Description

Protection device for ammeter case Technical Field The utility model relates to the field of ammeter boxes, in particular to a protection device for an ammeter box. Background An ammeter box is a protection device specially used for installing an electric energy metering instrument (such as an ammeter). The waterproof and dustproof anti-explosion waterproof and anti-corrosion plastic is generally made of materials such as plastics (such as ABS engineering plastics, polycarbonate transparent PC materials, fiber reinforced polyester materials and the like) and metals, and has the characteristics of waterproof, dustproof, explosion-proof, corrosion resistance and the like. The ammeter box is used for monitoring electric energy and measuring the electric quantity by measuring the electric quantity through an ammeter and recording the electric quantity, and a load switch is generally adopted for controlling the flow of the electric energy to prevent overload. The inside configuration such as business turn over line switch, electric wire that contains of ammeter case can protect electric energy metering device and circuit, prevents operation instability or potential safety hazard that external factor leads to. For example, the grant bulletin number, CN203870135U, discloses an ammeter box, which comprises a box body with an ammeter therein, wherein heat dissipation holes are formed in two sides of the box body, a box cover is arranged in front of the box body, and a transparent cover is arranged on the box cover. The smoke sensor and the temperature sensor are arranged to solve the defect that the internal condition is difficult to detect in the prior art, and the smoke control alarm can remind community operators on duty in time so as to reduce injuries caused by accidents.
