Abstract
The utility model discloses a mechanical interlocking mechanism of a removable switch cabinet. The mechanical interlocking mechanism comprises a valve mechanism (1) and a circuit breaker room door (6). A guide rod (2) is fixed on the valve mechanism (1). The guide rod (2) is hinged with a connecting rod (3). The connecting rod (3) can rotate around a pin roll (4). A bending plate (5) is welded on the circuit breaker room door (6). The interlocking mechanism satisfies a requirement of a national standard GB 3906-2006. When the valve is not closed, the circuit breaker room door can be locked at a circuit breaker chamber working position. Operation personnel can be prevented from opening a compartment with the circuit breaker so that good personnel protection is achieved.
Description
Technical field
The utility model relates to a kind of interlocked operation mechanism of power distribution withdraw-type switch cabinet.
Background technology
Withdraw-type switch cabinet is a mesolow electrical power distribution system indoor complete set of equipments commonly used.In the system of rated voltage 12kV, 6kV and 3kV three-phase alternating current 50Hz, be widely used especially.Based on the explanation among the GB GB3906-2006 " the touched compartment of interlocked control "; Breaker chamber belongs to " the touched compartment of interlocked control ", requires " these compartments should be furnished with interlock and change compartment so that palp major loop parts just can be opened when not charged and ground connection or after isolated location and corresponding valve are closed ".The utility model is exactly the requirement to GB 3906-2006, withdraw-type switch cabinet is improved the interlocking that increases.
Summary of the invention
The utility model is the requirement to GB 3906-2006, and a kind of mechanical interlock mechanism of withdraw-type switch cabinet is provided, and makes circuit breaker under the situation that service position and valve are not closed, can't open the breaker chamber door, improves barrier propterty.
The technical scheme that the utility model adopts is: a kind of mechanical interlock mechanism of withdraw-type switch cabinet; Comprise valve mechanism and breaker chamber door; It is characterized in that: a fixing guide rod on valve mechanism; Guide rod is hinged with a connecting rod, and connecting rod can rotate around bearing pin, on the breaker chamber door, is welded with bent plate.
When circuit breaker when test position moves to the service position, valve is opened in the valve mechanism action, drives guide rod and connecting rod simultaneously and catches on the bent plate on the breaker chamber door, the breaker chamber door is lockable; When circuit breaker moves to test position from the service position, valve is closed in the valve mechanism action, drives guide rod and connecting rod and removes from breaker chamber door bent plate position, and the breaker chamber door can be opened.
The utility model withdraw-type switch cabinet mechanical interlock mechanism; Utilize the difference of circuit breaker in experiment position and service position; Drive the principle of valve mechanism action, on valve mechanism, increase some necessary mechanical parts, form an interlock connection with the breaker chamber door; Thereby when realizing opening the breaker chamber door, circuit breaker is in the experiment position and valve mechanism is closed.Satisfy the requirement of GB GB 3906-2006, better to personnel protection, in the breaker chamber service position and valve can pin the breaker chamber door when not closed, prevent that operating personnel from opening the belt fuser compartment.
Description of drawings
Fig. 1 is the structural representation of the utility model withdraw-type switch cabinet mechanical interlocking machine mechanism circuit-breaker when the experiment position;
Fig. 2 is the structural representation of the utility model withdraw-type switch cabinet mechanical interlocking machine mechanism circuit-breaker when the service position.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: 1, valve mechanism 2, guide rod 3, connecting rod 4, bearing pin 5, bent plate 6, breaker chamber door
Shown in figure; The utility model withdraw-type switch cabinet mechanical interlock mechanism comprises valve mechanism 1 and breaker chamber door 6; A fixing guide rod 2 on valve mechanism 1, guide rod 2 can be along with valve mechanism moves, and guide rod 2 is hinged with a connecting rod 3; Connecting rod 3 can be welded with bent plate 5 around bearing pin 4 rotations on breaker chamber door 6.
When circuit breaker is in the service position, valve mechanism 1 action, guide rod 2 is with valve mechanism 1 action, and drivening rod 3 rotates, and connecting rod 3 blocks bent plate 5, pins breaker chamber door 6, and as shown in Figure 2, breaker chamber door 6 can't be opened under this state, realizes interlock.
Claims (1)
1. the mechanical interlock mechanism of a withdraw-type switch cabinet is characterized in that: go up a fixing guide rod (2) at valve mechanism (1), guide rod (2) is hinged with a connecting rod (3), and connecting rod (3) can be welded with bent plate (5) around bearing pin (4) rotation on breaker chamber door (6).
