Abstract
The utility model discloses a kind of secondary cables to protect structure, including：Transducer bracket, secondary cable terminal box, steel pipe and anchor ear, wherein, secondary cable terminal box and anchor ear are both secured on transducer bracket, and anchor ear is located at the lower section of secondary cable terminal box, steel pipe is located in anchor ear vertically, and the lower part of secondary cable terminal box is stretched on the top of steel pipe.The structure of secondary cable protection structure is simple, it can be achieved that the fixation of steel pipe, avoids steel pipe from sinking, and secondary cable is prevented to be damaged due to steel pipe sinks.
Description
Technical field
The utility model is related to electrical equipment technical fields, specifically provide a kind of secondary cable protection structure.
Background technology
Mutual inductor is the general designation of current transformer and voltage transformer, can high voltage be become to low-voltage, high current becomes
Low current, for measuring or protecting system, while mutual inductor may further be used to separate high-voltage system, to ensure the person and equipment
Safety, is equipment indispensable in electric system.Due to northern weather etc., many substations are to install in winter, soil
Earth, which also has, freezes layer, and the secondary cable and steel pipe constructed at this time inevitably begin with the sign of sinking in the next spring, and the lighter will
By secondary cable insulation breakdown, severe one will appear ground connection, lead to the equipment damage even system failure.
Therefore, a kind of secondary cable protection structure is developed, to prevent secondary cable from being damaged due to steel pipe sinks, becomes people
Urgent problem to be solved.
Utility model content
In consideration of it, the purpose of this utility model is to provide a kind of secondary cables to protect structure, to solve secondary cable appearance
Easily cable insulation is led to problems such as to damage due to steel pipe sinks.
Technical solution provided by the utility model is：Secondary cable protects structure, including：Transducer bracket, secondary cable
Terminal box, steel pipe and anchor ear, wherein, secondary cable terminal box and anchor ear are both secured on transducer bracket, and anchor ear is located at secondary
The lower section of cable coupling box, steel pipe are located in anchor ear vertically, and the lower part of secondary cable terminal box is stretched on the top of steel pipe.
It is preferred that the anchor ear is welded on transducer bracket, insulation spacer is provided on the inside of the retaining part of anchor ear.
Further preferably, the insulation spacer is rubber sheet gasket.
Secondary cable provided by the utility model protects structure, by setting anchor ear on transducer bracket, can realize
Fixation to steel pipe, prevents steel pipe from sinking, and is not in because of steel after secondary cable is accessed by steel pipe in secondary cable terminal box
Pipe sinks and breaks down and the problem of accident, ensure that equipment safety, also ensure power grid security.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment is described in further detail the utility model：
Fig. 1 is the structure diagram that secondary cable protects structure.
Specific embodiment
The utility model is further explained, but do not limit to this practicality below in conjunction with specific embodiment
It is novel.
As shown in Figure 1, secondary cable protects structure, including：Transducer bracket 1, secondary cable terminal box 2, steel pipe 3 and embrace
Hoop 4, wherein, secondary cable terminal box 2 and anchor ear 4 are both secured on transducer bracket 1, and anchor ear 4 is located at secondary cable terminal box 2
Lower section, steel pipe 3 is located in vertically in anchor ear 4, and the lower part of secondary cable terminal box 2 is stretched on the top of steel pipe 3.
The secondary cable protects structure, by setting anchor ear on transducer bracket, can realize the fixation to steel pipe, prevents
Only steel pipe sinks, and is not in due to steel pipe sinks and occurs after secondary cable is accessed by steel pipe in secondary cable terminal box
The problem of barrier and accident, it ensure that equipment safety, also ensure power grid security.
In order to ensure the stabilization of anchor ear and fastener for connection, as the improvement of technical solution, the anchor ear 4 is welded in mutual inductor
On stent 1, insulation spacer is provided on the inside of the retaining part of anchor ear 4, wherein, the insulation spacer is rubber sheet gasket.
Specific embodiment of the present utility model is write according to progressive mode, highlights each embodiment party
The difference of case, similar portion can be with cross-reference.
The embodiment of the utility model is elaborated above in conjunction with attached drawing, but the utility model is not limited to
The above embodiment within the knowledge of a person skilled in the art, can also not depart from the utility model
Various changes can be made under the premise of objective.
