Embodiment 1

[0023] like figure 1 , figure 2 As shown, the outdoor safety meter system includes a box body 1 and a box cover 2 hinged to the box body 1. The box body 1 is concaved to form a storage cavity 3, and the electric meter 4 is arranged in the storage cavity 3. The box cover 2 is provided with a There is an observation port 14; it also includes a temperature circuit breaker 5 connected to the neutral wire and the live wire of the electric meter 4 and a fire extinguishing device 6 sleeved on the neutral wire and the live wire.

[0024] In this embodiment, when the temperature inside the box 1 is higher than the temperature set by the temperature circuit breaker 5, the circuit will be disconnected to avoid spontaneous combustion of the wire due to excessive temperature. Two temperature circuit breakers 5 are provided and are respectively connected to the neutral wire and the live wire, so that the live wire and the neutral wire can be disconnected at the same time. Furthermore, wh...

Embodiment 2

[0026] In this embodiment, on the basis of Embodiment 1, the fire extinguishing device 6 includes a fire extinguishing bag 7 and a fire extinguishing medium disposed in the fire extinguishing bag 7 , and the fire extinguishing bag 7 is provided with a through hole 8 for passing the neutral line and the fire line. Described fire extinguishing bag 7 is made of combustible material.

[0027] Under the situation of ammeter 4 overload or short circuit, when zero wire and fire wire caught fire, fire extinguishing bag 7 is made of inflammable material, and fire extinguishing bag 7 will be burnt, and the fire extinguishing medium that is positioned at fire extinguishing bag 7 will flow out and extinguish flame. The fire extinguishing medium in this embodiment can be dry powder or sand. Since sand is cheap and can be seen everywhere, sand is the preferred fire extinguishing medium of this scheme.

Embodiment 3

[0029] In this embodiment, on the basis of embodiment 1 or embodiment 2, a groove 9 is opened on the upper surface of the box body 1 , and a sealing gasket arranged in the groove 9 is also included.

[0030] The sealing gasket arranged in the groove 9 is used to increase the sealing performance of the box body 1 and the box cover 2, so as to prevent water vapor in the air from entering the box body 1 and corroding the electric meter.

Abstract

The invention provides an outdoor safety type ammeter system. The outdoor safety type ammeter system includes a casing and a case cover which is hinged with the casing, wherein an accommodation chamber is concavely arranged in the casing; and an ammeter is arranged in the accommodation chamber. The outdoor safety type ammeter system also includes a temperature breaker and an extinguishing device, wherein the temperature breaker is connected with a zero line and a fire line; and the zero line and the fire line sleeve the extinguishing device. In the outdoor safety type ammeter system, when the temperature in the casing becomes higher, the temperature breaker automatically turns off the circuit to prevent spontaneous combustion of lead because of over high temperature. When the zero line and the fire line is on fire, the extinguishing device can quickly extinguish the flame to avoid fire propagation.

Description

technical field [0001] The invention relates to an electric meter system, in particular to an outdoor safe electric meter system. Background technique [0002] An electric meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, or a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. The electric meter is generally installed in the electric energy box. At present, most of the electric meters and electric energy boxes are made of plastic materials. When the electric meter is overloaded or short-circuited, it will often cause the electric energy box to catch fire and cause a fire. direct harm to human life. Furthermore, the electric meter box is generally installed outdoors, and long-term wind and rain can easily cause rainwater to enter the electric meter box, causing metal corrosion inside the electric meter box and seriously affecting the service life of the electric meter box.
