Abstract

The utility model belongs to the technical field of intelligent ammeter detection and protection equipment, and relates to an ammeter detection and protection cabinet box device, in particular to an equipment device with a cabinet box structure for placing and protecting an ammeter detection system. A terminal is obliquely arranged on the front side of the bottom of a tool main body with a box frame structure; a small baffle capable of rocking up and down is arranged at the lower end in the middle of the slope of the tool main body; a spring seat is fixedly arranged at a position of the small baffle, corresponding to the slope; a spring is embedded on the spring seat; a contact pad integrated with the spring seat is arranged at a position of the spring seat, near to the slope; an upper contact pad and a lower contact pad are arranged on two sides of the spring seat in a wrapping way; and an earth leakage protective device is fixedly arranged in a space at the bottom of the tool main body, near to the spring seat. For the ammeter detection and protection cabinet box device, the structure is novel, the manufacturing process is simple, the use is safe and reliable, the operation is flexible, the protection on operators is good, and the safety problem due to electric leakage and the like can be effectively avoided.

Description

A kind of ammeter detects protection cabinet case apparatus

Technical field:

The utility model belongs to intelligent electric meter and detects the protection equipment technical field, relates to a kind of ammeter and detects protection cabinet case apparatus, the apparatus of the cabinet box structure of particularly a kind of placement and protection ammeter detection system.

Background technology:

At present, in the ammeter detection protection cabinet case apparatus equipment of common use, for the operating personnel that protect ammeter to detect are not shocked by electricity, often the anti-electricity to the ammeter checkout equipment requires increasingly high; Existing ammeter pick-up unit generally is that anti-electric protection is not set; Operating personnel are in the ammeter testing process; Four connection terminals of ammeter are to expose fully outside; In operating personnel change the process of ammeter, very easily touch this four connection terminals, health is damaged thereby get an electric shock; End is got up, and existing ammeter detects the equipment and the technological ubiquity of protection and complicated integral structure, and usage safety performance is poor, when ammeter detects electric leakage serious, the personal safety coefficient is little in the operating process, and shortcoming such as service life of equipment is short.

Summary of the invention:

The goal of the invention of the utility model is to overcome the shortcoming that prior art exists; Seek to design the ammeter that a kind of new structure is provided and detect protection cabinet case apparatus; Personnel protection panel that can protection against electric shock can avoid effectively that operating personnel get an electric shock in changing the process of table maybe, reduce personal injury to operating personnel; On the cabinet of baffle plate back, be designed with two small front aprons simultaneously; Two small front aprons are simultaneously as power switch, when ammeter is pressed down from above, by the baffle plate retaining down; Thereby the back side of small front apron has a contact power turn-on, ammeter to be powered on the contact of the contact in the cabinet to be detected; When pulling out ammeter, two small front aprons are upspring under the effect of elastic force, and this moment, the contact divided switch power supply to break off, thereby prevented operating personnel's unconscious electric shock in operating process effectively.

To achieve these goals, the agent structure of the utility model comprises frock main body, binding post, small front apron, earth leakage protective device, contact, goes up contact, following contact, spring base and spring; The oblique binding post that is shaped in the groove of the frock bottom part body front side of tank tower formula structure; The middle part lower end on the inclined-plane of frock main body is shaped on the small front apron that can fluctuate; Small front apron inclined surface place fixedly is shaped on spring base; Nested type is shaped on spring on the spring base, spring base be shaped on the contact with the spring base one near the place, inclined-plane, the both sides jacket formula of spring base is shaped on contact and following contact; The bottom of frock main body is installed with earth leakage protective device in the space near spring base; The frock main body that assembling is shaped is installed in the cabinet case of the case structure corresponding with the frock agent structure, constitutes the integral type ammeter and detects protection cabinet case apparatus; Binding post is fixedly mounted on ammeter is pressed above the frock main body, and by the small front apron retaining down, the compressing contact makes contact contact with last contact with following contact and circuit is connected, and binding post energising carrying out ammeter detects; When ammeter is pulled out above frock; Contact is upspring under the effect of spring, makes contact and following contact and last contact separate, and circuit is broken off; Guaranteed that operating personnel can not touch binding post and get an electric shock in changing the process of ammeter, thereby protected operating personnel; The front panel of frock main body is contacting of blocked operation personnel and connection terminal effectively; Simultaneously be pulled out and can break off the power supply of binding post effectively under the situation of not cutting off the electricity supply, thereby the electric shock of effectively avoiding operating personnel not pull out changing ammeter in the process of power supply maybe at ammeter.

The utility model compared with prior art, its novel structure, manufacturing process is simple, and is safe and reliable, flexible operation to operating personnel's good protective, can effectively protect electric leakage to wait the safety problem cause.

Description of drawings:

Fig. 1 is the one-piece construction side-looking principle schematic of the utility model.

Embodiment:

Below through embodiment and combine accompanying drawing to be described further.

Embodiment:

The agent structure of present embodiment comprises frock main body 1, binding post 2, small front apron 3, earth leakage protective device 5, contact 6, goes up contact 7, following contact 4, spring base 8 and spring 9; The oblique binding post 2 that is shaped in front side, frock main body 1 bottom of tank tower formula structure; The middle part lower end on the inclined-plane of frock main body 1 is shaped on the small front apron 3 that can fluctuate; Small front apron 3 inclined surface places fixedly are shaped on spring base 8; Nested type is shaped on spring 9 on the spring base 8, spring base 8 be shaped on the contact 6 with spring base 8 one near the place, inclined-plane, the both sides jacket formula of spring base 8 is shaped on contact 7 and following contact 4; The bottom of frock main body 1 is installed with earth leakage protective device 5 in the space near spring base 8; Binding post 2 is fixedly mounted in the groove on the frock main body 1, and ammeter is pressed above frock main body 1, and small front apron 3 is by under the retaining, and compressing contact 6 makes it contact with last contact 7 with following contact 4 and circuit is connected, and binding post energising carrying out ammeter detects; When ammeter is pulled out above frock; Contact 6 is upspring under the effect of spring 9, makes contact 6 and following contact 4 open in 7 minutes with last contact, and circuit is broken off; Guaranteed that operating personnel can not touch binding post and get an electric shock in changing the process of ammeter, thereby protected operating personnel; Front panel has cut off contacting of operating personnel and connection terminal effectively; Simultaneously be pulled out and can break off the power supply of binding post effectively under the situation of not cutting off the electricity supply, thereby the electric shock of effectively having avoided operating personnel not pull out changing ammeter in the process of power supply maybe at ammeter.

Present embodiment is proof in using practice, and its safe reliability is good, reasonable in design; Use flexible operation, can substitute the instrument and the equipment that use when existing ammeter detects fully, it is accurate to guarantee that ammeter detects data; Detection efficiency is high, has prolonged the serviceable life of equipment simultaneously.
