Description

Technical Field

[0001] The utility model relates to an electrical cabinet and a box-type transformer vehicle comprising the electrical cabinet, and more specifically, to an electrical cabinet with a cable room door suitable for a cable quick-plug connector and an interlocking component thereof and a corresponding box-type transformer vehicle. Background Art

[0002] The box-type transformer vehicle uses the electrical cabinet in it to provide portable power to provide backup power for important facilities. In the prior art, the cables are connected from the bottom of the electrical cabinet, which inevitably requires space for wiring at the bottom of the electrical cabinet, making the electrical cabinet larger in size and also causing the center of gravity of the electrical cabinet to be higher, which is not conducive to the stability of the box-type transformer vehicle.

[0003] To this end, it is desired to propose an electrical cabinet and a box-type transformer to improve the defects in the prior art. Utility Model Content

[0004] According to a first aspect of the utility model, an electrical cabinet is proposed, comprising: a cabinet body, comprising an operating surface, the operating surface being arranged to be perpendicular to a horizontal plane, the cabinet body at least partially enclosing an internal space, the operating surface having an operating port, and a cable extending from the interior of the electrical cabinet via the operating port; a door panel assembly, arranged on the operating surface, the door panel assembly being movable between a first position and a second position relative to the cabinet body, when the door panel assembly is in the first position, the door panel assembly is positioned at the operating port, and when the door panel assembly is in the second position, the door panel assembly is positioned outside the operating port; a grounding switch assembly, comprising a grounding switch and an opening, the opening being arranged on the cabinet body, the grounding switch being configured to be operated via the opening to switch between a first state and a second state, when the grounding switch is in the first state, the electrical cabinet is not grounded, and when the grounding switch is in the second state, the electrical cabinet is grounded; wherein the electrical cabinet further comprises an interlocking assembly, the interlocking assembly being configured such that when the door panel assembly is in the first position, the opening is not closed, and when the door panel assembly is in the second position, the opening is closed.

[0005] According to this solution, the cable access position is changed from the bottom of the electrical cabinet to the vertical surface of the electrical cabinet, so that there is no need to set up a special space for the cable to pass through at the bottom of the electrical cabinet, which makes the electrical cabinet smaller and the center of gravity of the electrical cabinet more stable. At the same time, because the cable access position is changed from the bottom of the electrical cabinet to the vertical surface of the electrical cabinet, the possibility of electric shock caused by the operator mistakenly entering the electrical cabinet when the door panel is open is greatly increased. For this purpose, an interlocking assembly is also provided, which makes the grounding switch unable to be operated to switch the state (that is, keep the closed state to provide the grounding function) when the door panel is open, so that the switch cabinet is in the grounding state to avoid the occurrence of electric shock accidents; and the grounding switch can only be operated to switch the state when the door panel is closed.

[0006] In some embodiments, the interlock assembly may include a switch baffle, and when the door panel assembly is in the first position, the opening is not closed by the switch baffle, and when the door panel assembly is in the second position, the opening is closed by the switch baffle.

[0007] In some embodiments, the interlock assembly may further include a connecting rod and a stop pin, wherein the connecting rod is configured to move linearly, the stop pin is configured to move rotationally along an axis, movement of the door panel assembly can actuate the stop pin to rotate, rotation of the stop pin can actuate the connecting rod to move, and the switch baffle is fixed to the connecting rod.

[0008] In some solutions, the interlock assembly may further include a return spring, which biases the stop pin so that the switch baffle is biased to a position closing the opening.

[0009] According to this solution, when the door panel is moved out of the cabinet, the return spring provides a biasing force to the stop pin, and the switch baffle is then maintained in the position of closing the opening through the interlocking assembly, so that the grounding switch cannot be operated to switch the state (i.e., remain in the closed state to provide the grounding function).

[0010] In some solutions, the door panel assembly may include a door panel body and a clamping plate. When the door panel assembly is in the first position, the clamping plate is assembled to the door panel body, and the clamping plate cooperates with the door panel body to form a circular opening for the cable to extend out.

[0011] In some embodiments, the door panel assembly may further include a baffle that can move relative to the door panel body between a closed position and an open position. When the baffle is in the closed position, the baffle closes the circular opening, and when the baffle is in the open position, the baffle does not close the circular opening.

[0012] According to this solution, the circular opening provides a passage for the cable to enter the electrical cabinet from the outside of the electrical cabinet, and when the cable is inserted into the interior of the electrical cabinet, the bottom wall of the circular opening can support the cable.

[0013] In some aspects, the door panel assembly may further include a baffle spring configured to bias the baffle toward the closed position.

[0014] According to this solution, when no cable is inserted into the interior of the electrical cabinet, the baffle closes the circular opening, so that the electrical cabinet is in an environment isolated from the outside, preventing foreign objects from the outside from entering the electrical cabinet.

