Safe high-efficiency solid-state relay

Abstract

The invention, which belongs to the technical field of the relay device, discloses a safe high-efficiency solid-state relay comprising a relay body containing a relay chamber and a control chamber. The control chamber and the relay chamber are connected electrically and fixedly. A support rod is arranged at each side of the bottom of the relay body; and a fixed suction plate is arranged on the support rod. A power switch is arranged at the control chamber. Electric plugs are arranged at the relay chamber; a plurality of mounting plates are arranged at one side of the relay chamber and mounting holes are formed in the mounting plate; a cooling plate is arranged in the relay chamber and a cooling slit is formed in one side of the cooling plate. According to the safe high-efficiency solid-state relay, with the mounting plates arranged on the fixed suction plate and the relay chamber, a relay can be installed conveniently and can be installed in various environments, so that the mounting effect of the solid-state relay is improved. Moreover, with the cooling slit and the cooling plate arranged at one side of the relay chamber, cooling of the relay can be carried out conveniently, thereby prolonging the service life of the relay.

[0002] Traditional solid-state relays cannot effectively regulate and control current and voltage, which will greatly reduce the working efficiency of the relay, and it is also not conducive to the use of the relay in various environments, and it cannot timely alarm when the relay has problems. At the same time, it cannot effectively isolate the influence of external current on the relay, which will reduce the working efficiency of the relay

[0003] Chinese invention patent, application number: 201220520100.3, discloses a solid-state relay. The existing relays mainly have the following disadvantages: 1. When connected to the power line, the wiring operation is inconvenient; 2. The overall structure is relatively compact and difficult to dissipate heat, and it works at high temperature for a long time It will shorten the service life of the internal working components; 3. When installing with the control cabinet, bolts are mainly used, and screw holes need to be opened in the control cabinet for installation and positioning. This installation method is time-consuming and laborious, and it is inconvenient to install

[0004] Chinese patent document, application number: 201420343175.8, discloses a relay. As we all know, a solid-state relay is a non-contact switching device composed of microelectronic circuits, discrete electronic devices, and power electronic power devices, and is widely used in circuit control; Existing solid-state relays usually include a relay body and a radiator. The radiator is a heat-dissipating base plate made of metal, and the relay body is set on the heat-dissipating base plate. The problem that electronic components are damaged due to high temperature, which in turn affects the service life of solid state relays
