Abstract
The utility model discloses a body contact protecting device for a transformer, which comprises a grounded bolt and a current transformer support which are arranged on an oil tank body. A current transformer is arranged on the current transformer support, a grounded cable is arranged on the grounded bolt and penetrates through the current transformer to be communicated with a grounded net, a whole steel plate is arranged on the bottom of the oil tank body to be a base, the edges of the base extrude out of the oil tank body, a tank bottom insulating plate is arranged under a tank bottom correspondingly and on a foundation precast steel plate. A foundation fixing plate is welded on the foundation precast steel plate, an insulating block is arranged between the foundation fixing plate and the base, used for compacting the base, fixing the tank body and enabling insulation between the tank body and ground. The body contact protecting device is an improvement of a body contact protecting structure, so that installation is led to be firm, and potential safety hazards and effects of the transformer on a power supply network caused by the fact that the tank body is electrified are avoided.
Description
Technical field:
The utility model design relates to technical field of transformer manufacturing, is specially a kind of transformer and bumps the shell protective device, strengthens the protection to transformer, converting equipment and staff.
Background technology:
At present, domestic transformer generally adopts oil immersed type, and casing band base, base are channel-section steel, and integral body directly is installed on the ground, also has special earth stud directly to insert ground network on the transformer-cabinet.In case it is charged to hinder transformer-cabinet for some reason, not only impacting of power supply network gone back the entail dangers to personal safety.
The utility model content:
The technical problems to be solved in the utility model provides a kind of transformer and bumps the shell protective device; it bumps the modifying device of shell protection for transformer; feasible installation is more firm, prevent simultaneously that transformer from causing because of casing is charged to the influence of power supply network and the potential safety hazard of bringing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of transformer bumps the shell protective device, comprise the current transformer support that is provided with on the earth stud that is arranged on the fuel tank casing, the fuel tank casing, current transformer is set on the support, the earth cable that is provided with on the earth stud, the through current instrument transformer communicates with ground network, and it is base that the fuel tank bottom half is provided with whole steel plate, and base edge protrudes in the fuel tank casing, face is provided with insulation board at the bottom of the case under the corresponding case, is arranged on the ground pre-embedded steel slab; Welding ground fixed head on the ground pre-embedded steel slab; Between ground fixed head and the base cross-over block is set, is used to compress base, static housing, and make casing and ground insulation.
Fixedly install under the ground fixed head and be the L shaped shape steel plate of increase with the ground adhesion.
Good effect of the present utility model is: transformer-cabinet adopts all insulation mounting means when design; transformer-cabinet is cancelled at the bottom of traditional channel-section steel case; and at the bottom of adopting whole steel plate as case; and and the earth between increase an insulation board; the fuel tank casing is isolated with the earth fully, set up current transformer on the casing, and pass ground connection behind the instrument transformer by earth stud connection earth cable on the casing; once casing is charged, protection is work at once.
Adopted reinforced fixed form, pre-buried 8 block plates of ground compress at the bottom of the case after welding with 8 L shaped steel plates and ground.
Description of drawings:
Fig. 1, a kind of transformer of the utility model bump shell protective device structure chart.
Embodiment:
A kind of transformer as shown in Figure 1 bumps the shell protective device, comprise the current transformer support 3 that is provided with on the earth stud 2 that is arranged on the fuel tank casing 1, the fuel tank casing 1, current transformer 4 is set on the support, the earth cable 5 that is provided with on the earth stud 2, through current instrument transformer 4 communicates with ground network, and it is base 6 that fuel tank casing 1 bottom is provided with whole steel plate, and base 6 edges protrude in fuel tank casing 1, insulation board 7 at the bottom of the case is set below 6 at the bottom of the corresponding case, is arranged on the ground pre-embedded steel slab 8; Ground pre-embedded steel slab (8) is gone up welding ground fixed head (9); Between ground fixed head (9) and the base (6) cross-over block (10) is set, is used to compress base, static housing, and make casing and ground insulation.