[0015] In some solutions, a guide groove may be provided on the baffle plate, and a guide protrusion may be provided on the door panel body, and the guide protrusion is inserted into the guide groove to guide the baffle plate to move relative to the door panel body.

[0016] In some embodiments, when the cable is inserted into the inner space of the cabinet, the grounding switch is in a first state; when the cable is not inserted into the inner space of the cabinet, the grounding switch is in a second state.

[0017] According to the scheme, when the cable is inserted into the inner space of the cabinet, the grounding switch is in the open state, and the electrical cabinet is not grounded, so that the electrical cabinet can provide power to the outside. When the cable is not inserted into the inner space of the cabinet, the grounding switch is in the closed state, and the electrical cabinet is grounded, so that the electrical cabinet is in a safe state to avoid electric shock accidents.

[0018] According to a second aspect of the utility model, a box-type transformer vehicle is provided, comprising the electrical cabinet according to the first aspect of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to make the purpose, scheme and advantages of the technical solution of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described in conjunction with the drawings of the specific embodiments of the utility model. Unless otherwise specified, the terms used in this article have the usual meanings in the art. The same reference numerals in the drawings represent the same components.

[0052] Figure 1 A schematic diagram of an electrical cabinet 100 according to an embodiment of the utility model is shown. The electrical cabinet 100 can be used in a box-type transformer vehicle. The box-type transformer vehicle including the electrical cabinet 100 can provide backup power for important facilities. For example, when a power outage occurs, the box-type transformer vehicle carries the electrical cabinet 100 to the location of the important facilities and supplies power to the important facilities to ensure that the important facilities are always powered. It should be understood that the electrical cabinet 100 of the utility model is not intended to be limited to application only in box-type transformer vehicles, and can also be used in any other suitable application scenarios.

[0053] In the prior art, the cable is connected to the electrical cabinet 100 from the bottom of the electrical cabinet 100, which results in the need for space for wiring in the lower part of the electrical cabinet 100, making the volume of the electrical cabinet 100 larger, and also causing the center of gravity of the electrical cabinet 100 to be higher, which is particularly detrimental to the stability of the box-type transformer vehicle. For this reason, in the present utility model, the position where the cable 10 is connected to the electrical cabinet 100 is changed from the bottom of the electrical cabinet 100 to the operating surface 112 of the electrical cabinet 100, and the operating surface 112 is perpendicular to the horizontal plane. In other words, the cable 10 is connected to the electrical cabinet 100 from the facade 112 of the cabinet body 110 of the electrical cabinet 100. In this way, there is no need to provide space in the lower part of the electrical cabinet 100 for the cable 10 to pass through, which reduces the volume of the electrical cabinet 100 and also lowers the center of gravity of the electrical cabinet 100.

[0054] Specifically, the operation surface 112 has a manipulation port 114, the cable 10 (eg, Figure 1 The three-phase cable shown in FIG. 1 extends from the interior of the electrical cabinet 100 through the operating opening 114. The electrical cabinet 100 includes a door panel assembly 120, which is disposed on the operating surface 112. The door panel assembly 120 can move between a first position and a second position relative to the cabinet body 110. When the door panel assembly 120 is in the first position (i.e., the door panel assembly 120 is closed), the door panel assembly is positioned at the operating opening 114, at which time the door panel assembly 120 closes the operating opening 114, and the operator cannot enter the interior of the electrical cabinet 100 through the operating opening 114; when the door panel assembly 120 is in the second position (i.e., the door panel assembly 120 is open), the door panel assembly 120 is positioned outside the operating opening 114, at which time the door panel assembly 120 does not close the operating opening 114, and the operator can enter the interior of the electrical cabinet 100 through the operating opening 114.

[0055] The above arrangement brings a new problem, because when the door panel assembly 120 is in the second position, the operator can enter the interior of the electrical cabinet 100 through the operating port 114. Once the electrical cabinet 100 is in a live state at this time, the operator will face the risk of electric shock. To this end, the electrical cabinet 100 of the utility model further includes an interlock assembly 140, which associates the door panel assembly 120 with the grounding switch assembly 130. When the door panel assembly 120 is opened, the grounding switch (not shown) cannot be operated to ensure that it is maintained in the closed state, so that the electrical cabinet 100 is in a safe grounding state; only when the door panel assembly 120 is closed, the grounding switch can be operated to switch the state.

[0056] Specifically, the grounding switch assembly 130 includes an opening 132, and the opening 132 is arranged on the cabinet 110. The grounding switch is configured to be manipulated via the opening 132 to switch between a first state and a second state. When the grounding switch is in the first state (open), the electrical cabinet 100 is not grounded, and when the grounding switch is in the second state (closed), the electrical cabinet is grounded. The interlock assembly 140 is configured so that when the door panel assembly 120 is closed (the operator cannot enter the interior of the electrical cabinet 100), the opening 132 is not closed (the state of the grounding switch can be switched); when the door panel assembly 120 is opened (the operator can enter the interior of the electrical cabinet 100), the opening 132 is closed (the state of the grounding switch cannot be switched).

