FIG. 1
The utility model relates to the field of electrical test technologies, and in
particular, to an electrical test box for a substation.
Substations are places where voltage is transformed. To transmit electrical
energy from power plants to far places, voltage of the electrical energy must be
stepped up to high voltage, and then the high voltage is stepped down as needed for
users. Voltage step-up and step-down depends on the substations. Main equipment of
the substations is a switch and a transformer. By size, small substations are referred to
as switching stations, and the substations are larger than the switching stations. The
switching stations are generally step-down substations with a voltage level less than
110 kV, whereas the substations include "step-up and step-down" substations of
various voltage levels.
Doors of existing electrical test boxes are inconvenient to open for inspection
and maintenance. In addition, some existing test boxes are troublesome to use because
of a complex structure, and a temperature rise in the test box affects a service life of a
box body. Therefore, an electrical test box for a substation is proposed to resolve the
foregoing problems.
An electrical test box for a substation is proposed to implement the objective of
the utility model of resolving a prior-art problem that an inspection door of an
installation box is inconvenient to open.

Referring to FIG. 1 to FIG. 3, an electrical test box for a substation is provided,
including a box body 1, two first vertical rods 2, two second vertical rods 3, and an
inspection door 4, where both the two second vertical rods 3 are fixedly connected to
a lower part of the inspection door, both the two first vertical rods 2 are fixedly
connected to the box body 1, locations at which both the two first vertical rods 2 are
fixedly connected to the box body 1 are below locations at which both the two second
vertical rods 3 are fixedly connected to the lower part of the inspection door, both
ends of a second vertical rod 3 are fixedly connected to a first connecting block 5 and
a second connecting block 6, the first connecting block 5 is rotatably connected to a
first connecting rod 7, one end of the first connecting rod 7 is rotatably connected to a
curved rod 9, the first connecting block 5 is rotatably connected to a second
connecting rod 8, one end of the second connecting rod 8 is rotatably connected to a
middle part of the curved rod 9, the middle part of the curved rod 9 is rotatably
connected to a third connecting rod 10, one end of the curved rod 9 away from the
first connecting rod 7 is rotatably connected to a fourth connecting rod 11, both ends
of a first vertical rod are fixedly connected to a third connecting block 13 and a fourth
connecting block 14, the third connecting rod 10 is rotatably connected to the third
connecting block 13, and the fourth connecting rod 11 is rotatably connected to the
fourth connecting block 14. The utility model is simple in structure and convenient to
use. The provided two ventilation windows 18 can implement natural flow and
dissipation of heat generated by electrical components in the box body 1 in a working
process, thereby prolonging a service life of the box body 1.
The fourth connecting block 14 is fixedly connected to a spring 12, and one end
of the spring 12 is fixedly connected to the middle part of the curved rod 9. Under a pushing force of the spring 12, the closed inspection door 4 does not open easily if there is no external force.
Both sides of an upper part of the inspection door are fixedly connected to a third
vertical rod 19, both sides of the box body 1 are fixedly connected to a fourth vertical
rod 20 in cooperation with the third vertical rod 19, the third vertical rod 19 isfixedly
connected to a horizontal block 17, the horizontal block 17 is rotatably connected to
an elliptical ring 15, and the fourth vertical rod 20 is fixedly connected to a gear rod
16 in cooperation with the elliptical ring 15. This allows the inspection door 4 to be
more firmly closed.
An observation hole is provided in a middle part of the inspection door 4, and
transparent glass is provided for the observation hole. This is convenient for the staff
to observe the box body 1 in a using process.
Two ventilation windows 18 are provided in the box body 1 and are
symmetrically located on two sides of the inspection door 4. The provided two
ventilation windows 18 can implement natural flow and dissipation of heat generated
by electrical components in the box body 1 in a working process.
A wear layer is provided at a location at which the second connecting rod 8 and
the third connecting rod 10 are connected to the curved rod 9. This increases usage
time, and prolongs the service life of the box body 1.
In the utility model, the box body 1 needs to be opened for maintenance, the
elliptical ring 15 at the upper part of the inspection door 4 is lifted up to make an
upper part of the elliptical ring 15 higher than an upper part of the gear rod and drive
the inspection door, so that the first connecting block 5 drives the first connecting rod
7 to move in a direction to which the inspection door 4 is driven, thefirst connecting
rod 7 drives a joint of the curved rod 9 with the first connecting rod 7 to move, the
second contact block drives the second connecting rod 8 to move in the direction to
which the inspection door 4 is driven, the second connecting rod 8 presses against the
middle part of the curved rod 9 to compress the spring 12, the third contact block
drives the third connecting rod 10 to rotate in the direction to which the inspection
door 4 is driven, and the curved rod 9 drives the fourth connecting rod 11 to rotate in the direction to which the inspection door 4 is driven. The fourth connecting rod 11 has a turning point at the fourth contact block. When the third connecting rod 10 and the fourth connecting rod 11 are in a horizontal position, the inspection door 4 is fully opened. In this case, it is convenient for the staff to repair and check the box body 1.
Because the spring 12 is compressed, the inspection door 4 needs to be closed. When
the inspection door 4 is pushed, the middle part of the curved rod 9 is pushed under a
rebound force of the spring 12, thereby saving efforts of a user to close the inspection
door 4. The utility model is simple in structure and convenient to use. The provided
two ventilation windows 18 can implement natural flow and dissipation of heat
generated by electrical components in the box body 1 in a working process, thereby
prolonging the service life of the box body 1.

utility model, but the protection scope of the utility model is not limited thereto. Any
equivalent replacements and modifications made by a technical person familiar with
the art according to the technical solutions and the new utility concepts of the utility
model within the technical scope disclosed in the utility model shall fall within the
