Description
Technical Field
The utility model relates to a cubical switchboard field, especially a cubical switchboard zero sequence transformer fixed bolster.
Background
The switch cabinet is an electrical device and mainly used for opening, closing, controlling and protecting the electrical device in the process of generating, transmitting, distributing and converting electric energy of an electric power system. The zero sequence mutual inductor is assembled in a switch cabinet, and is matched with a relay protection device or a signal for use when a power system generates zero sequence grounding current, so that the action of elements of the device is protected or monitored. When electric shock or electric leakage fault occurs in the circuit, the secondary side of the mutual inductor outputs zero sequence current, so that equipment on the connected secondary line is protected to act, such as power supply cut-off, alarm and the like. Zero sequence transformers are used to detect unbalanced currents in a main circuit loop passing through the transformer, and generally need to be assembled on a bottom plate of a switch cabinet and need to be fixed by a reliable bracket. However, some manufacturers only fix the zero sequence transformer in the switch cabinet by using bolts, and do not design a bracket which is firm enough, so that the zero sequence transformer is fixed and easily shifts in position in the long-term use process of the switch cabinet, thereby causing protection failure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a cubical switchboard zero sequence transformer fixed bolster that structural stability is good, it includes a horizontal part and a vertical portion, the both ends of the said horizontal part can be set firmly on the cubical switchboard, the said vertical portion is perpendicular to the horizontal part and sets up; the vertical part is connected with a supporting sheet, one side of the supporting sheet is connected with the vertical part, the other side of the supporting sheet is connected with or abutted against the horizontal part, the vertical part is provided with a bolt hole for fixing the zero sequence transformer, and the zero sequence transformer can be fixedly arranged on one side of the vertical part, facing the supporting sheet, through the bolt hole.
Further, this fixed bolster is sheet metal component integrated into one piece.
Further, the backing sheet is as an organic whole with vertical portion, and backing sheet quantity is 2, is located the both ends of vertical portion respectively, and the backing sheet is that the tip of vertical portion carries out bending forming, and the backing sheet perpendicular to vertical portion.
Further, the support piece vertically abuts against the horizontal portion.
Furthermore, the two ends of the horizontal part are provided with fixing holes which are long-strip-shaped.
Further, the horizontal part and the vertical part are formed by bending.
Furthermore, one end of the horizontal part, which is far away from the vertical part, is reversely bent to form a first reinforcing rib.
Furthermore, a second reinforcing rib is reversely bent at one end of the vertical part, which is far away from the horizontal part.
Compared with the prior art, the utility model, this kind of cubical switchboard zero sequence transformer fixed bolster has following advantage:
1. simple structure, the processing cost is low, but structural stability is good, can guarantee in the permanent use of cubical switchboard, zero sequence transformer fixed position is stable, does not squint for zero sequence transformer exerts its guard action better.
2. The zero sequence transformer is fixedly arranged on one side of the vertical part, facing the supporting sheet, through the bolt holes, the fixing support is under the action of gravity of the transformer, the supporting sheet abuts against the horizontal part to enable the vertical part not to deform, and therefore the mutual inductor is more firmly fixed.
