Problems solved by technology

At present, the power grid implements 24-hour monitoring of the distribution transformers in the basement power distribution room through the intelligent public transformer acquisition terminal, and transmits various parameters of the distribution transformers to the main station through GPRS (or CMDA) wireless data transmission, but Due to the weak signal in some basement areas, the installed signal amplifying device is limited by the unstable working power supply, which cannot provide reliable battery life after the transformer is out of power. very unreliable

Embodiment 1

[0039] Such as Figures 1 to 3As shown, the present invention provides a reliable signal amplifying device, comprising an installation box 1 and a signal amplifier 2 and a power supply module 3 disposed in the installation box 1, the power supply module 3 is electrically connected to the signal amplifier 2, and the power supply module 3 includes a power supply Adapter 31 and accumulator 32, power adapter 31 is electrically connected with two external power sources 33 simultaneously, and accumulator 32 is electrically connected with power adapter 31, and power adapter 31 is provided with electric storage circuit 311 and is used for switching the switching of two external power sources 33 switch 312 . By setting the power adapter 31 to be electrically connected to two external power sources 33 at the same time, the power adapter 31 is provided with a switching switch 312, which can switch the two external power sources 33, so that when one of the external power sources 33 appear...

Embodiment 2

[0046] The main difference between this embodiment and the first embodiment is that the installation box is provided with a slider, and the side wall of the installation box is provided with an opening for the slider to pass through.

[0047] Such as Figures 4 to 6 As shown, the installation box 1 is provided with a slider 11, and the side wall of the installation box 1 is provided with a port 12 for the slider 11 to pass through. cavity 41 , and a fixing groove 411 matching with the slider 11 is provided in the installation cavity 41 . The advantage of this arrangement is that by setting the slider 11, the slider 11 passes through the opening 12 and cooperates with the fixing groove 411 in the installation cavity 41 to fix the installation box 1, so that the installation box is not easy to fall from the installation cavity, ensuring the signal The reliability of the use of the amplification device.

[0048] The inner wall of the port 12 is provided with a guide edge 121, t...

Embodiment 3

[0054] The main difference between the present embodiment and the second embodiment is that the limiting plate is slidably connected with the inner wall of the installation box.

[0055] Such as Figure 9 and 10 As shown, the limit plate 13 is slidably connected with the inner wall of the installation box 1, the two ends of the limit plate 13 are provided with magnets 133, the installation box is provided with an electromagnet, and the electromagnet includes a first electromagnetic magnet located above the limit plate 13. Iron 134 and the second electromagnet 135 that is positioned at the limit plate 13 below, when the second electromagnet 135 was energized, the limit plate 13 cooperated with the second electromagnet 135 and blocked the port, and when the first electromagnet 134 was energized, the limit The plate 13 cooperates with the first electromagnet 134 and is away from the through port. The advantage of this setting is that by setting the limit plate to slide and conn...

Abstract

The present invention provides a reliable signal amplifier device, including the installation box and the signal amplifier and power supply module set in the installation box. The power supply module is connected to the signal amplifier.The external power supply is connected, the battery is connected to the power adapter, and the power adapter is equipped with a stress circuit and a casting switch. The switch can switch the two external power supply, so that when one of the external power supply fails the power, the other is external, the other is external, and the other is external.The power supply can continue to power the signal amplifier. When the two external power supplies cannot be powered at the same time, the stress circuit is powered on the signal amplifier as soon as possible, and then the battery continues to power the signal amplifier.Time makes the use of signal amplification device more reliable.

Description

technical field [0001] The invention relates to the technical field of signal amplifying devices, in particular to a reliable signal amplifying device. Background technique [0002] With the rapid development of information technology, the intelligent equipment applied to the distribution network is becoming more and more advanced. The operation status of the field equipment can be grasped in real time through wireless data transmission instead of the previous manual inspection, making the power monitoring system more comprehensive and perfect. At present, the power grid implements 24-hour monitoring of the distribution transformers in the basement power distribution room through the intelligent public transformer acquisition terminal, and transmits various parameters of the distribution transformers to the main station through GPRS (or CMDA) wireless data transmission, but Due to the weak signal in some basement areas, the installed signal amplifying device is limited by th...
