The device can directly fix each electrical equipment on apron detection mechanism 2 before using (this apron detection mechanism 2 can regard as looped netowrk cabinet back shroud or curb plate to use, and recommends as the detection device on the low pressure looped netowrk cabinet to use, because its voltage is less, the part on the detection device can not damaged easily), when concrete installation, install each electrical equipment on different regions according to suitable position.
As shown in fig. 1, 2 and 5, a clamping cover 202 is connected to one side of the alarm connecting frame 5 away from the cabinet frame 1, an air injection bag 203 is installed in the clamping cover 202, storage covers 204 are installed on both sides of the clamping cover 202, an adjusting bag 3 communicated with the air injection bag 203 is installed in the storage cover 204, an extension strip 4 is installed in the adjusting bag 3, and both the extension strip 4 and the detection sheet 205 can be made of copper materials; and be in intercommunication department between regulation bag 3 and the gas injection bag 203 installs trigger 8 the lateral wall of extension strip 4 is installed and is run through screens cover 202 and the detection piece 205 of being connected with the apron body 201, install a plurality ofly on the warning link 5 and adjust the whistle 206 of the inside intercommunication of bag 3, the one side of annotating gasbag 203 keeping away from screens cover 202 is equipped with screens cover 202 inner wall connection and is driven and extrude gas injection bag 203 towards the deflection post 7 of gas injection in the regulation bag 3 by the driver, through current start on the extension strip 4 during trigger 8, follow annotate gasbag 203 towards the gas injection in the regulation bag 3.
When the device is used daily, the deflection column 7 rotates all the time, but the trigger 8 is not opened, so the whistle 206 does not rotate at this time, however, once a certain component leaks electricity, at this time, current exists in the area of the cover plate body 201 corresponding to the component immediately, then the detection sheet 205 in the area guides the current to the extension strip 4 corresponding to the area and enables the current to pass through the trigger 8, the trigger 8 immediately triggers the opening of the communication part between the gas injection bag 203 and the adjustment bag 3, then the deflection column 7 which rotates continuously rotates all the time rotates, the gas in the gas injection bag 203 (namely the inflatable air bag) is continuously filled into the adjustment bag 3, at this time, the gas in the adjustment bag 3 gradually fills the large adjustment bag 3, and meanwhile, part of the gas is blown out of the whistle 206, so that a user is warned that the electricity leakage occurs at the part.
As shown in fig. 2 and 5, the adjustment bag 3 comprises a bag body 301 installed in a storage cover 204, a plurality of expansion grooves 302 in a V-shaped structure are formed in the bag body 301, two extension clamp groups 303 symmetrical with respect to the bag body 301 are installed on the storage cover 204, each extension clamp group 303 comprises a fixed clamp block 304 connected with the inner wall of the storage cover 204 and a movable clamp block 305 movably connected with the inner wall of the storage cover 204, and a stretching strip 306 is installed between the fixed clamp block 304 and the movable clamp block 305; the extension clip set 303 is present to secure the expansion flap 307 between the fixed clip block 304 and the movable clip block 305 via a tension bar 306 (e.g., a spring or leaf spring) to prevent the expansion flap 307 from opening directly after the bladder 301 is inflated. An expansion sheet 307 which is connected with the capsule body 301 in a sealing way is arranged between the fixed clamping block 304 and the movable clamping block 305, one end of the capsule body 301, which is far away from the air injection bag 203, is connected with an expansion bag 308 in a sealing way, and a positioning spacer 309 is arranged on the side wall of the expansion bag 308.
This regulation bag 3 can be under the prerequisite of carrying out the pertinence detection to each region to and lifting device's detection scope and application scope under the condition that does not increase equipment volume, can detect looped netowrk cabinet back shroud and side cap board simultaneously.
Under the normal detection condition, namely, when only detecting each area on the cover plate body 201, once the current exists in the area corresponding to the detection sheet 205, the detection sheet is led into the extension bar 4 corresponding to the area and passes through the trigger 8, the trigger 8 immediately triggers the opening of the communication position between the gas injection bag 203 and the adjustment bag 3, and then the current directly enters the gas adjustment bag body 301 after being blown out from the gas injection bag 203, so that the pressure in the gas adjustment bag body 301 is gradually increased, and then the expansion groove 302 on the gas adjustment bag body 301 is gradually opened until being flattened.
Once a user needs to detect a plurality of ring main units or detect the side walls of the ring main units, the positioning spacer 309 is pulled to enable the ring main units to gradually move with the expansion bag 308, and at the moment, the expansion piece 307 is gradually stretched until the expansion piece is flattened, so that the cover plate body 201 is installed on the whole ring main unit; the user can then fix the positioning spacer 309 to the alarm attachment bracket 5.
Because a plurality of equipment installation blocks 207 are arranged on the cover plate body 201, materials such as an insulating ring and the like can be arranged at the connection position between the equipment installation block 207 and the cover plate body 201, a repeated separation strip 209 which is in a cross structure and divides the equipment installation block 207 into four areas is arranged on the equipment installation block 207, the repeated separation strip 209 can also be made of an insulating material, and a plurality of insertion holes 208 are formed in the repeated separation strip 209. The arrangement is to further divide the cover plate body 201 into smaller areas, so that when the devices installed on the ring main unit are dense, further detection, positioning and focusing operations can be performed, and when the devices are installed on the side wall, the positioning spacer 309 can be fixed at different positions by the repeated dividing strips 209, even if the positioning spacer 309 and the storage cover 204 are in an inclined state, the positioning spacer can still be realized.
If a plurality of small parts are installed on the side wall of the ring main unit, the small parts are respectively installed in different areas separated by the repeated separation bar 209, even if the installation position of the small parts is higher than that of the storage cover 204, at this time, a user can pull out the positioning separation block 309 first, and then connect the positioning separation block 309 with the repeated separation bar 209 corresponding to the part; the connection mode is the same as that of the storage cover 204, i.e. the structure of the insertion hole 208 is the same as that of the snap post hole 506.