[0057] Preferably, when the cable 10 is inserted into the inner space of the cabinet 110, the grounding switch is in an open state, and the electrical cabinet 100 is not grounded, so that the electrical cabinet 100 can provide power to the outside. When the cable 10 is not inserted into the inner space of the cabinet 110, the grounding switch is in a closed state, and the electrical cabinet 100 is grounded, so that the electrical cabinet 100 is in a safe state to avoid electric shock accidents. According to the above arrangement, when the cable 10 is not inserted, the electrical cabinet 100 is in a safe grounded state. At this time, if the operator opens the door panel assembly 120, because the action opening 132 of the interlock assembly 140 is closed, the grounding switch cannot be operated to change the state, so as to ensure that the grounding switch is maintained in a closed state, thereby ensuring that the electrical cabinet 100 is maintained in a safe grounded state, so as to ensure that the operator has no safety hazards of electric shock.

[0058] Preferably, if Figure 3 As shown, the interlock assembly 140 may include a switch baffle 142 . When the door panel assembly 120 is in the first position, the opening 132 is not closed by the switch baffle 142 . When the door panel assembly 120 is in the second position, the opening 132 is closed by the switch baffle 142 .

[0059] Preferably, if Figure 3 As shown, the interlocking assembly 140 may further include a connecting rod 144, a stop plate 146 and a stop pin 148, and the switch baffle 142 is fixed to the connecting rod 144. The connecting rod 144 is configured to move linearly, and the stop pin 148 is configured to move rotationally along the axis. The movement of the door panel assembly 120 can actuate the stop pin 148 to rotate, and the rotation of the stop pin 148 can actuate the stop plate 146, and then the movement of the stop plate 146 causes the connecting rod 144 to move, and finally the connecting rod 144 drives the opening 132 to move. Through the above transmission: door panel assembly 120→stop pin 148→stop plate 146→connecting rod 144→switch baffle 142→grounding switch assembly 130, the interlocking of the door panel assembly 120 and the grounding switch assembly 130 is achieved.

[0060] In addition, the interlock assembly 140 may further include a return spring 149 that biases the stop pin 148 (e.g., Figure 2 The door panel assembly 120 is biased upward as shown in the figure, so that the switch baffle 142 is biased in the position of closing the opening 132. When the door panel assembly 120 is moved out of the cabinet, the return spring 149 provides a biasing force to the stop pin 148, and then the switch baffle 142 is kept in the position of closing the opening 132 through the interlock assembly 140, so that the grounding switch cannot be operated to switch the state (that is, keep the closed state to provide the grounding function).

[0061] Alternatively, if Figure 4A , Figure 4B , Figure 5A and Figure 5B As shown, the door panel assembly 120 may include a door panel body 122 (eg, Figure 6 As shown) and the card plate 124 (as Figure 7 As shown in FIG. 1 , when the door panel assembly 120 is closed, the card plate 124 is assembled to the door panel body 122, and the card plate 124 cooperates with the door panel body 122 to form a circular opening 150 for the cable 10 to extend out. An interlocking hole 125 and a locking hole 126 are formed on the card plate 124, and the interlocking hole 125 is configured to drive the stop pin 148 to rotate, and the card plate 124 is detachably assembled to the door panel body 122 via the locking hole 126.

[0062] Preferably, the door panel assembly 120 may further include a baffle 128 (eg Figure 8 As shown), the baffle 128 can be in a closed position (as shown) relative to the door panel body 122. Figure 4B and Figure 5B ) and the open position (as Figure 4A and Figure 5A When the baffle 128 is in the closed position, the baffle 128 closes the circular opening 150; when the baffle 128 is in the open position, the baffle 128 does not close the circular opening 150. The circular opening 150 provides a passage for the cable 10 to enter the electrical cabinet 100 from the outside of the electrical cabinet 100, and when the cable 10 is inserted into the interior of the electrical cabinet 100, the bottom wall of the circular opening 150 can support the cable 10.

[0063] In addition, the door panel assembly 120 may further include a baffle spring 129, which is configured to bias the baffle 128 toward the closed position. In this way, when no cable 10 is inserted into the interior of the electrical cabinet 100, the baffle 128 closes the circular opening 150, so that the electrical cabinet 100 is in an environment isolated from the outside, and foreign objects from the outside are prevented from entering the electrical cabinet 100. Preferably, a guide groove may be provided on the baffle 128, and a guide protrusion may be provided on the door panel body 122, and the guide protrusion is inserted into the guide groove to guide the baffle 128 to move relative to the door panel body 122.

However, it will be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations may be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention may be combined without exceeding the protection scope of the present invention, which is determined by the appended claims.
