Description
Technical Field
The utility model belongs to the technical field of electric power facility distribution unit, concretely relates to movable observation window device of medium voltage switchgear back cabinet door.
Background
The feeder switch cabinet is also called as a metal closed switch device, wherein the feeder switch cabinet is a switch device which can close, bear and open current under the condition of a normal loop and can close, bear and open current under the condition of an abnormal loop within a specified time. The switch cabinet is mainly connected with electric loads such as a transformer, a motor and the like, two electric devices are usually configured in places with high electric reliability, and one electric device works and one electric device is standby and is switched periodically. Before standby equipment is powered on, insulation measurement work needs to be carried out, and the following steps need to be carried out when insulation measurement is carried out on the conventional switch cabinet: the method comprises the steps of equipment power failure → grounding switch input → rear cabinet door dismantling → grounding switch disconnection → load measurement insulation → grounding switch input → rear cabinet door installation → grounding switch disconnection → equipment power transmission, and is very complicated in operation, and personnel electric shock, electric grounding switch closing or electric power transmission accidents with the grounding switch can be caused by carelessness.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel movable observation window structural style of medium voltage switchgear back cabinet door aims at changing the operating mode when medium voltage switch load measurement is insulating, ensures that operation process simplifies, safe and reliable.
The utility model discloses a realize through following technical scheme: the utility model provides a movable observation window of cubical switchboard cabinet door which characterized in that: a window is formed in a rear cabinet door of the switch cabinet, a frame of the window is hinged with a movable observation window cover plate, an electromagnetic lock is fixed on the outer wall of the cabinet door on one side of the window, an electromagnetic lock bolt is arranged on the electromagnetic lock, and a socket matched with the electromagnetic lock bolt is arranged on the movable observation window cover plate; the electromagnetic lock is powered by the power supply air switch, and the coil of the electromagnetic lock is connected with the contact of the electrified display and the operation button of the electromagnetic lock in series.
Preferably, the window is arranged above the rear cabinet door of the switch cabinet. The window is rectangular and chamfered at four corners. The movable observation window cover plate is in a rectangular plate shape.
The medium voltage switch cabinet of the fixed observation window of the existing rear cabinet door needs to carry out the following operations in sequence when carrying out load measurement insulation work: equipment power failure → grounding switch input → rear cabinet door removal → grounding switch disconnection → load measurement insulation → grounding switch input → rear cabinet door installation → grounding switch disconnection → equipment power transmission; adopt the utility model discloses the insulating work needs to carry out following operation to the back load survey: power failure of equipment → opening of an observation window → insulation of a measuring load → closing of the observation window → power transmission of the equipment.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model provides a medium voltage switch must frequently operate the ground connection switch when measuring the load is insulating, demolishs the back cabinet door, and the loaded down with trivial details problem of operation process reaches through movable window's use and need not drop into the ground connection switch, need not demolish the back cabinet door, opens movable window can be safe, measure the insulating purpose of load rapidly.
Drawings
Fig. 1 is a schematic structural view of the present invention, wherein the left view observation window is closed and the right view observation window is opened;
fig. 2 is an electrical schematic diagram of the present invention.
In the figure: 1. the switch cabinet comprises a switch cabinet back cabinet door, 2. a movable observation window cover plate, 3. a socket, 4. an electromagnetic lock, 5. an electromagnetic lock bolt, 6. a power supply air switch, 7. a live display contact, 8. an electromagnetic lock coil, 9. an electromagnetic lock operation button and 10. a window.
Detailed Description
The present invention is further described below.
A rectangular window 10 is arranged above a rear cabinet door 1 of a switch cabinet, and the frame of the window 10 is connected with a rectangular movable observation window cover plate 2 through a hinge. An electromagnetic lock 4 is fixed on the outer wall of the cabinet door on one side of the window 10, an electromagnetic lock bolt 5 is arranged on the electromagnetic lock 4, and a socket 3 matched with the electromagnetic lock bolt 5 is arranged on the movable observation window cover plate 2; the electromagnetic lock 4 is connected with the power supply air switch 6, and the electromagnetic lock coil 8 is connected with the live display contact 7 and the electromagnetic lock operating button 9 in series. The opening and closing operations of the electromagnetic lock 4 are determined by controlling the electrification and the loss of the electricity of an electromagnetic lock coil 8 through an electrified display contact 7 and an electromagnetic lock operation button 9. The movable observation window cover plate 2 is opened downwards, when the bolt of the electromagnetic lock is inserted into the socket, the movable observation window is in a closed state, and when the bolt of the electromagnetic lock is withdrawn from the socket, the movable observation window is in a downwards opened state.
As shown in fig. 1 and 2, the operating power of the electromagnetic lock 4 is supplied by a power supply idle switch 6, the power supply idle switch 6 is in a closing state during the operation of the equipment, when the load is electrified, a contact 7 of the electrified display is disconnected, the electromagnetic lock 4 is locked when the power is lost, a bolt 5 of the electromagnetic lock is inserted into a socket 3 and cannot be operated, and a movable observation window cover plate 2 cannot be opened; when the load is not electrified, the contact 7 of the electrified display is closed, the electromagnetic lock operation button 9 is pressed at the moment, the coil 8 of the electromagnetic lock is electrified, the electromagnetic lock bolt 5 can be manually opened, and the movable observation window cover plate 2 can be opened by an operator to measure the load insulation.
