Abstract
The utility model discloses a high voltage observation window of a medium voltage armored withdrawable metal enclosed switch cabinet. The high voltage observation window is installed in an observation hole of a switch panel of the middle-voltage armored withdrawable metal enclosed switch cabinet and comprises an observation window front frame, an observation window rear frame, pads and toughened glass. The observation window front frame and the observation window rear frame are installed on the switch panel through fasteners and are positioned on the external surface and the internal surface of the switch panel respectively. The observation window front frame and the observation window rear frame are hollow. The pads and the toughened glass are clamped between the observation window front frame and the observation window rear frame. Compared with the prior art, the high voltage observation window is advantageous by high safety performance and is more convenient to be replaced after being damaged.
Description
Technical field
The utility model relates to middle pressure armored withdraw type metal enclosed switch cabinet technical field, particularly the high pressure observation window of middle pressure armored withdraw type metal enclosed switch cabinet.
Background technology
Middle pressure metal enclosed switchgear refers to a kind of combined electric appliance; it can be loaded on circuit breaker, on-load switch, contactor, isolating switch, fuse, instrument transformer, lightning arrester, capacitor, bus and corresponding measurement mechanism, control device, protective device, monitoring diagnosis device, signalling, interlock and communicator in the rectangular metal shell; middle pressure refers to more than the rated voltage 3kV, the electric pressure that 100kV is following.
Middle pressure metal enclosed switchgear is divided into open metal switch apparatus, closed metal switchgear and sealed metal switchgear by overall structure types.Mounting means by the switchgear internal unit is divided into fixed, withdraw-type.Be divided into box, compartment and armored according to the separation mode of each several part in the cabinet.
Armored withdraw type metal enclosed switch cabinet is the domestic in recent ten years very fast product of development.KYN1-12 type such as 12kV was namely developed in 1985.This structure is because product reliability is high, and maintenance and renewal circuit breaker are easy, have used new insulating material.
Press armored withdraw type metal enclosed switch cabinet to be provided with observation window at present, in order to observe the ruuning situation of pressing armored withdraw type metal enclosed switch cabinet inside.But existing observation window generally is exactly to adopt sealing joint strip and glass to consist of, and its security performance is lower.
The utility model content
Technical problem to be solved in the utility model is to provide for the existing deficiency of prior art a kind of high pressure observation window of middle pressure armored withdraw type metal enclosed switch cabinet.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
The high pressure observation window of middle pressure armored withdraw type metal enclosed switch cabinet, be installed in the switch panel inspection hole of pressure armored withdraw type metal enclosed switch cabinet, it is characterized in that, also comprise the front frame of observation window, observation window after-frame, pad, toughened glass, the front frame of described observation window and observation window after-frame are installed on the switch panel by securing member and lay respectively on the outer surface and inner surface of switch panel, hollow out in the middle of frame and the observation window after-frame before the observation window, described pad and toughened glass are clipped between the front frame of described observation window and the observation window after-frame.
Rib before the inner edge of frame is provided with toughened glass before described observation window, rib after the inner edge of described observation window after-frame is provided with toughened glass, described pad and toughened glass are clipped in behind the toughened glass of rib and observation window after-frame before the toughened glass of frame before the described observation window between the rib.
In a preferred embodiment of the present utility model, rib is arranged at intervals with elastic clip behind the toughened glass of described observation window after-frame.
In a preferred embodiment of the present utility model, the uniform nut that is inlaid with in the frame before described observation window, the entrance of nut is towards the inboard, nut location before the uniform bolt hole that is provided with on described observation window after-frame, the bolt hole position on the described observation window after-frame and described observation window in the frame becomes one-to-one relationship.
Owing to having adopted technique scheme, the utility model compared with prior art has advantages of that security performance is high, and it is convenient to change after damaging simultaneously.
Description of drawings
Fig. 1 is back of the present utility model schematic diagram.
Fig. 2 is cutaway view of the present utility model.
Embodiment
Further describe the utility model below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, the high pressure observation window of the middle pressure armored withdraw type metal enclosed switch cabinet that provides among the figure, be installed in the switch panel inspection hole of pressure armored withdraw type metal enclosed switch cabinet, it also comprises the front frame 100 of observation window, observation window after-frame 200, pad 300, toughened glass 400.
Hollow out in the middle of frame 100 and the observation window after-frame 200 before the observation window; The frame 100 interior uniform nuts 110 that are inlaid with before observation window, the entrance of nut 110 is towards the inboard; Nut 110 positions before the uniform bolt hole 210 that is provided with on observation window after-frame 200, bolt hole 210 positions on the observation window after-frame 200 and observation window in the frame 100 become one-to-one relationship.
The inner edge of frame 100 is provided with rib 120 before the toughened glass before observation window, rib 220 after the inner edge of observation window after-frame 200 is provided with toughened glass, in order to clamp toughened glass 400, rib is arranged at intervals with elastic clip 221 behind the toughened glass of observation window after-frame 200.Elastic clip 221 is integrated with observation window after-frame 200.
During installation, at first frame before the observation window 100 is pressed on the switch panel outer surface, after installing pad 300, toughened glass 400, observation window after-frame 200 is pressed on the switch panel inner surface, passes the nut 110 that screws in frame 100 before the observation window with the bolt hole 210 of bolt from observation window after-frame 200 and get final product.After installing, pad 300 and toughened glass 400 are clipped between the rear rib 220 of the front rib 120 of toughened glass of the front frame 100 of observation window and observation window after-frame 200.
