet, by current conventional PT cabinet is transformed, makes to install in 1 cabinet 1 PT into by two PT are installed in 1 cabinet of common PT cabinet, and cabinet board thickness is increased; Make traditional Duckbilled contact into quincunx contact; Use rocking handle to shake into formula structure direct push-in type structure instead.After transformation, structure is more reasonable, and security performance promotes greatly.
Make to install in 1 cabinet 1 PT into by two PT are installed in 1 cabinet of common PT cabinet, and cabinet board thickness is increased, indeformable to guarantee PT cabinet, the evenness of PT bottom is met the demands, PT turnover is not subject to any stopping.
The utility model makes traditional Duckbilled contact into quincunx contact, has avoided duck-beak type structural design unreasonable, and contact-making surface is less, often occurs overheated spark phenomenon, and improved plum blossom fingertip contact is better, does not generate heat, and does not strike sparks.
The utility model is arranged on voltage transformer (PT) on rocking arm pull-out type dolly; PT is passed in and out to mode uses rocking handle to shake into formula structure by direct push-in type structure instead, avoid the problem often occurring in direct push-in type use, it is bad to exert oneself contact little, the excessive worry again of exerting oneself is damaged contact, after transformation, slowly shake into, guaranteed that contact is good, can not damage again contact.
Above-described rocking arm pull-out type dolly is provided with blocking mechanism.
The top board outside of above-described cabinet is also provided with one end seed cell.
The sheet metal thickness of the above cabinet is more than 3mm.
On cabinet front side board of the present utility model, be also provided with charged indicator light and illuminating lamp; In cabinet, be also provided with illuminating lamp travel switch, aviation plug, indicator light and insulating barrier put in place.
Described voltage transformer and copper bar adopt insulating barrier to separate; On insulating barrier, be provided with through hole, quincunx dynamic/static contact contacts with copper bar by through hole.
In the utility model, a set of voltage transformer cabinet has 7 cabinets, two cabinets of every phase, then add a terminal cabinet.
Compared with prior art, the beneficial effect that the utility model possesses:
(1) the utility model is by making into, in 1 cabinet, 1 PT is installed by two PT are installed in 1 cabinet of common PT cabinet, improved PT cabinet turnover mode simultaneously, greatly aspect Field Force's operation, operating efficiency is provided.
(2) the utility model makes traditional Duckbilled contact into quincunx contact, has greatly improved the contact performance of contact, has improved the security performance of equipment.
