Problems solved by technology

For a long time, the "five defenses" have basically been guaranteed by human subjective factors such as the work experience and sense of responsibility of the operators in the power system, and lack of corresponding technical equipment means. From the objective conditions, the types of equipment used in the power system There are many, complex operation items, wide distribution of work locations, and different working conditions, which lead to human error operations, frequent occurrence of vicious accidents, and great harm to production and people's lives. Its social impact and economic losses are difficult to calculate

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Portable monitors for the five defenses of power systems, hereinafter also referred to as portable monitors or monitors.

[0037] 1, Fig. 1 is the outline drawing of the present invention, has antenna 2, operation button 3, test head 5, display screen 9, liquid crystal display information 10, RS232 interface socket 11, charger socket 12, and described electric test component is prior art , its composition is shown in Figure 4, the weak signal obtained by the input circuit of the test head 5 is sent to the comparison circuit after voltage doubler rectification, voltage amplification and filtering. The output of the comparator circuit controls the oscillator circuit. The output pulse of the oscillating circuit is sent to the sound and light alarm through the CPU, and the alarm sends out buzzing and flashing signals according to ...

Abstract

This invention discloses a portable monitor of a power system for preventing error open and close breakers characterizing in: setting a card-read component, an electricity verifying component, a CPU, an operation key, a LCD display screen, a sound and optical warning signal and RS 232 interface exchanging data with the primary computer, before operation, the set state software writes the operation content in the monitor, reads content recorded in the monitor, stores data in the data base, sets up files to be managed and enquired, which can prevent error operation.

Description

technical field [0001] The invention relates to a safety protection device for power system operation. Background technique [0002] The importance of safe production to the power system is self-evident, and the "five defenses" are extremely critical to ensure the safety of the power grid. The so-called "five defenses" refer to: 1. Prevent wrong opening and closing of the circuit breaker; 2. Prevent pulling and closing the disconnector with load; stray into live interval. For a long time, the "five defenses" have basically been guaranteed by human subjective factors such as the work experience and sense of responsibility of the operators in the power system, and lack of corresponding technical equipment means. From the objective conditions, the types of equipment used in the power system There are many, complex operation items, wide distribution of work locations, and different working conditions, which lead to human error operations, frequent occurrence of vicious acciden...
